Primary endoscopic stapedotomy using 3 mm nasal endoscope: Audiologic and clinical outcomes.

ABSTRACT:

Objective

To report the use of a 3 mm rigid nasal endoscope in primary endoscopic stapedotomy and clinical and audiological outcomes.

Materials and methods

Thirty patients diagnosed with primary otosclerosis underwent endoscopic stapedotomy that was performed using a 3 mm nasal endoscope (Karl Storz). At 6 months follow-up, the patients were evaluated for intraoperative findings, postoperative hearing outcomes and complications.

Results

Canaloplasty was performed in 2 (6.66%) patients, and no curettage of the canal wall was required in 12 (40%) patients. Transposition of the chorda tympani nerve was conducted in 11 (36.66%) patients. The average duration of surgery was 36 min (range 31-65 min). The air-bone gap (ABG) was 35 dB (range 24-50 dB) preoperatively and 14.63
