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.

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.

Objective: Facial nerve paralysis is one of the most devastating complications after parotid gland surgery. We aimed to determine the prevalence and risk factors of facial palsy after parotidectomy.Methods: We performed a retrospective review of the data from 54 patients who underwent parotid surgery between 2004 and 2015 at a tertiary medical care center. The prevalence of facial nerve paralysis and possible risk factors (demographic characteristics, tumor characteristics, and operative factors) associated with postoperative paralysis were assessed. Categorical variables were evaluated using the Fisher’s exact test, and a two-tailed t-test was used to assess the associations between continuous and binary outcome variables.Results: The postparotidectomy prevalence of temporary and permanent facial nerve paralysis were 26% and 13%, respectively. Tumors involving both lobes were significantly associated with permanent facial nerve paralysis (p = .048). Long operative duration (> 164 minutes) was associated with both temporary and permanent facial nerve paralysis (p = .040).Conclusions: Operative factors such as operative duration and tumor characteristics such as bilobal involvement increased the risk of postparotidectomy facial nerve paralysis. Such factors should be considered to reduce the risk of palsy in patients undergoing parotidectomy.

Left Parotid Gland

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.
