Summary
Stapes surgery significantly improves hearing, especially at lower frequencies. While high-frequency hearing may slightly decline, it does not impact speech understanding, leading to patient satisfaction.
Area of Science:
- Otolaryngology
- Audiology
- Surgical Outcomes
Background:
- Stapes surgery is a common procedure for hearing loss.
- Understanding post-operative hearing changes is crucial for patient outcomes.
Purpose of the Study:
- To evaluate hearing outcomes after stapes surgery.
- To analyze changes in air and bone conduction (AC&BC) hearing.
- To assess outcomes in a frequency-specific manner.
Main Methods:
- Retrospective cohort study of 245 ears (231 patients) undergoing stapedotomy.
- Pre-operative and post-operative (1 month and 1 year) pure tone audiometry (PTA).
- Analysis of AC, BC, and air-bone gap (ABG) thresholds.
Main Results:
- Significant improvement in AC thresholds (mean gain 20.44 dB).
- Improved ABG at all frequencies post-surgery.
- Slight, non-significant worsening of BC thresholds at high frequencies (>2000 Hz) at 1-year follow-up.
Conclusions:
- Stapes surgery effectively improves hearing, particularly at lower frequencies.
- Potential for high-frequency sensorineural hearing loss (SNHL) exists but is not clinically significant for speech.
- Patients generally report satisfaction with hearing outcomes post-surgery.
