No permanent lesions were reported, and all patients were fully recovered within 36 weeks. Transient facial palsy remains the most common complication in parotid gland tumor 14 and an important factor of distress both to patients and the surgical team. If the lesion is permanent the consequences are tremendous, resulting in possible cornea ulcers, facial asymmetry, dysphasia, and drooling. Superficial parotidectomy remains the most efficient technique yet available, allowing the surgeon through the complete facial nerve dissection, with better chances of preserving its function. It is still a matter of debate whether the incidence of facial paralysis is higher after malignant tumors resection, due to a more aggressive surgical approach, 23 or after benign lesions, usually with a longer duration of the disease, associated with tumor's adherence and adjacent inflammatory process. It is quite intuitive to relate the increase of tumor's dimension to a higher incidence of complications. In this study, we have demonstrated that tumors with 3. This should be taken into account in the pre-operative evaluation, and consequently, demand a much more careful technique during nerve dissection. All of the 16 cases of recurrence occurred after enucleation of the lesion performed elsewhere, since this approach is not preconized at our institution. As seen in this study, the secondary surgery has a much higher risk of resulting in facial palsy, surely due to perilesional inflammation, fibrosis and lack of anatomical landmarks. Surgery performed after a previous approach of the parotid gland has an odds ratio of 6. This should be recognized when performing the primary surgery, demanding a curative approach to avoid a secondary and, therefore, more risky surgery and during the secondary surgery itself, since the risks of facial nerve injury are significantly higher. On the other hand, duration of the disease had no correlation with a higher risk of facial nerve injury during superficial parotidectomy. The calculated odds ratios were 1. One might expect to find a higher risk of facial nerve injury with longer disease period. The explanation why that was not found in this study remains unclear. Facial nerve injury during superficial parotidectomy remains the most common and most feared complication. In this study, we have found that tumors with 3. Pleomorphic adenoma and benign parotid tumors: Minor salivary gland tumors. Sensory disturbance: A decrease in sensation of skin of the neck, around the face and the lobule occur when the greater auricular nerve or some of its branches are cut. This is required in most parotidectomy procedures. Over time, the area of numbness will shrink, but the lobule of the ear will probably remain numb forever. This occurs because after removing the parotid gland, the nerve endings that normally stimulate saliva production and secretion from the auriculotemporal nerve end up against the skin now that the parotid gland is gone. Because the same neurotransmitter that stimulates salivary release also stimulates sweating, whenever that nerve is activated, it causes sweating instead of salivary release. The severity of this problem can vary from not even noticeable to very severe and troublesome. Treatment options include applying anti-perspirant to the facial skin, injecting botulinum toxin Botox in that region of the skin which blocks the neurotransmitter that causes sweating , surgery to place a barrier just under skin or extensive middle ear surgery to cut the nerve that causes all of these problems near its origin. One way to prevent this complication is to place a barrier between the free nerve endings and the skin at the time of the parotidectomy itself. This barrier can be in the form of sewing the parotid fascia back together thereby covering up those free nerve endings , moving muscle into the defect or using a dermal substitute immediately under the skin. Facial nerve injury: This is an important risk of parotidectomy. It will manifest as inability to move all or part of your facial muscles on one side. The nerve injury can be partial if only some of the branches of the facial nerve are injured or total if the main trunk of the facial nerve or all branches of the facial nerve are injured.

We suspected a malignant tumor because of the associated facial nerve paralysis and parotid pain. On the contrary, we considered the possibility of a benign tumor with inflammation due to the reduction in tumor size and pain. We planned a total parotidectomy including exeresis and reconstruction of the facial nerve. However, we also made preparations to preserve the facial nerve should a benign tumor be suggested during the surgery. The patient underwent surgery at 31 days after the appearance of symptoms. A modified Blair incision was made, and a dumbbell-shaped parotid tumor, extending from the superficial to the deep lobe of the parotid gland, was identified. The buccal and marginal mandibular branches of facial nerve were pinched by the tumor Figure 3. The nerve branches were in contact with the tumor, but not involved. The temporal and zygomatic branches were present on the tumor capsule. A portion of the tumor was cut off and used for frozen section diagnosis FSD. It was found to consist of solid and cystic components. The solid component was surrounded by a fibrous capsule, and the wall of the cyst component was lined by a stratified squamous epithelium, which did not show any atypical changes. Based on the above results, we considered the tumor to be definitely benign. We managed to keep the facial nerve away from the tumor by use of microscissors, and the tumor was removed between the zygomatic and buccal branches. Histopathological examination showed the tumor contained clear cells, which formed a clear boundary between the normal parotid gland tissues Figure 4. The Ki labelling index was exceedingly low and the mitotic count was negative. These findings were consistent with oncocytoma of the parotid gland. Throughout the postoperative period, the nasalis muscle of the affected side was slightly weakened but it was completely recovered at 2 months after surgery. No recurrence was observed during the month follow-up period. Oncocytomas are benign neoplasms composed of oncocytes: Oncocytomas are rare, comprising only about 0. The parotid gland is the most common site of oncocytic changes [ 10 ], but they have also been noted in the submaxillary gland, sublingual gland, larynx, soft palate, hard palate, and nasal cavities. They often present as solitary slow growing painless masses, which are smooth and with some mobility upon clinical examination. Some oncocytomas consist of a curved nonenhanced lesion and cystic lesion, corresponding to central scar tissue and cystic degeneration, respectively.

