Summary
The Vibrant Soundbridge, a semi-implantable hearing device, showed minimal long-term changes in hearing thresholds for sensorineural hearing loss patients. These changes were not significantly different from the non-operated ear.
Area of Science:
- Otolaryngology
- Biomedical Engineering
- Audiology
Background:
- Sensorineural hearing loss impacts adults, necessitating advanced rehabilitation devices.
- The Vibrant Soundbridge is a semi-implantable middle ear hearing device for hearing loss rehabilitation.
- Evaluating long-term effects of implanted hearing devices is crucial for patient outcomes.
Purpose of the Study:
- To assess the long-term audiological effects of the implanted component of the Vibrant Soundbridge.
- To analyze hearing threshold changes in patients with sensorineural hearing loss after implantation.
Main Methods:
- Retrospective analysis of audiological data from 39 patients implanted with the Vibrant Soundbridge.
- Data collected from multiple implant sites across France.
- Follow-up duration averaged 16 months, with 25 patients followed for over a year.
Main Results:
- Surgery for Vibrant Soundbridge implantation was uneventful in all cases.
- A statistically significant modification in hearing thresholds was observed at 0.5 kHz and 4 kHz.
- The observed threshold shifts (2.79 dB and 3.34 dB) were limited and not statistically different from the non-operated ear's progression.
Conclusions:
- The Vibrant Soundbridge demonstrates safe implantation with minimal long-term impact on hearing thresholds.
- Long-term audiological outcomes suggest the device's stability and limited effect on hearing thresholds.
- Further research may explore device efficacy in diverse patient populations.
