The Effect of Endoscopy-assisted Transoral Parotid Gland Tumor Excision Compared With Traditional Operation

Endoscopic-assisted surgery has become a popular technique in salivary gland surgery, particularly for parotid gland tumors. However, this technique has not yet been routinely applied to transoral parotid tumor resection. This retrospective study aimed to evaluate the outcomes of gland-preserving surgery in patients with benign parotid tumors undergoing endoscopic-assisted transoral resection. The study included 30 patients with benign parotid tumors who underwent gland-preserving tumor resection: 15 underwent endoscopic-assisted transoral resection, while the other 15 underwent conventional tumor resection via the Blair S-shaped incision. Surgical feasibility, perioperative variables, postoperative appearance, and functional outcomes were assessed. In both groups, all tumors were completely removed with negative margins. No significant differences were observed between the two groups in terms of intraoperative blood loss, postoperative drainage volume, average incision length, or facial nerve injury. However, the endoscopic-assisted transoral group demonstrated superior cosmetic outcomes. No tumor recurrence was observed during the 1-6 month follow-up period. Therefore, endoscopic-assisted transoral parotid tumor resection is a safe approach for benign parotid tumors, offering both favorable functional and aesthetic results.
