Endoscope-assisted transoral accessory parotid mass excision.

Abstract

Accessory parotid gland tissue is salivary tissue adjacent to Stensen's duct that is distinctly separate from the main body of the parotid gland. Surgical removal of an accessory parotid mass is usually accomplished through an external neck incision. However, this procedure inevitably results in a neck scar. We report the case of a 55-year-old man with an accessory parotid mass. We applied a modified approach to accessory parotid mass removal through the mouth with an endoscope system. The patient, who was diagnosed with a benign pleomorphic adenoma, underwent endoscope-assisted transoral accessory parotid mass excision. The follow-up time was 6 months. The patient experienced no serious postoperative complications or recurrence. Resection of an accessory parotid mass can be performed via an endoscope-assisted transoral approach. In this study, we describe the procedure of the endoscope-assisted transoral resection.
