Purpose:
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.
Patients And Methods:
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.
Results:
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.
Conclusion:
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.
