Abstract

Objective: To evaluate the clinical and audiological outcomes of transcanal endoscopic resection of middle ear paragangliomas.

Study design: Retrospective multicenter study.

Setting: Tertiary referral center and private otology clinic.

Patients: Patients who underwent transcanal endoscopic surgery between January 2015 and September 2020.

Interventions: Transcanal endocope-assisted resection of middle ear paragangliomas.

Main outcome measures: Demographic data.

Results: Twenty-three patients (2 men, 21 women) with a mean (standard deviation [SD]) age of 50.5 (11.8) years and stage 1 or 2 disease were included in the study. The mean follow-up time was 2.7 years (range, 1-5 yr). Preoperatively, the mean (SD) air-conduction threshold was 33.8 (17.9) dB, and the mean (SD) air-bone gap was 13.1 (13.9) dB. Postoperatively, the mean (SD) air-conduction threshold was 25.7 (10.2) dB, the mean (SD) air-bone gap was 6.3 (6.1) dB. The mean (SD) hospital stay was 27.7 (9.9) hours. No tumor regrowth was detected on magnetic resonance imaging during postoperative follow-up.

Conclusions: Endoscopic transcanal tumor resection is effective and feasible in the treatment of stage 1 and 2 tumors and is associated with short operative time, low risk of perioperative and postoperative complications, and rapid discharge.
