Long-term effect of otosclerosis on bone conduction
The Laryngoscope
|July 1, 1979
Summary
Otosclerosis can cause more sensorineural hearing loss than typically seen in the general population. Some individuals with otosclerosis may experience a worsening of this hearing loss over time.
Area of Science:
- Otolaryngology
- Audiology
- Neurosurgery
Background:
- Long-term studies on sensorineural function in otosclerosis are limited.
- Previous reports on lateral canal fenestration suggest stable bone conduction.
- Clinical experience indicates potential progression of sensorineural hearing loss in some otosclerosis patients.
Purpose of the Study:
- To investigate the long-term sensorineural function in patients with clinically proven otosclerosis.
- To compare sensorineural hearing loss in otosclerosis patients to the general population.
Main Methods:
- Review of audiological data from over 500 ears in patients diagnosed with otosclerosis.
- Analysis of long-term sensorineural hearing function trends.
Main Results:
- Patients with otosclerosis exhibit a higher degree of sensorineural hearing loss compared to the general population.
- A subset of otosclerotic ears demonstrates a tendency towards progressive sensorineural hearing loss.
Conclusions:
- Otosclerosis is associated with greater sensorineural hearing loss than typically observed.
- Progression of sensorineural hearing loss is a potential concern in some individuals with otosclerosis.
