Endoscopic stapedotomy: A comparison between the conventional approach versus CO₂ laser‐assisted surgery

Background Although the utility of laser fiber in microscopic stapes surgery has been documented past, their role can be highly emphasized endoscopic surgery, especially difficult anatomical situations. Methods This is a retrospective analysis cases where total 46 patients (22 conventional stapedotomy and 24 CO2 laser-assisted stapedotomy) were included study. The clinical parameters assessed both preoperative postoperative periods respective groups later compared 12 weeks after stapedotomy. Results A 90.90% (20/22) 95.83% (23/24) had <20 dB AB gap period (P = 0.71). Canaloplasty was required six none group needed same 0.01). Chorda tympani nerve manipulated 59.09% (13/22) 25.00% (6/24) group, respectively Conclusion audiological outcomes with fiber-enabled are comparable to it better tool narrow auditory canal, requiring minimal manipulation chorda nerve.
