Summary
Revision stapes surgery can be effective after initial surgery failure, but audiological outcomes are generally less successful than primary procedures. Setting realistic expectations and distinct evaluation standards is crucial for this complex otologic surgery.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Background:
- Revision stapes surgery is a complex otologic procedure with limited data on expected outcomes.
- Established audiological standards for successful revision stapes surgery are lacking.
- This study aims to define realistic expectations for hearing results and complications.
Purpose of the Study:
- To determine expected audiological results after revision stapes surgery.
- To identify potential complications associated with revision stapes surgery.
- To establish realistic thresholds for surgical success in revision stapes procedures.
Main Methods:
- A systematic review was conducted following PRISMA guidelines across multiple databases.
- Twelve articles comprising 1032 cases of revision stapes surgery were analyzed.
- Publication quality was assessed using a modified Newcastle-Ottawa Scale.
Main Results:
- Average air-bone gap gain was 17.3 dB, and average air conduction gain was 17.5 dB.
- Postoperative air-bone gap averaged 11.1 dB, with 53.3% of cases achieving 0-10 dB.
- Sensorineural hearing loss (SNHL) occurred in 1.6% of cases, with no reported equilibrium disorders.
Conclusions:
- Revision stapes surgery offers an effective solution for cases where primary stapes surgery has failed.
- Audiological results from revision stapes surgery are generally inferior to primary stapedotomies.
- Different expectations and evaluation standards are necessary for revision stapes surgery compared to primary procedures.
