Summary
Revision stapedectomy rarely causes contralateral sensorineural hearing loss. This rare complication, possibly due to sympathetic cochleolabyrinthitis, requires careful consideration in otologic surgery.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Background:
- Stapedectomy is a common surgical procedure for otosclerosis.
- Potential complications include sensorineural hearing loss.
Purpose of the Study:
- To investigate if revision stapedectomy can cause hearing loss in the opposite ear.
- To identify risk factors for contralateral hearing loss after stapedectomy.
Main Methods:
- Retrospective review of 148 patients who had primary or revision stapedectomy.
- Analysis of audiological data, including air and bone conduction thresholds and speech reception thresholds.
Main Results:
- Stapedectomy improved hearing in the operated ear.
- No significant changes in hearing were observed in the contralateral ear for most patients.
- Two patients experienced significant hearing decline in the contralateral ear, both after revision surgery.
Conclusions:
- Revision stapedectomy is rarely associated with contralateral hearing loss.
- Sympathetic cochleolabyrinthitis is a potential cause of this rare complication.
