Facial nerve schwannomas (FNS) are encapsulated benign tumors arising from Schwann cells of seventh cranial nerve. Most of the facial nerve schwannomas are localized in intratemporal region; only 9% of cases involve a portion of the extratemporal segment. Preoperative diagnosis is often unclear; diagnosis is often made intraoperatively. Management of intraparotid FNS is troublesome because of the facial nerve paralysis. In this report we presented a case of intraparotid schwannoma in a 55-year-old male patient complaining of a painless mass without peripheral facial nerve palsy in left parotid gland. Clinical features, preoperative and intraoperative diagnosis, and difficulties during management are discussed with the review of the literature.

Parotid Gland Tumor

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 61-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.e., infection), the facial nerve was pinched by the enlarged tumor. 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.

Nerve Of Origin

Extracranial schwannomas in the head and neck region are relatively rare neoplasms. The tumours are slow growing and often unnoticeable. The nerve of origin is unable to be determined until the time of surgery. Proper preoperative assessment of the disease can be done by imaging studies such as magnetic resonance imaging. The treatment for these tumours is surgical resection with preservation of the neural pathway. We report a case of left intraparotid facial nerve schwannoma in a middle-aged lady causing complete facial nerve paralysis. The clinical features, diagnostic possibilities and management are discussedBangladesh Journal of Medical Science Vol.17(4) 2018 p.680-682

AbstractAn oncocytic mucoepidermoid carcinoma and an oncocytic pleomorphic adenoma occurred in a 47-year-old male and a 75-year-old female, respectively. Both presented as asymptomatic parotid gland masses without evidence of facial nerve paralysis and were treated by superficial parotidectomy. There has been no evidence of recurrence or metastasis. Oncocytic change is rare in major salivary gland mucoepidermoid carcinoma with only two previously reported cases. Marked oncocytic transformation of pleomorphic adenomas can cause their confusion with oncocytomas. Recognition of oncocytic differentiation in various salivary gland tumours is important to avoid misclassification of these lesions.

A Prospective Study

BACKGROUND: Bell's palsy is an acute weakness of seventh cranial nerve leading to loss of movement on one side of the face. It usually recovers of its own without treatment in most of the patients but not all. Physical therapy in the form of electrotherapy, massage and facial exercises is used as adjuvant to hasten recovery. OBJECTIVES: To analyze the role of physiotherapy in the form of electrotherapy in patients with peripheral facial paralysis attending multispecialty hospital in Kashmir. METHODS: A prospective study was carried out on 50 patients of facial nerve paralysis attending OPD between Jan 2009 and Jan 2010. All of the patients were subjected to medical treatment. The patients were put to Physical Therapy in the form of electrotherapy followed by facial exercises. All patients received electrotherapy to the paralyzed facial muscles for a period of 2 weeks but some were given extended doses for 4 weeks. 20 patients presented for the treatment in the first week, 12 in second week and 18 presented after three weeks or later. RESULTS: Fifty patients (30 female, 20 male) of facial nerve paralysis were included. Time span between medical diagnosis and physical therapy was from 1 week to 4 weeks. Patients were assessed at 4 weeks, 2 months and 6 months after the treatment. Out of 20 patients who presented in 1st week and received steroids and electrotherapy 19(95%) had fully recovered except for one case that was irregular for treatment. Out of 12 Patients who presented in 2nd week of illness, 8(66.6%) patients had full recovery and partial recovery in rest of 4 (33.4%) patients. Eighteen patients (100%) who presented in third week onwards of illness had partial recovery. CONCLUSION: Physiotherapy in the form of electrotherapy and facial exercises has a effective role in the early management of peripheral facial palarlysis. JMS 2012;15(2):145-48

Facial Nerve Schwannoma

<p class="abstract"><span lang="EN-IN">Schwannoma is a benign tumor arising from Schwann cells which is protective covering of nerves, called myelin sheath and can develop anywhere, where Schwann cells are present. Most common schwannomas are found with vestibulocochlear nerve. Facial nerve schwannoma are uncommon tumour involving 7th nerve out of which also most common site of involvement is geniculate ganglion. Facial nerve schwannoma is uncommon benign tumor. There are no typical patterns of presentation and can easily go untreated or misdiagnosed. Facial nerve palsy is most common mode of presentation. Here we present a case of 35 years male who presented with complaint of facial nerve paralysis. High degree of clinical suspicion and early imaging can lead to diagnosis. An early diagnosis is important as morbidity associated with this disease and as well as surgery leads to delay in diagnosis.</span></p>

Accessory Parotid Gland

Purpose: The head and neck surgeon’s fascination with parotid surgery arises from the gland’s spectrum of histopathological presentations, as well as the diversity of its morphological features. A mass arising in the mid-cheek region may often be overlooked as a rare accessory lobe parotid neoplasm. This report serves to revisit the topic of accessory parotid gland neoplasms to emphasize proper management, particularly the surgical aspects, so that consequences of salivary fistula, facial nerve paralysis, and recurrence are avoided. Case report: We report a case of mucoepidermoid carcinoma which was assessed pre-operatively as arising from the accessory parotid gland of a 11-year-old female. She had complained of a painless and round mass of the left cheek for a duration of 12 months. Sialography, ultrasonography, CT scan and MRI were performed preoperatively. Sialography revealed a small duct separating from the Stensen’s duct. CT and MRI showed that the tumor with smooth outline was lying on the masseter muscle and detached from the main parotid gland. The preoperative diagnosis was an accessory parotid gland tumor. The tumor was removed without facial nerve injury via standard parotidectomy incision. The tumor was composed of mucous, intermediate and epidermoid cells. The pathological diagnosis was low-grade mucoepidermoid carcinoma. Conclusions: Accessory parotid gland neoplasms are rare and may present as innocuous extraparotid mid-cheek masses. A high index of suspicion, prudent diagnostic skills (including fine-needle aspiration [FNA] biopsy followed by computed tomography [CT] imaging), and scrupulous surgical approach (extended parotidectomy-style incision and limited peripheral nerve dissection when possible) are the keys to successful management of these lesions.
