Transcanal Endoscopic Management of Middle Ear Paragangliomas

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. Intervention(s) Transcanal endocope-assisted resection of middle ear paragangliomas. Main Outcome Measure(s) 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.