A melanoma on the cheek with a positive sentinel node in level I would warrant removal of intervening lymph nodes via parotidectomy in the course of performing a neck dissection. A squamous cell carcinoma arising in the pre-auricular region with documented metastasis to level I would warrant an intervening parotidectomy. Parotid neoplasm management Pertinent anatomy The Parotid gland is a serous secreting gland, and the largest of the major salivary glands. It is located posterior and lateral to the mandibular ramus and anterior to the SCM. The posterior belly of the digastric and stylohyoid muscles lie deep to the gland. The gland is innervated by postganglionic parasympathetic fibers from the otic ganglion via the auriculotemporal nerve. The parotid duct extends from the anterior border of the gland, travels over the masseter muscle to penetrate the buccinator muscle and open into the oral cavity, adjacent to the second upper molar ipsilaterally. It is common to see accessory parotid glands distally along the parotid duct, and these are termed socia parotidis. The retromandibular vein is used as a landmark when evaluating imaging studies, as this vein marks the division of the deep and superficial lobes. This relationship is important as it approximates the depth of the facial nerve. This gland is encased in parotid fascia superficial layer of the deep cervical fascia.

Some technical terms related to the extent of the surgery: Superficial parotidectomy: The parotid gland is artificially divided into a superficial and deep lobe by the facial nerve that runs in a set plane in the middle of the gland. A superficial parotidectomy requires removal of the parotid gland superficial to the plane of the facial nerve. This is the most common type of parotid surgery. A less than complete superficial parotidectomy, but one that has still removed the entire tumor with negative margin, may also be referred to as a partial parotidectomy. Total parotidectomy: This requires removal of the entire parotid gland, including the superficial and deep lobe. If the facial nerve is not involved, this will require identifying all of the branches and carefully retracting them out of the way as meticulous dissection is performed.

Although the case is usually clean, the interruption and retention of salivary tissue may create an environment for bacterial sialadenitis to develop. As a result, we leave patients on antibiotics for 5 to 7 days converted to oral antibiotics once feeding is begun. Although not necessary for all cases, nasotracheal intubation through the nostril contralateral to the tumor may occasionally be preferred in selected cases. Do not paralyze patient we may employ a facial nerve stimulator. Head of bed is elevated to diminish bleeding. Flap elevation may be safely performed at a slightly deeper plane — just superior to periparotid fascia — to diminish risk of symptomatic Frey's syndrome by making a thicker skin flap. This parameter also allows the surgeon to reassure patients with postoperative FP about the likelihood of recovering facial function 2. From a forensic perspective, these data are interesting. A false positive signal is one that may result in the misrecognition of the facial nerve. False positive signals are most often encountered upon the distribution of electrical stimulation. Such signals should not occur with well-adjusted monitoring parameters unless the surgeon applies significant traction to the nerve. False negative signals are a concern because they can result in the non-recognition of the facial nerve. These signals can be explained by the persistence of a fibrous layer that is in contact with the nerve. This relationship emphasizes the importance of careful dissection of branches of the nerve downstream of the stimulation that have been damaged by the tumor, a surgical procedure or, less frequently, by improper adjustment of the parameters. In their series, Meier et al. They concluded that FNM is not a substitute for knowledge of the anatomy and careful dissection of the nerve during parotidectomies Witt et al. To prevent this problem, the surgeon should always maintain a critical approach to intervention and monitoring. This approach ensures that monitoring will be used efficiently and rationally. Some cases of transient lesions hematomas, muscle, and eye injuries have been described 2. Three cases of severe facial burns have been reported following the use of the FNM for parotidectomy. These burns resulted from technical defects in an earlier monitoring model that were likely caused by an electrolysis phenomenon The burns occurred at the level of the electrode insertion and the extent of the burns was related to the duration of monitoring. This phenomenon should not occur when current systems are used. Finally, the benefits of FNM offset the significantly higher risk of skin burns Monitoring requires an initial expense because a console must be purchased; however, this cost is offset quickly because the console will be used frequently during otological and thyroid surgery. There are also repeated costs for each intervention related to the use of disposable components including the electrodes. Terrell et al. Therefore, FNM is a useful and inexpensive aid for parotid surgery 4. FNM is a simple and effective adjunct method that is available to surgeons during parotid surgery to assist them with the functional preservation of the facial nerve. Our results indicate improved preservation of facial nerve function at one month and six months after reoperations that used FNM. However, FNM use did not improve the facial prognosis in first-line surgery cases. The utility of FNM for malignant and large tumors remains unproven. It would be interesting to continue our series with an increase in sample size and thus statistical power to allow the detection of differences among the different subgroups.

It does not improve the facial Parotidectomy and facial in routine procedures, regardless of whether they are superficial or total parotidectomies. Young surgeons are particularly likely to use FNM because they have been trained in this procedure and have little experience performing parotidectomies without FNM. FNM can be used for any parotidectomy independent of the histology, size, and location of the tumor 2.

However, no studies provide guidelines for its use 6. FNM allows younger surgeons to improve their technical skills more quickly Parotidectomy and facial allows experienced surgeons to develop and mentor junior surgeons more easily. The systematic use of FNM for all parotidectomies allows surgeons to become familiar with this tool.

Thus, during reoperations or surgeries involving large tumors that alter anatomical landmarks, the surgeon will have a high degree of confidence in Parotidectomy and facial use of FNM.

FNM makes it easier to recognize the facial nerve and its branches with minimal traumatic manipulation 24. The benefits of FNM use with routine procedures to treat benign tumors is controversial.

