Summary
The RetroX auditory implant significantly improves hearing for adults with high-frequency hearing loss, with all patients reporting high satisfaction. This semi-implantable device offers a new therapeutic option without external auditory canal occlusion.
Area of Science:
- Otolaryngology
- Biomedical Engineering
- Audiology
Background:
- High-frequency sensorineural hearing loss (ski-slope audiogram) affects numerous adults.
- Current management options may involve occlusion of the external auditory canal.
- There is a need for effective hearing solutions that do not obstruct the ear canal.
Purpose of the Study:
- To evaluate subjective satisfaction with the RetroX auditory implant.
- To objectively measure hearing gain provided by the RetroX.
- To assess the efficacy of the RetroX in patients with high-frequency hearing loss.
Main Methods:
- Retrospective case review of 10 adult patients with high-frequency hearing loss.
- Utilized the RetroX, a semi-implantable auditory implant with a titanium tube.
- Assessed outcomes using satisfaction questionnaires, pure-tone and speech audiometry (in quiet and noise), and azimuth audiometry.
Main Results:
- All 10 patients reported high subjective satisfaction with the RetroX implant.
- Statistically significant improvements in pure-tone thresholds at 1, 2, and 4 kHz were observed.
- Speech reception threshold improved by 9 dB in quiet, and speech intelligibility improved significantly in noise across various signal-to-noise ratios.
Conclusions:
- The RetroX auditory implant is a viable semi-implantable hearing aid.
- It effectively improves hearing in patients with high-frequency hearing loss without occluding the ear canal.
- RetroX presents a novel therapeutic alternative for managing this specific type of hearing impairment.
