| description | 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 dB (range 9–20 dB) postoperatively (p = 0.00). At 6 months follow-up, <20 dB ABG was achieved in 93.33% of the patients. No major intraoperative/postoperative complications were detected. Conclusion: A 3 mm rigid nasal endoscope can be effectively used in stapedotomy to obtain adequate audiological outcomes. It can be considered as a better alternative to the standard microscope or 4 mm endoscope in preserving the posterior canal wall and chorda tympani nerve while minimizing operative time without causing significant complications. |
