Endoscopic-Assisted Resection of Benign Tumors of the Accessory Parotid Gland

Abstract

Modified endoscopically assisted resection of benign tumors in the accessory parotid gland region (APGR) has been reported, and the surgery confers a potential risk of injury to the great auricular nerve. This clinical research study provides an updated approach for the resection of benign tumors of the APGR. Thirteen cases diagnosed with primary benign tumors in the APGR were treated by endoscopically assisted resection through a margin of the tragus, and its feasibility was evaluated. All tumors were completely resected. The procedures lasted 45 to 70 minutes (mean, 54 minutes). None of the endoscopically assisted surgeries proceeded to open surgery. The patients were followed for 3 to 14 months, without postoperative complications, including pain, facial or auricular nerve weakness, salivary fistula, infection, tumor recurrence, Frey syndrome, or depression deformity. The scars were concealed and esthetically satisfactory. Endoscopically assisted resection of benign tumors through a margin of the tragus in the APGR is a safe technique that achieves excellent esthetic and functional results.
