Objective: The most widely accepted treatment for otosclerosis is currently microscopic stapes surgery under either local or general anesthesia. The aim of the study is to describe the surgical steps in endoscopic stapes surgery and to evaluate the audiologic and surgical outcomes. Materials and methods: All patients who underwent exclusive endoscopic stapes surgery or revision surgery for previous stapedotomy between November 2014 and September 2018 were enrolled in this study. Demographic data, surgical information, preoperative and postoperative pure tone averages and air bone gaps, intraoperative and postoperative complications and follow-up data were summarized and gathered in a database for further consideration and analysis. Results: In the period examined, 181 stapes surgical procedures were performed and out of these 150 met the inclusion criteria. There were no cases of major intraoperative complications. Sensorineural hearing loss was observed in one case. In one patient a gusher effect occurred during surgery. The postoperative air-bone gap improved significantly compared to the preoperative gap (8 vs 29 dB HL, respectively), and the mean air-bone gap closure was 20 dB HL. In 78.7% of cases, the observed postoperative air-bone gap was less than 10 dB HL and in 14% it was between 11 dB HL and 20 dB HL. An ABG closure lower than 20 dB HL was achieved in a total of 92.7% of patients. Conclusions: Endoscopic stapes surgery is a safe procedure with a low risk of peri- or postoperative complications and is a possible alternative to the traditional microscopic surgical procedure in the treatment of otosclerosis.
