Summary
Stapedectomy surgery improved hearing in 66.7% of patients with far-advanced otosclerosis. The Rinne test effectively distinguished otosclerosis from sensorineural hearing loss, confirming stapedectomy benefits for profound hearing loss.
Area of Science:
- Otolaryngology
- Audiology
- Neurosurgery
Background:
- Otosclerosis is a condition causing progressive hearing loss.
- Far-advanced otosclerosis presents significant audiological challenges.
- Stapedectomy is a surgical option for hearing restoration.
Purpose of the Study:
- To describe far-advanced otosclerosis.
- To evaluate stapedectomy outcomes in patients with far-advanced otosclerosis.
- To identify diagnostic indicators for otosclerosis.
Main Methods:
- Retrospective case review of 78 ears from 60 patients.
- Stapedectomy performed on all ears with far-advanced otosclerosis.
- Hearing outcomes assessed via air conduction (AC), bone conduction (BC), speech discrimination, and Rinne test.
Main Results:
- Overall hearing improvement in 66.7% of operated ears.
- Higher improvement rates observed in ears with measurable AC and BC.
- The Rinne test with a 256-Hz tuning fork showed diagnostic value.
Conclusions:
- Stapedectomy offers significant benefit for profound hearing loss in far-advanced otosclerosis.
- The Rinne test is crucial for differentiating otosclerosis from other hearing loss types.
- Surgical intervention is particularly beneficial when some measurable hearing exists.