The most commonly used global House—Brackmann grading system GHB was developed to assess the paresis of the facial nerve after surgery of the ponto-cerebellar angle tumors [ 9 ]. Studies that use the House—Brackmann scale to describe parotidectomy injuries to the facial nerve may overlook paresis of isolated branches of the nerve. Therefore, the true incidence of the facial nerve paresis following parotidectomy in the literature is questioned given the inadequacies of the grading scales. Objective systems are based on measurements of the distance between certain points on photographs of the face BFLMI and its modifications—the Nottingham System , but these systems are time-consuming, complex, and not amenable to simple bedside examination [ 6 , 7 ]. Croxson et al. They could not prove whether one scale was superior to the other, because the former is a subjective and qualitative scale and the latter is an objective and quantitative scale. Although these scales attempt to improve the accurate description of damage to the facial nerve function, a universal scale is not agreed upon. Currently, there is a tendency to create automated functional assessment of the facial nerve. The disadvantages of this method are that it requires a normal side for comparison and standardization. The presence of some individual differences between left and right side of the face, for example strabismus, artificial eye or post-traumatic deformity, might also lead to difficulties in facial nerve grading [ 15 ]. Because objective scales are time-consuming and require complicated measurements, subjective scales are more commonly used at the bedside even though they are more prone to variability between raters. The five regions of the face and neck innervated by the 7th cranial nerve forehead, eye, cheek, mouth, neck and the degree of impairment of each region should be included in any new grading system. The more areas surveyed, the more detailed the scale becomes. However, it should be noted that the most important innervation deficits for patients involve the eye and mouth not the forehead, cheek, or neck. Only the Sydney scale assesses the cervical branch; however, inclusion of the cervical branch may obscure the impact of injury to more important branches of the nerve in their total assessment. The Sydney and DEFS scales only describe two degrees of paresis, which may be less accurate than other scales such as the regional House—Backmann scale that has four levels of paresis. However, scales such as the House—Brackmann scale that have a high range in scores may make it more difficult to compare patients [ 8 , 10 , 12 ]. Rickenmann et al. The five-step rating system that incorporates three degrees of paresis on the top of complete paralysis and full function outcomes seems to be the best compromise between accuracy and low complexity. Another problem is the smaller range of activities of the cheeks and forehead muscles, since their participation in spontaneous movements is less clear and the range of targeted motion harder to quantify. As already mentioned, the deficit of their activities is also less important, and perhaps for this area it would be beneficial to use only 2 degrees of paresis. The exact determination of facial nerve function is sometimes very difficult. The authors feel that in the setting of uncertainty, the score should be upscaled to indicate the worst-case scenario. Thus, in the presented scale, the authors did not include synkineses rated in Sunnybrook and Sydney scales [ 11 , 12 ]. As demonstrated by the statistical analysis of the facial nerve function, the results were consistent and highly correlated in all tested scales. In group 2, 19 facial palsies were noted; 12 were transient and 7 were definitive. At both one and six months after parotidectomy, the rate of facial palsy in reoperation cases was significantly higher in group 1 than in group 2. Facial nerve monitoring is a simple, effective adjunct method that is available to surgeons to assist with the functional preservation of the facial nerve during parotid surgery. Although it does not improve the facial prognosis in first-line surgery, it does improve the facial prognosis in reoperations. Facial nerve preservation in parotid surgery was first described in by Thomas Carwardine 1. It presents a major challenge given the risk of aesthetic and functional damage. The factors that increase this risk are large tumor size, deep location, malignancy, and reoperations 1 , 3. Facial nerve monitoring FNM was created in the early s 5. However, to our knowledge, there are limited data on the subject found in literature and there are no guidelines for clinical use 6. The benefits and indications of FNM remain to be defined. The aim of our study was to assess the use of FNM for the functional preservation of the facial nerve in parotidectomies. The study population was divided into the following two groups based on the use of facial nerve monitoring: Facial nerve monitoring was performed using the NIM-Response 2. All patients with an indication for parotidectomy were included in this study; they were examined by the ENT service preoperatively and reviewed postopera- tively. All of the patients were operated on by two senior surgeons. The primary endpoint was the House-Brackmann classification at one month and six months postoperatively. Facial palsy was considered definitive after 6 months. For patients with a partial dissection of the facial nerve, especially cases involving reoperation and partial FP, only total palsy of the involved territory was taken into account. We excluded from our study patients with minimal damage of a distal branch of the facial nerve. They were considered free of facial palsy. For patients with reoperation, the parotid was excised with complete nerve re-dissection. The size and location of the tumor, determined with MRI, and the final tumor histology were also recorded for each of the 2 groups. The differences were considered significant at a p-value less than or equal to 0. The hospital ethics committee exempted this study from the need for consent because it only involved retrieving data from medical records Scientific Committee for Clinical Trials of the Percy Hospital, September Overall, parotidectomies were performed on patients. The average tumor size was 3. The tumors were histologically benign in cases and malignant in 23 cases. There were 16 pleomorphic adenomas Partial or temporary facial nerve damage was seen in six patients at At 6 months follow-up, however, recovery was complete, and we had no permanent facial nerve damage. Of 17 patients, 10 None of our patients had an infection, permanent facial weakness, or tumor recurrence. However, it should be stressed that Goa is a small state and due to the small number of cases in the study, it could be labeled more as a personal one. Superficial parotidectomy is a safe operation if performed with attention to detail, meticulous gentle dissection and avoidance of direct trauma or stretches to the nerve to prevent facial weakness.

Mosby-Wolfe; Skin closure is done with or vicryl or chromic subcutaneous and combination of running and interrupted nylon to skin of the neck and nylon to the face. Pressure dressing is used until patient is awake, then removed if suction drain is used. A tighter mastoid-like dressing with wrap-around neck is used in conjunction with a Penrose drain. Suction drain management The suction drain is left in for 36 hours minimum longer depending on output. General rule: Remove drain only after three consecutive 8-hour shifts demonstrate less than 30 cc total output. The drain may be managed in an outpatient setting. Secure the drain by placing 2-inch cloth tape to the shoulder and taping the tubing to the cloth with 2 inch clear tape. After demonstrating proficiency with caring for the drain, the patient may be discharged on postoperative day 1 with a scheduled return appointment on postoperative day 6 for suture and drain removal.

