Summary
Using a standard 4.5 mm prosthesis for stapes surgery is safe and effective. This approach significantly improves hearing outcomes in otosclerosis patients, reducing surgical time and complexity.
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Devices
Background:
- Stapes surgery outcomes are influenced by prosthesis length, with debate on standard vs. custom sizes.
- Otosclerosis treatment often involves stapedotomy, a procedure requiring precise prosthesis fitting.
Purpose of the Study:
- To evaluate the efficacy and safety of using a standard 4.5 mm stapes prosthesis without intraoperative measurements.
- To assess surgical outcomes in primary stapedotomy for otosclerosis.
Main Methods:
- Retrospective analysis of 99 patients with otosclerosis undergoing primary stapedotomy.
- Utilized a standardized 4.5 mm fixed-length prosthesis between January 2017 and February 2023.
- Compared pre- and post-operative air-bone gap (ABG) and noted complications.
Main Results:
- Significant improvement in mean ABG from 27.9 dB to 3.95 dB (p < 0.05).
- 96.96% of patients achieved a post-operative ABG of ≤10 dB.
- Low complication rate, including transient dizziness in three patients and one case of granuloma.
Conclusions:
- A standardized 4.5 mm prosthesis is a safe and effective option for stapedotomy in otosclerosis.
- This method simplifies surgery, reduces operative time, and avoids measurement complexities.
- The study supports the use of standard-size prostheses for successful stapes surgery outcomes.
