The piezoelectric OSIA is a well-established active transcutaneous bone anchored hearing system. The study retrospectively evaluates hearing results and subjective benefits in patients provided with the OSIA system at our clinic, and separately also looks at patients with moderate to severe mixed hearing loss.
Retrospective single-center data suggest OSIA may benefit suitable candidates, but the study's design (no control group, single site) limits confidence; do not change patient selection criteria based on this alone.
Real-world audiometric and patient-reported outcome data for active transcutaneous bone-anchored systems like OSIA remain limited, making even retrospective single-center reports relevant for clinical context.
- 01Retrospective monocentric study evaluated audiometric outcomes in OSIA piezoelectric bone-anchored hearing system users.
- 02Quality-of-life benefits were assessed using subjective patient-reported measures.
- 03Single-center, retrospective design limits generalizability and introduces selection bias.
- 04OSIA is an active transcutaneous system, meaning the processor sends vibrations through the skull without a skin-penetrating abutment.
- 05Results are directionally positive but should be interpreted with caution.
OSIA users show improved audiometric outcomes compared to unaided baselines.
