      The clinical characteristics of otosclerosis and benefit from stapedotomy: our experience of 48 patients (58 ears)

      Abstract

      Background: Stapedotomy has been proved to be one of the most efficient procedure to treat otosclerosis, various factors contribute to the diversity of the outcomes and controversial results exist from previous studies. Objectives: We evaluated clinical characteristics and outcomes of stapedotomy, as well as possible predictive factors of a successful outcome. Materials and methods: This retrospective study evaluated 58 ears from 48 patients with demographic data, plus short-term follow-up of hearing outcomes of 28 ears, and evaluated variables using univariate general linear regression analyses. Results: The average operation age was 41.54 years. A total of 87.5% (42/48) patients presented with bilateral otosclerosis. 39.66% (23/58) ears had CT finding before the surgery. Patients with persistent tinnitus accounted for 53.45% (31/58) and the average preoperative ABG of the 58 ears was 32.22 dB. We achieved good postoperative air-bone gaps (ABGs) overall but poor ABG closure at 4 kHz. No predictive factors were identified in the 28 ears that were followed up. Conclusions and significance: Delayed surgery may be attributable to insufficient recognition of otosclerosis. The fenestration size could be the reason for poor ABG closure at high frequency. However, more cases and longer follow-ups are required to confirm our findings.
