      Abstract

      Endoscope-assisted surgery is becoming a preferred technique in salivary gland surgery. However, this technique has not yet been applied in submandibular gland (SMG) preservation surgery. This retrospective study was performed to evaluate the outcomes of endoscope-assisted gland-preserving surgery through a hairline incision in patients with benign SMG tumours. The study included 38 patients with benign SMG tumours who underwent tumour excision with gland preservation: 19 who underwent local excision of the tumour through an endoscope-assisted hairline approach and 19 who received the conventional cervical approach. The feasibility of the surgical procedure, perioperative patient variables, and postoperative appearance and functional outcomes were evaluated. Patients in both groups had their tumours removed successfully with tumour-free margins. The intraoperative blood loss, postoperative amount of drainage, mean length of the incision, and unstimulated saliva flow rate did not differ between the two groups. There was no difference in the stimulated saliva flow rate between the preserved gland and unaffected SMG. The aesthetic result was better in the endoscope-assisted hairline incision group. No tumour recurrence occurred during follow-up (range 12–52 months). Thus, gland-preserving tumour dissection appears to be a safe method for benign SMG tumours, with good functional results. Furthermore, the endoscope-assisted hairline incision is a feasible method with excellent cosmetic results.
