Summary
A second stapedotomy surgery for otosclerosis can significantly improve hearing outcomes. This procedure increases the likelihood of achieving normal hearing in at least one ear and symmetrical hearing in most patients.
Area of Science:
- Otolaryngology
- Audiology
- Surgical Outcomes
Background:
- Otosclerosis is a common cause of conductive hearing loss.
- Stapedotomy is a surgical procedure to restore hearing in otosclerosis patients.
- Evaluating outcomes after bilateral stapedotomy requires functional assessment.
Purpose of the Study:
- To evaluate the audiological results of second-ear stapedotomy in patients with bilateral otosclerosis.
- To assess the functional hearing benefit after a contralateral stapes surgery.
- To determine the impact of bilateral stapedotomy on achieving symmetrical normal hearing.
Main Methods:
- Retrospective analysis of audiological data from 72 stapedotomies.
- Utilized the Glasgow benefit plot (GBP) for functional hearing evaluation.
- Data included pre- and postoperative hearing levels and surgical details.
Main Results:
- Second-ear stapedotomy enhances the probability of achieving at least one ear with normal hearing.
- The majority of patients experienced symmetrical normal hearing after bilateral stapedotomy.
- The Glasgow benefit plot proved effective for assessing functional hearing gains.
Conclusions:
- Contralateral stapedotomy is beneficial for patients with bilateral otosclerosis.
- Bilateral stapedotomy improves functional hearing and symmetry.
- The Glasgow benefit plot is a valuable tool for evaluating stapes surgery outcomes.