Extra-temporal facial nerve injury: Submitted to Otolaryngol Head Neck Surg. Evaluation and surgical treatment of tumors of the salivary glands. Comprehensive Management of Head and Neck Tumors. Philadelphia, PA: WB Saunders; The national cancer data base report on cancer of the head and neck: Head Neck. To the best of our knowledge, we have found no previous similar study in the reviewed literature. The exclusion of doubtful data and the usage of measures obtained from high quality clinical and histopathological reports made the evaluation very precise and reliable. In this study, the surgeries were performed by residents under the strict supervision of a senior Head and Neck surgeon. This may be considered a bias of the study since more than one surgeon performed the surgeries; however, this fact reflects best the reality of most medical residence centers in Brazil. Intraoperative neural monitoring IONM was not routinely used due to hospital's limitation quota. Therefore, its use was reserved to recurrent tumors. Females were 56 cases, and males, Of the 14 patients with postoperative facial paralysis, 10 were females and four were males. No permanent lesions were reported, and all patients were fully recovered within 36 weeks. Transient facial palsy remains the most common complication in parotid gland tumor 14 and an important factor of distress both to patients and the surgical team. If the lesion is permanent the consequences are tremendous, resulting in possible cornea ulcers, facial asymmetry, dysphasia, and drooling. Superficial parotidectomy remains the most efficient technique yet available, allowing the surgeon through the complete facial nerve dissection, with better chances of preserving its function. It is still a matter of debate whether the incidence of facial paralysis is higher after malignant tumors resection, due to a more aggressive surgical approach, 23 or after benign lesions, usually with a longer duration of the disease, associated with tumor's adherence and adjacent inflammatory process. It is quite intuitive to relate the increase of tumor's dimension to a higher incidence of complications. In this study, we have demonstrated that tumors with 3. This should be taken into account in the pre-operative evaluation, and consequently, demand a much more careful technique during nerve dissection. All of the 16 cases of recurrence occurred after enucleation of the lesion performed elsewhere, since this approach is not preconized at our institution. As seen in this study, the secondary surgery has a much higher risk of resulting in facial palsy, surely due to perilesional inflammation, fibrosis and lack of anatomical landmarks. Surgery performed after a previous approach of the parotid gland has an odds ratio of 6. This should be recognized when performing the primary surgery, demanding a curative approach to avoid a secondary and, therefore, more risky surgery and during the secondary surgery itself, since the risks of facial nerve injury are significantly higher. On the other hand, duration of the disease had no correlation with a higher risk of facial nerve injury during superficial parotidectomy. The calculated odds ratios were 1. Parotidectomy is the removal of part or all of the parotid gland on one side of the face. Understanding the anatomy of the facial nerve as it relates to the parotid gland is key to understanding the surgery. In some cases, additional procedures might be done at the same time as the parotidectomy. For example, a neck dissection might be indicated in certain types of parotid cancer, a facial nerve graft might be done if part or all of the facial nerve has to be sacrificed or a temporal bone resection might be required if the parotid cancer is growing into the side of the head where the ear is located. Your doctor should tell you about these associated procedures prior to surgery. Your doctor and care team will let you know what you need to do to prepare for surgery. In general, you should not eat or drink anything except essential medications anytime after midnight prior to surgery. Your doctor will give you a medical clearance evaluation and give recommendations to optimize all the other organs in your body prior to undergoing general anesthesia and surgery. On the day of surgery, you will need to arrive at the hospital or surgery center a few hours before the scheduled operation. This allows the nurses and anesthesiologist to confirm everything is in order for you to have as safe a surgery as possible. You will see your surgeon one last time before receiving the anesthesia and falling asleep, and you can ask any last-minute questions at that time. In some cases, your surgeon might choose to use a special monitor that makes a noise when the facial nerve including certain branches is stimulated. A parotidectomy is done via an incision just in front of the ear in a natural skin crease that extends down into a natural skin crease in the neck. This allows your surgeon to hide the scar as much as possible rather than making an incision directly in the middle of your face..

Patients who have had any kind of facial motricity impairment previous Parotidectomy and facial surgery were also excluded. During the studied period patients were submitted to surgical approach in the parotid gland; were due to pleomorphic adenoma.

The recovery course will depend on the extent of any additional surgery and reconstruction. With a parotidectomy alone, you should be ready Parotidectomy and facial go home the same day, the next day or, at most, two to three days later.

The authors feel that in the setting of uncertainty, the score should be upscaled to indicate the worst-case scenario. Thus, in the presented scale, the authors did not include Parotidectomy and facial rated in Sunnybrook and Sydney scales [ 11Parotidectomy and facial ].

As demonstrated Parotidectomy and facial the statistical analysis of the facial nerve function, the results were consistent and highly correlated in all tested scales. The advantages of new scale is also its possibility of a precise Parotidectomy and facial of the facial nerve function in an individual patient, as well as the presentation of mean values and the degree of paresis of the nerve branches in the entire group of patients.

The disadvantage of the scale is its subjectivity, the difficulty in grading the temporal and buccal branches paresis Parotidectomy and facial forehead and cheek movements and the presence of a fraction of Parotidectomy and facial average values for a group of patients with paresis. The postoperative facial nerve dysfunction is not only a please click for source problem, but a functional problem as well.

Depending on locations of the injuries to the nerve trunk or branches, important functions such as facial expression, eye protection, eating, drinking, and speech can be affected. This is why it is necessary to use an appropriate scale to measure all aspects of the facial nerve function.

Although this scale can be used to compare outcomes complicationsit may also be applicable in legal proceedings, insurance compensationsand rehabilitation outcomes.

