Abstract
OBJECTIVE: Osia is a new, transcutaneous, active bone-conduction implant. This study aimed to compare the BAHA Attract and the first-generation Osia system after BAHA Attract to Osia conversion surgery. METHOD: Five patients who had previously used the BAHA Attract system were converted to the first generation of the Osia system. Surgical aspects of the two different systems, audiological performance and subjective opinions of the patients were investigated. Pure tone audiometry and speech audiometry in quiet was performed with each patient's BAHA 5 sound processor on Attract, and the test battery was repeated six weeks after the Attract to Osia conversion and at different time points after the first fitting. Details of the surgery and patients' feedback were analysed. RESULTS: Audiology tests showed significant improvement when using either system; however, the Osia system performance was better. Based on patient feedback, all the five implantees preferred the Osia system. CONCLUSION: The study results suggest that the Osia system is a safe and powerful hearing implant that provides good clinical outcomes.
