Summary
The Osia transcutaneous hearing device significantly improves hearing by 35.0 dB SPL across various hearing loss types. This bone-anchored hearing system shows a favorable safety profile, comparable to other implants.
Area of Science:
- Audiology and Otolaryngology
- Biomedical Engineering
- Hearing Science
Background:
- Conductive, mixed, and sensorineural hearing loss impact millions globally.
- Bone-anchored hearing solutions offer an alternative for individuals with specific hearing impairments.
- Transcutaneous bone conduction devices aim to improve audiological outcomes and patient quality of life.
Approach:
- A systematic review and meta-analysis was conducted.
- Searched Medline, Embase, SCOPUS, Cochrane CENTRAL, PROSPERO, and Cochrane Library.
- Included 14 studies (314 patients) analyzing the Osia device's functional gain and complication rates.
Key Points:
- The Osia device provided a pooled overall functional gain of 35.0 dB SPL.
- Significant gain was observed in conductive/mixed hearing loss (37.7 dB SPL).
- Complication rates, including explantation and infection, were low and comparable to similar devices.
Conclusions:
- The Osia transcutaneous hearing device demonstrates substantial audiological benefits.
- The device exhibits a good safety profile for patients with hearing loss.
- Future research should focus on frequency-specific gain, PROMs, and single-sided deafness benefits.