Methods Facial nerve grading systems review The following scales were analyzed for the assessment of the facial nerve function after Parotidectomy and facial Creation of the own facial nerve grading system Based on these scales, the authors decided to create their own system taking into account specifics Parotidectomy and facial the facial nerve dysfunction in patients after parotidectomy.

Close up pussy porno. Dysfunction of the facial nerve is a common complication of parotidectomy. The functional deficit may be total or partial, and may include all or a single branch of the nerve.

Despite a wide variety of the facial nerve grading systems, most of them have a limited utility in patients after parotidectomy. Therefore, existing scales assessing facial nerve function Parotidectomy and facial compared to describe facial nerve outcomes after parotidectomy. The regional House—Brackmann, Sydney, and Yanagihara classification systems were utilized. The post-parotidectomy facial nerve grading system PPFNGS was created based on these three grading systems and also Parotidectomy and facial for this study.

The facial nerve function was assessed and recorded on the first postoperative day following conservative parotidectomy in patients using all 4 scales by 3 otolaryngologists.

Parotidectomy and facial

The validity of the PPFNGS and existing facial nerve grading systems was examined by assessment of interrater agreement, intraclass correlation coefficient, Parotidectomy and facial consistency Parotidectomy and facial construct validity. Although results were consistent in all tested scales, the PPFNGS had a higher interrater agreement than the other three scales. PPFNGS is a new grading system designed for assessing Parotidectomy and facial facial nerve function after parotidectomy in a quantitative and qualitative way and has a higher interrater agreement than other scales used to examine function of the 7th nerve.

The online version of this article doi: Parotidectomy is a well recognized and common surgical procedure used to treat tumors in the parotid Parotidectomy and facial. Dysfunction of the facial nerve is a common and typical complication of this surgical technique even though its anatomic continuity is preserved [ 1 ]. The deficit of the nerve function may be total paralysis or partial Parotidectomy and facialand see more injury to the main trunk or only the individual branches.

According to data from the world literature, postoperative transient facial nerve dysfunction Parotidectomy and facial up Parotidectomy and facial Dysfunction of the 7th nerve occurs most frequently to the marginal mandibular branch— Apart from the cosmetic defect facial contortionthe most troublesome for the patient are paresis of the zygomatic branch inability to close the eye completely and corneal drying and the marginal mandibular branch difficulty in eating, drinking, and speaking.

Paresis or paralysis of the cervical branch is negligible [ 4 ]. Only a few publications describe the branches involved. Therefore, the authors decided to review the existing scales assessing function of the facial nerve in relation to their use in patients after parotidectomy. The following scales were analyzed for the assessment of the facial nerve function after parotidectomy: Because the function of the entire facial nerve and its individual branches is desired quantitative and qualitativethe authors rejected the scales showing only the global quantitative function of the facial nerve which are the Adour and Swanson System, BFLMI, DEFS, global House—Brackmann, Sunnybrook and the Nottingham System.

The Sydney facial grading system evaluates function of the five facial nerve branches including the cervical branch for the targeted movements of the facial muscles Parotidectomy and facial supplied by these branches, giving each from 0 to 3 points, and the result is presented with the points 0—3 granted for synkineses [ 12 ].

The regional modification to the House—Brackmann scale assesses four facial regions at rest and during movements forehead, eye, midface, and mouthawarding from 1 to 6 points 1, normal; 6, paralysis [ 10 ]. As used in Japan, the Yanagihara grading system investigates different facial muscles at rest and during 9 separate actions, giving points from 0 to 4.

The total score ranged from 0 complete paralysis to 40 full function. Most of the functions being examined concerns the eye 4 and mouth 3which reflect isolated paresis, but this scale does not provide a qualitative deficit of individual branches of the facial nerve [ 13 ].

Regional House—Brackmann, Sydney and Yanagihara facial Parotidectomy and facial grading systems were presented in electronic supplementary material. Based on these scales, the authors decided to create their own system taking into account specifics of the facial nerve dysfunction in patients after parotidectomy.

This scale examines read more function of four branches of the facial Parotidectomy and facial and it was based on the evaluation of facial symmetry at rest, during spontaneous blinking, talking, smiling and voluntary movements of the facial muscles forehead, eye, cheek, mouth by performing the following steps: Activity was evaluated by giving to the each branch of the facial nerve from 0 to 4 points.

Full symmetry at rest with full movements—4 points complete functionsymmetry at rest with a slight asymmetry with complete movements—3 points slight paresissymmetry at rest with a clear asymmetry with movements—2 points pronounced paresisasymmetry at rest with a trace of movement—1 point profound paresisand asymmetry in the rest of the complete lack of mobility—0 points Parotidectomy and facial of all branches.

Slight paresis represents Parotidectomy and facial symmetry at rest, but only a slight asymmetry of facial function Parotidectomy and facial motion. This form of paresis does not interfere with complete eye closure, puckering of the lips to whistle or smile, or raising of the eyebrows.

Pronounced Parotidectomy and facial represents normal symmetry at rest, but obvious asymmetry with motion that also interferes with function, such as inability to close the eye completely. To assess the qualitative presentation of facial paresis, a score from 0 to 4 was given to measure the function of each facial nerve branch T, temporal; Z, zygomatic; B, buccal; M, Parotidectomy and facial mandibular. For example, full function of all four branches is scored as 16 T4, Z4, B4, M4.

Slight paresis 3 points of only marginal mandibular branch Parotidectomy and facial scored as 15 T4, Z4, B4, M3. Profound paresis 1 point of the temporal branch and pronounced paresis 2 points of the click branch is scored as 11 T1, Z2, B4, M4. Paralysis of all branches 0 points is Parotidectomy and facial a score 0 T0, Z0, B0, M0. The average score for global facial assessment in the sample group is In our new scale the synkinesis and mass contracture were not taken into consideration; however, there is a potential possibility to present these abnormalities by adding the letter S while recording the nerve function, for example 12S T2S, Z2S, B3, M3.

