Summary

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.

Conditions

  • Benign Tumor of Parotid Gland
  • Endoscope-assisted Surgery
  • Gland Preservation
  • Minimally Invasive Surgery

Interventions

PROCEDURE

Endoscopic-assisted transoral approach for parotid tumor resection

The buccal mucosa was incised in front of the mandibular ligament of the inner wing of the mouth, the submucosal tissue was separated, and important structures such as the buccal nerve, parotid duct, and facial nerve were protected. The tumor was completely resected while preserving the parotid gland.

PROCEDURE

Blair S-shaped incision for parotid tumor

The Blair S-shaped incision was made through an anterior auricular incision. After cutting the skin, the flap was reflapped. The greater auricular nerve and facial nerve were separated and protected, and the tumor was completely resected.
