Summary
Revision stapedectomy in Israel achieved significant hearing improvement in 67.6% of patients, with common findings including prosthesis malfunction. Despite lower success than primary surgery, these revision outcomes support their clinical value.
Area of Science:
- Otolaryngology
- Audiology
- Surgical Innovation
Background:
- Otosclerosis management often involves stapedectomy.
- Revision stapedectomy is performed when primary surgery fails or complications arise.
Purpose of the Study:
- To assess audiometric outcomes and surgical findings of revision stapedectomy.
- To evaluate the efficacy of revision stapedectomy in a tertiary referral center.
Main Methods:
- Retrospective study of 78 patients undergoing revision stapedectomy over 13 years.
- Audiometric evaluation and analysis of intraoperative findings.
- Mean follow-up of 1.5 years.
Main Results:
- 67.6% of patients achieved closure of the air-bone gap to within 10 dB.
- Average pure tone average (PTA) hearing improvement was 22.5 dB.
- Common operative findings included prosthesis malfunction (42.6%) and incus necrosis (22%).
Conclusions:
- Revision stapedectomy yields results comparable to other large studies.
- Hearing gains are influenced by surgical findings, prior revision history, and ossicular chain integrity.
- The study justifies the role of revision stapedectomy in managing hearing loss.