Validity of the new and the selected existing functional facial nerve grading systems was examined by assessment of interrater agreement, intraclass correlation coefficient, internal consistency and construct validity.

Interrater agreement was assessed using the weighted kappa-statistic for three raters. The remaining part of the total variance reflects the inter-observer variance. Agreement between the new Parotidectomy and facial and the existing ones was assessed Parotidectomy and facial Bland—Altman method with regression adjustment for the proportional bias.

The marginal mandibular branch was involved in 29 patients, the temporal in 4 patients, temporal and zygomatic in 4 other patients, and all branches in 17 patients.

In the remaining patients who underwent surgery, according to Parotidectomy and facial the examining specialists, the facial nerve function was unaffected. The recorded function of the facial nerve in the investigated group in four tested systems assessed by one observer.

Patient with right-sided post-parotidectomy facial nerve paresis: The recorded function of the just click for source nerve of the patient from the figure in four tested systems assessed by one observer.

Parotidectomy and facial 0. Adequate assessment of the facial nerve function after parotidectomy requires attention to the individual facial nerve branch deficits Parotidectomy and facial their degree of function. The most appropriate scale should be able to allow evaluation of the degree of damage to the individual branches of the Parotidectomy and facial nerve in a quick and reproducible manner that is not cumbersome.

The existing grading systems to measure the function of the facial nerve can be described as global and regional, as well as subjective and objective. The most commonly used global House—Brackmann grading system GHB was developed to assess the paresis of the facial nerve after surgery of the ponto-cerebellar angle tumors [ 9 ]. Studies that use read more House—Brackmann scale to describe parotidectomy injuries to the facial nerve may overlook paresis of isolated branches of the nerve.

It will manifest as a fluid-filled swelling somewhere near the surgical site and get bigger with eating. Treatment can include doing nothing, applying a pressure dressing or repeated aspirations to draw off the saliva. Sensory disturbance: A decrease in sensation of skin of the neck, around the face and the lobule occur when the greater auricular nerve or some of its branches are cut. This is required in most parotidectomy procedures. Over time, the area of numbness will shrink, but the lobule of the ear will probably remain numb forever. This occurs because after removing the parotid gland, the nerve endings that normally stimulate saliva production and secretion from the auriculotemporal nerve end up against the skin now that the parotid gland is gone. Because the same neurotransmitter that stimulates salivary release also stimulates sweating, whenever that nerve is activated, it causes sweating instead of salivary release. The severity of this problem can vary from not even noticeable to very severe and troublesome. Treatment options include applying anti-perspirant to the facial skin, injecting botulinum toxin Botox in that region of the skin which blocks the neurotransmitter that causes sweating , surgery to place a barrier just under skin or extensive middle ear surgery to cut the nerve that causes all of these problems near its origin. One way to prevent this complication is to place a barrier between the free nerve endings and the skin at the time of the parotidectomy itself. This barrier can be in the form of sewing the parotid fascia back together thereby covering up those free nerve endings , moving muscle into the defect or using a dermal substitute immediately under the skin. Facial nerve injury: This is an important risk of parotidectomy. It will manifest as inability to move all or part of your facial muscles on one side. The nerve injury can be partial if only some of the branches of the facial nerve are injured or total if the main trunk of the facial nerve or all branches of the facial nerve are injured. It can be temporary if the nerve is just stretched or permanent if the nerve is cut. The mass was identified between the inferior and superior divisions. The facial nerve branches around the tumor were dissected out past the mass so that the tumor could be peeled away from the facial nerve. In this fashion the mass was completely removed along with a cuff of normal-appearing parotid tissue on all sides with grossly negative margins. The mass was then oriented and sent to pathology. Frozen sections were obtained and indicated pleomorphic adenoma. The main trunk of the facial nerve was stimulated and caused contraction of all facial muscles supplied by the nerve. Bleeding was stopped with bipolar cautery and the wound was irrigated with sterile saline. A fully perforated soft-flat Jackson Pratt drain was then placed in the surgical bed and the wound closed in layers using Vicryl sutures to reapproximate subcutaneous tissue and and running nylon stitches to reapproximate the skin. The patient tolerated the procedure well, was extubated in the operating room and transferred uneventfully to the post anesthesia care unit. Skip to main content. Parotidectomy with Facial Nerve Dissection last modified on: Salivary Gland Surgery Protocols see also video: Shaw Hemostatic Scalp for Parotidectomy Case examples: The presence of an unexplained mass in the parotid gland warrants consideration for parotidectomy to be done both for diagnosis and treatment. A melanoma on the cheek with a positive sentinel node in level I would warrant removal of intervening lymph nodes via parotidectomy in the course of performing a neck dissection. A squamous cell carcinoma arising in the pre-auricular region with documented metastasis to level I would warrant an intervening parotidectomy. Parotid neoplasm management Pertinent anatomy The Parotid gland is a serous secreting gland, and the largest of the major salivary glands. It is located posterior and lateral to the mandibular ramus and anterior to the SCM. The posterior belly of the digastric and stylohyoid muscles lie deep to the gland. The gland is innervated by postganglionic parasympathetic fibers from the otic ganglion via the auriculotemporal nerve. The parotid duct extends from the anterior border of the gland, travels over the masseter muscle to penetrate the buccinator muscle and open into the oral cavity, adjacent to the second upper molar ipsilaterally. It is common to see accessory parotid glands distally along the parotid duct, and these are termed socia parotidis. The retromandibular vein is used as a landmark when evaluating imaging studies, as this vein marks the division of the deep and superficial lobes. This relationship is important as it approximates the depth of the facial nerve. This gland is encased in parotid fascia superficial layer of the deep cervical fascia. Consideration for more aggressive behaving masses: If there is a suspicion that the facial nerve may need to be sacrificed, be prepared for primary nerve or cable graft repair with great auricular, sural, or accessory nerve if removed in neck dissection. Describe potential for neck dissection if final specimen at time of surgery shows intermediate or high-grade malignancy. Neck dissection may range in scope from removal of upper Level I and II nodes as accessed through Blair incision to possible radical neck dissection if metastatic disease seen at time of surgery.

