Insights
This study assessed stapes mobilization outcomes in pediatric otosclerosis patients. Auditory Brainstem Response (ABR) testing confirmed hearing improvements following the surgical procedure.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Context:
- Otosclerosis is a common cause of conductive hearing loss, particularly in young patients.
- Stapes mobilization is a surgical technique aimed at restoring hearing in otosclerosis cases.
- Evaluating surgical outcomes using objective measures like Auditory Brainstem Response (ABR) is crucial.
Purpose:
- To evaluate the effectiveness of stapes mobilization under anesthesia in children with otosclerosis.
- To assess hearing improvement by monitoring changes in Auditory Brainstem Response (ABR) parameters during and after surgery.
Summary:
- Auditory Brainstem Response (ABR) was performed at multiple intraoperative stages: pre-operation, post-tympanotomy, post-stapedotomy, post-prosthesis insertion, and post-operation.
- A reduction in the latency of wave V and the intervals I-V and III-V of the ABR was observed.
- These ABR changes indicate a reliable improvement in hearing function immediately following stapes mobilization.
Impact:
- Provides objective evidence of hearing improvement after stapes mobilization in pediatric otosclerosis.
- Highlights the utility of intraoperative ABR monitoring for assessing surgical success in real-time.
- Contributes to understanding the neurophysiological basis of hearing recovery in otosclerosis surgery.
Abstract:
The Authors executed checking a result of stapes mobilization under anesthesia in children, sick otosclerosis. The Study ABR was conducted before operations, after opening the drum cavity, making the hole in plate of stapes, installing the prosthetic device and at the end of operation. The reduction level of latency V wave and interval III-V and I-V waves are a reliable acknowledgement of the improvement of the hearing at the end of operation.
