Long term hearing outcome of stapedotomy

Lana Dabbagh*, Abdulkhaliq Emin

Background: Otosclerosis is a bone disorder affecting the temporal bone, resulting in stapes fixation. leading to gradual and progressive conductiveand mixed hearing loss. Stapedotomy is a reliable and safe procedure with positive hearing outcomes. Objective: This study aims to evaluate the long-term hearing results following stapedotomy. Patients and Methods: A retrospective study on long term outcomes following stapedotomy in Erbil/Iraq. The study focused on patients who underwent surgery between June 2010 and June 2014, with a minimum follow-up period of 10 years. During this time, 65 patients (40 females and 25 males), received treatment. The outcomes of pure-tone audiometry were evaluated preoperatively, one month postoperatively, and at later stages to assess the long-term impact of time on stapedotomy surgery. Results: The mean air conduction preoperatively was 51.1dB, mean bone conduction was 21.3dB, and mean air bone gap was 29.2. The mean bone conduction readings were 21.33 preoperative, 16.23 early postoperative and 22.33 late postoperative. While the mean air bone gap results were 29.23 preoperative, 8.46 in early postoperative and 14.88 in late postoperative. Comparison between means of preoperative, early postoperative, and late postoperative shows statistically significant differences. Specially comparisons of early and late postoperative results are statistically significant. Conclusions: Although patients generally report satisfactory hearing but long term follow up for stapedotomy shows that the time has a negative impact on the results in form of air conduction and bone conduction
