Summary
Stapedectomy effectively corrects small air-bone gaps in otosclerosis patients. This surgery significantly improves pure-tone average (PTA) hearing, even for mild hearing loss.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Background:
- Stapedectomy is a surgical procedure to restore hearing in patients with otosclerosis.
- Debate exists regarding the efficacy of stapedectomy for small air-bone gaps (≤10 dB).
Purpose of the Study:
- To evaluate the outcomes of stapedectomy in patients with small air-bone gaps.
Main Methods:
- A retrospective analysis of 154 patients with suspected otosclerosis undergoing exploration.
- Stapedectomy was performed on 136 patients (88.3%).
- Postoperative hearing outcomes, including pure-tone average (PTA), were assessed.
Main Results:
- The mean PTA improved by 16.7 dB after stapedectomy.
- Bone conduction PTA was overdosed by 8.1 dB.
- 89.7% of patients achieved a PTA closure of ≥0 dB.
Conclusions:
- Stapedectomy is an effective surgical option for addressing small air-bone gaps caused by otosclerosis.
- The procedure successfully eliminates or overdoses even minor air-bone gaps, improving hearing.