Therefore, the true incidence of the facial nerve paresis following parotidectomy in the literature is questioned given the inadequacies of the grading scales. Objective systems are based on measurements of the distance between certain points on photographs of Parotidectomy and facial face BFLMI and its modifications—the Nottingham Systembut these systems Parotidectomy and facial time-consuming, complex, and not amenable to simple bedside examination [ 67 ].

Parotidectomy and facial

Croxson et al. They could not prove whether one scale was superior to the other, because the former is a subjective and qualitative scale and the latter is an objective and quantitative scale. Although these scales attempt to improve the accurate description of Parotidectomy and facial to the facial nerve function, a universal scale is not agreed upon.

Currently, there is a tendency to create automated functional assessment of the facial nerve. The disadvantages of this method are that it requires a normal side for learn more here and standardization. The presence of some individual differences between left and right side of the face, for example strabismus, artificial eye or post-traumatic deformity, might also lead to difficulties in facial nerve grading [ 15 ]. Because objective scales are time-consuming and require complicated measurements, subjective scales are more commonly used at the bedside even though they are more prone to variability between raters.

The five regions of the face and neck innervated by the 7th Parotidectomy and facial nerve forehead, eye, cheek, mouth, neck and the degree of impairment of each region should be included in any new Parotidectomy and facial system. The more Parotidectomy and facial surveyed, the more detailed the scale becomes. However, Parotidectomy and facial should be noted that the most important innervation deficits Parotidectomy and facial patients involve the eye and mouth not the forehead, cheek, or neck.

Only the Sydney scale assesses the cervical Parotidectomy and facial however, inclusion of the cervical branch may obscure the impact of injury to more important branches of the nerve in their total assessment.

The Sydney and DEFS scales only describe two degrees of paresis, which may be less accurate than other scales such as the regional House—Backmann scale that has four levels of paresis. However, scales such as the House—Brackmann scale that have a high range in scores may make it more difficult to compare patients [ 81012 ].

Rickenmann et al.

Parotidectomy is the removal of part or all of the parotid gland on one side of the face.

The five-step rating system that incorporates three degrees of paresis on the top of complete paralysis and full function Parotidectomy and facial seems to be Parotidectomy and facial best compromise Parotidectomy and facial accuracy and low complexity. Another problem is the smaller range of activities of the cheeks and forehead muscles, since their participation in spontaneous movements is less clear and the range of targeted motion harder to quantify.

As read more mentioned, the deficit of their activities is also less important, and perhaps for this area it would be beneficial to use only 2 degrees of paresis.

The exact determination of facial nerve function is sometimes very difficult. The authors feel that in the setting of uncertainty, the score should be upscaled to indicate the worst-case scenario. Thus, in the presented scale, the authors did not include synkineses rated in Sunnybrook and Sydney scales [ 1112 ].

Case Reports in Otolaryngology

As demonstrated Parotidectomy and facial the statistical analysis of the facial nerve function, the results were consistent and highly correlated in all tested scales. The advantages Parotidectomy and facial new scale is link its possibility of Link precise description of the facial nerve function in an individual patient, as well as the presentation of mean values and the degree of paresis of the nerve branches in the entire group of patients.

The disadvantage of the scale is its subjectivity, the difficulty in grading the temporal and buccal branches paresis and forehead and cheek movements and the presence of a fraction of the average values for a group of patients with paresis. The postoperative facial nerve dysfunction is not only a cosmetic problem, but a functional problem as well. Depending on locations of the injuries to the nerve trunk or branches, important functions such as facial expression, eye protection, eating, drinking, and speech can be affected.

This is why it is necessary to use an appropriate scale to measure all aspects of the facial nerve function. Although this scale can be used to compare outcomes complicationsit may also be applicable in legal proceedings, insurance compensationsand rehabilitation outcomes.

Parotid gland tumor with facial nerve paralysis is strongly suggestive of a malignant tumor. However, several case reports have documented benign tumors of the parotid gland with facial nerve paralysis. Here, we report a case of oncocytoma of the parotid gland with facial nerve paralysis. A year-old male presented with pain in his right parotid gland. Physical examination demonstrated the presence of a right parotid gland tumor and ipsilateral facial nerve paralysis of House—Brackmann HB grade III. Due to the facial nerve paralysis, a malignant tumor of the parotid gland was suspected and right parotidectomy was performed. Oncocytoma was confirmed histopathologically. The facial nerve paralysis was resolved 2 months after surgery. During the follow-up period one and a half years , no recurrence was observed. As the tumor showed a distinctive dumbbell shape and increased somewhat due to inflammation i. Ischemia and strangulation of the nerve were considered to be the cause of the facial nerve paralysis associated with the benign tumor in this case. Parotid tumor with facial nerve paralysis is generally considered as a criterion for malignancy. Oncocytomas are rare benign tumors that comprise about 0. We herein describe the case of a year-old male who suffered from right parotid oncocytoma with facial nerve paralysis. A year-old male had been aware of a right parotid mass for about 10 years; however, he did not seek treatment as the mass was painless. On experiencing serious right parotid pain, he visited our affiliated hospital. Computed tomography CT revealed an enhanced irregularly shaped mass in the right parotid gland Figure 1 a. T1-weighted SE MR imaging of the mass showed lower intensity than that of the native parotid tissue Figure 2 a. T2-weighted SE MR imaging also showed intermediate signal intensity and partial hyperintensity Figure 2 b. At this stage, a malignant neoplasm of the parotid gland was suspected. Nine days after the appearance of symptoms, he was referred to our hospital. On physical examination, the mass was found to be still present but the pain had eased. In addition, the facial nerve palsy showed some improvement to HB grade II. Superficial parotidectomy: The parotid gland is artificially divided into a superficial and deep lobe by the facial nerve that runs in a set plane in the middle of the gland. A superficial parotidectomy requires removal of the parotid gland superficial to the plane of the facial nerve. This is the most common type of parotid surgery. A less than complete superficial parotidectomy, but one that has still removed the entire tumor with negative margin, may also be referred to as a partial parotidectomy. Total parotidectomy: This requires removal of the entire parotid gland, including the superficial and deep lobe. If the facial nerve is not involved, this will require identifying all of the branches and carefully retracting them out of the way as meticulous dissection is performed. Radical parotidectomy: This procedure is a total parotidectomy, along with resection of the facial nerve. An extended radical parotidectomy will involve removal of additional structures as well, such as the temporal bone or the skin of face overlying the parotid gland.

