Endoscopy-assisted transoral resection of large benign parapharyngeal space tumors.

We have evaluated the outcomes of endoscopically-assisted resection of large benign tumours of the parapharyngeal space by an intraoral approach. Six patients with primary benign tumours were treated in this way. The lesions were pleomorphic adenomas, Warthin's tumour, and schwannoma. The sizes of the tumours varied from 4×4 cm to 7×7 cm. All tumours were removed completely without rupture and without damage to the facial nerve. No patient developed any permanent postoperative complications such as damage to the facial nerve, salivary fistula, or limited mouth opening. The cosmetic effects were excellent. The patients were followed up for 8 to 21 months without recurrence. Endoscopically-assisted transoral resection of large benign tumours of the parapharyngeal space is a simple and safe technique that achieves excellent aesthetic and functional results.
