There are evidences supporting stapes mobilization, but there are concerns regarding refixation and recurrence of conductive hearing loss; therefore, supporting stapedectomy. Methods: In this retrospective study, clinical records, operative notes, and audiologic data of patients with stapes fixation (1994–2011) were analyzed. Audiometric findings are reported according to the recommendations of the Committee on Hearing and Equilibrium 1995 Guidelines for the Evaluation of Results of Treatment of Conductive Hearing Loss. Results: In the present study, 66 patients were enrolled (23 male, 43 female). Stapedectomy and stapes mobilization both had good hearing results (12.1 dB vs. 10.6 dB reduction in ABG) and there was no significant difference. Overall, 63.6% of patients had achieved good results (mobilization: 57.9%, stapedectomy: 71.4%). The difference in success rate between the two groups was not statistically significant. Conclusions: Stapedectomy and mobilization of stapes both seem to be efficacious and safe in the treatment of stapes involvement in tympanosclerosis. The hearing improvement is long lasting in both procedures. https://ajs.tums.ac.ir/index.php/ajs/article/view/6 https://ajs.tums.ac.ir/index.php/ajs/article/download/6/6
