Summary
Brief summary (as posted)
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.

- Endoscopic-assisted transoral approach for parotid tumor resection
- description
- A 5-7 cm curvilinear incision was made with electrocautery on the buccal mucosa along the anterior border of the pterygomandibular raphe on the affected side. The mucosal flap was elevated superiorly, with preservation of the parotid duct and buccal nerve. Two assistants were required to maintain retractor elevation, and hold the endoscope. Electrocautery dissection was performed in three dimensions to expose the anterior borders of both the medial pterygoid muscle and masseter muscle, along with the tumor mass. The surgeon manipulated either electrocautery or ultrasonic scalpel for precise dissection, and used forceps to retract or displace muscular and parotid tissues. Hemoclips were applied to achieve hemostasis. Blunt dissection through normal peri-tumoral tissue ensured complete tumor resection while preserving critical structures including facial nerve branches, buccal nerve, and parotid duct.

- Blair S-shaped incision for parotid tumor
- description
- The traditional parotid tumor resection surgery employs a Blair S-shaped incision, starting from the anterior edge of the tragus, extending along the auricle to the earlobe, then curving downward along the posterior border of the mandibular ramus to a point 2-3 cm below the mandibular angle. The skin and subcutaneous tissues are incised to the superficial layer of the parotid fascia, followed by anterior flap elevation while preserving the branches of the greater auricular nerve. The parotid gland and tumor are then exposed, with careful dissection of the facial nerve before removing the tumor and gland. The preservation of critical structures is similar to that in the endoscopic-assisted transoral approach group. A negative-pressure drainage tube is placed at the incision site, and the wound is closed in layers.
