Pleomorphic Adenoma Arising from Accessory Parotid Tissue Presenting as Dysphonia

Management of accessory parotid gland tumours: 32-year experience from a single institution and review of the literature

Accessory parotid gland tumours (APGTs) are very rare. Regarding their anatomical location, an adequate surgical approach is necessary to provide safe resection and satisfactory postoperative results. The aims of this study were to present our tertiary centre experience in surgical treatment and management of APGTs and to review the literature regarding their treatment, particularly in terms of surgical modalities. Data of 13 patients with primarily surgically treated APGTs have been collected and analysed. Well-documented English-literature articles of surgically treated APGTs have been extracted from the PubMed, Scopus and Web of Science databases ending in May 2018, and analysed. Mean age at diagnosis was 41.1 years. The most common benign histological subtype was pleomorphic adenoma (53.8%), while mucoepidermoid carcinoma (23.1%) was most common in malignant counterparts. The malignancy rate was 38.5%. Postoperative results were satisfactory, and the follow-up period was uneventful in all patients except one who died of locoregional recurrence. A total of 57 papers with reported series in APGTs have been identified with a total of 306 APGT cases. From oncological, functional and aesthetic standpoints, approaches through a standard parotidectomy provide satisfactory results.

Clinical management of masses arising from the accessory parotid gland

OBJECTIVE

Accessory parotid lesions are clinically rare and its management remains poorly understood. The aim of this study was to analyze the clinical management of accessory parotid lesions.

STUDY DESIGN

From April 1999 to November 2008, a retrospective analysis of 32 patients with accessory parotid lesions was performed. The preoperative examinations, surgical treatment, and prognosis were recorded and analyzed.

RESULTS

Among the 32 patients, there were 8 men and 24 women with an overall average age of 45 years. These patients always presented without obvious symptoms, and the masses were moderate to hard in hardness without tenderness, mobile, and with clear boundary. The pathologic diagnoses were 24 benign and 8 malignant lesions. Surgery and surgery plus radiotherapy were performed in the patients with benign and malignant lesions, respectively, with good prognosis.

CONCLUSIONS

Accessory parotid lesions are rare, and the clinical manifestation is always the same for benign tumors. Surgical resection and surgical resection plus radiotherapy are the primary choices of treatment for benign and malignant lesions, respectively. The prognosis is always good.
