Objective: Transoral surgery is gaining favor because it has the advantage of leaving no scar after surgery. The aim of this study was to evaluate the technical feasibility and safety of endoscope-assisted transoral accessory parotid mass excision.Study Design: Multicenter, prospective, observational study.Methods: This study was designed as a 7-year, prospective, multicenter evaluation of endoscope-assisted transoral accessory parotid mass excision. Clinical outcomes and complications related to the procedures were evaluated in patients.Results: Twenty patients underwent endoscope-assisted transoral accessory parotid mass excisions, and 22 patients underwent conventional parotidectomy approach excisions. There was no significant difference with respect to overall demographic characteristics between the groups. However, the operation times were shorter in the transoral approach group (P = 0.001), and cosmetic satisfaction was much better in the transoral group (P < 0.001).Conclusion: Endoscope-assisted transoral accessory parotid mass excision is a potentially safe and effective procedure with excellent outcomes.

Transoral dermoid cyst excision is a potentially safe and effective method that can lead to easy and quick removal of an oral cavity dermoid cyst, with excellent cosmetic outcomes.