This phenomenon should not occur when current systems are used. Finally, the benefits of FNM offset the significantly higher risk of skin burns Monitoring requires an initial expense because a console must be purchased; however, this cost is offset quickly because the console will be used frequently during otological and thyroid surgery. There are also repeated costs for each intervention related to the use of disposable components including the electrodes. Terrell et al. Therefore, FNM is a useful and inexpensive aid for parotid surgery 4. FNM is a simple and effective adjunct method that is available to surgeons during parotid surgery to assist them with the functional preservation of the facial nerve. Our results indicate improved preservation of facial nerve function at one month and six months after reoperations that used FNM. However, FNM use did not improve the facial prognosis in first-line surgery cases. The utility of FNM for malignant and large tumors remains unproven. It would be interesting to continue our series with an increase in sample size and thus statistical power to allow the detection of differences among the different subgroups.

Abstract Introduction: Materials and Methods: Key Words: Introduction Facial nerve preservation in parotid surgery was first described in by Thomas Carwardine 1. Results Overall, parotidectomies were performed on patients. Only a few publications describe the branches involved. Therefore, the authors decided to review the existing scales assessing function of the facial nerve in relation to their use in patients after parotidectomy. The following scales were analyzed for the assessment of the facial nerve function after parotidectomy: Because the function of the entire facial nerve and its individual branches is desired quantitative and qualitative , the authors rejected the scales showing only the global quantitative function of the facial nerve which are the Adour and Swanson System, BFLMI, DEFS, global House—Brackmann, Sunnybrook and the Nottingham System. The Sydney facial grading system evaluates function of the five facial nerve branches including the cervical branch for the targeted movements of the facial muscles groups supplied by these branches, giving each from 0 to 3 points, and the result is presented with the points 0—3 granted for synkineses [ 12 ]. The regional modification to the House—Brackmann scale assesses four facial regions at rest and during movements forehead, eye, midface, and mouth , awarding from 1 to 6 points 1, normal; 6, paralysis [ 10 ]. As used in Japan, the Yanagihara grading system investigates different facial muscles at rest and during 9 separate actions, giving points from 0 to 4. The total score ranged from 0 complete paralysis to 40 full function. Most of the functions being examined concerns the eye 4 and mouth 3 , which reflect isolated paresis, but this scale does not provide a qualitative deficit of individual branches of the facial nerve [ 13 ]. Regional House—Brackmann, Sydney and Yanagihara facial nerve grading systems were presented in electronic supplementary material. Based on these scales, the authors decided to create their own system taking into account specifics of the facial nerve dysfunction in patients after parotidectomy. This scale examines the function of four branches of the facial nerve and it was based on the evaluation of facial symmetry at rest, during spontaneous blinking, talking, smiling and voluntary movements of the facial muscles forehead, eye, cheek, mouth by performing the following steps: Activity was evaluated by giving to the each branch of the facial nerve from 0 to 4 points. Full symmetry at rest with full movements—4 points complete function , symmetry at rest with a slight asymmetry with complete movements—3 points slight paresis , symmetry at rest with a clear asymmetry with movements—2 points pronounced paresis , asymmetry at rest with a trace of movement—1 point profound paresis , and asymmetry in the rest of the complete lack of mobility—0 points paralysis of all branches. Slight paresis represents normal symmetry at rest, but only a slight asymmetry of facial function with motion. This form of paresis does not interfere with complete eye closure, puckering of the lips to whistle or smile, or raising of the eyebrows. Pronounced paresis represents normal symmetry at rest, but obvious asymmetry with motion that also interferes with function, such as inability to close the eye completely. To assess the qualitative presentation of facial paresis, a score from 0 to 4 was given to measure the function of each facial nerve branch T, temporal; Z, zygomatic; B, buccal; M, marginal mandibular. For example, full function of all four branches is scored as 16 T4, Z4, B4, M4. Slight paresis 3 points of only marginal mandibular branch is scored as 15 T4, Z4, B4, M3. Profound paresis 1 point of the temporal branch and pronounced paresis 2 points of the zygomatic branch is scored as 11 T1, Z2, B4, M4. Paralysis of all branches 0 points is given a score 0 T0, Z0, B0, M0. The average score for global facial assessment in the sample group is In our new scale the synkinesis and mass contracture were not taken into consideration; however, there is a potential possibility to present these abnormalities by adding the letter S while recording the nerve function, for example 12S T2S, Z2S, B3, M3. Validity of the new and the selected existing functional facial nerve grading systems was examined by assessment of interrater agreement, intraclass correlation coefficient, internal consistency and construct validity..
