Summary
Stapes surgery significantly improves hearing and quality of life for otosclerosis patients with mixed hearing loss. Many patients experience reduced hearing aid dependency after the procedure.
Area of Science:
- Otolaryngology
- Neurosurgery
Background:
- Otosclerosis is a condition causing conductive, mixed, or sensorineural hearing loss.
- Stapes surgery is a common treatment for hearing loss due to otosclerosis.
Purpose of the Study:
- To evaluate the effectiveness of stapes surgery in patients with otosclerosis and mixed hearing loss.
- To assess the impact of surgery on air conduction (AC) thresholds, air-bone gap (ABG), bone conduction (BC) thresholds, and quality of life.
Main Methods:
- Retrospective analysis of 121 patients with otosclerosis and mixed hearing loss.
- Preoperative and postoperative audiometric measurements (AC, BC, ABG).
- Glasgow Benefit Inventory (GBI) questionnaire for quality of life assessment.
Main Results:
- Average AC improved from 61.5 dB to 34.3 dB; average ABG closed from 27.1 dB to 6.1 dB.
- Bone conduction improved from 34.3 dB to 28.2 dB; 38% achieved AC <30 dB.
- 88% of respondents reported significantly increased quality of life (average GBI score of 56) and reduced hearing aid use by 5.48 hours/day.
Conclusions:
- Stapes surgery offers significant audiological and quality of life benefits for otosclerosis patients with mixed hearing loss.
- Preoperative bone conduction thresholds may not accurately predict surgical outcomes.
- Surgeons should consider cochlear reserve when assessing suitability for stapes surgery.
