Summary
Revision stapes surgery outcomes were reviewed, with prosthesis displacement being a common failure cause. Preventing primary surgery issues and reducing trauma offer the best hearing results.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Background:
- Revision stapes surgery addresses hearing loss after initial stapedotomy.
- Understanding failure causes is crucial for improving surgical outcomes.
Purpose of the Study:
- To analyze the results of 63 revision stapes surgeries conducted between 1978 and 1994.
- Identify common causes of failure and factors influencing hearing outcomes.
Main Methods:
- Retrospective review of 63 revision stapes surgery cases.
- Analysis of operative findings, causes of failure, and audiological results.
Main Results:
- Prosthesis displacement was the most frequent cause of failure.
- 58.7% of patients achieved a postoperative hearing improvement within a 20-dB air-bone gap.
- Hearing gain correlated with operative findings, with prosthesis issues yielding better results.
- Only 40% of cases demonstrated symmetric normal hearing based on Glasgow benefit plot evaluation.
Conclusions:
- Preventing primary stapes surgery failures is key to favorable revision outcomes.
- Minimizing surgical trauma during primary procedures may improve long-term hearing results.
