About this trial
The goal of this interventional study is to confirm the safety and performance of the latest generation Osia System and to examine its benefits compared to the Baha Connect System in adults with mixed or conductive hearing loss who have a pre-existing Baha implant and Abutment (BIA300) and are transitioning to the Osia System.
The main questions this study aims to answer are:
* Is the safety and performance of the Osia System confirmed by study findings? * What are the benefits of the Osia System compared to the Baha Connect System?
Participants will:
* Undergo speech performance testing in both quiet and noisy environments * Provide ratings for various questionnaires

Trial outcomes
Primary outcomes
Change (within-subject) in speech reception threshold in noise measured at 65 dB SPL (pre-operative unaided and post-operative aided with the Osia System)
Speech perception in noise will be assessed using the Bamford-Kowal-Bench-Speech in Noise (BKB-SIN) test, which assesses speech recognition in the presence of background noise. This test consists of lists of sentences, each containing 3-4 key words, presented at 65 dB SPL with increasingly progressive levels of background noise. One point is awarded for each correctly repeated word, and the results are used to calculate the signal-to-noise ratio (SNR) at which 50% of the key words (SNR-50) are correctly repeated.
Secondary outcomes
The incidence rates of Adverse Events (AEs) and Device Deficiencies (DD) (both systems)
The incidence rates of all reported AEs per device type and specific rates for DD will be assessed. A breakdown by category will be provided to indicate the proportion of patients experiencing each category (by severity, by relatedness to device or procedure, and by seriousness) of AE and DD.
The frequency and types of healthcare interventions related (both systems)
The frequency and types of healthcare interventions (e.g., follow-up visits, treatments, and hospitalisations) associated with the use of the device systems will be collected.
Change (within-subject) in word recognition score in quiet measured at 65 dB SPL (pre-operative unaided and post-operative aided with the Osia System)
Word recognition in quiet will be measured using the Arthur Boothroyd (AB) Speech Test, which assesses speech recognition in a quiet surrounding. The AB test involves monosyllables presented at 65 dB SPL, with scores recorded as the percentage of correctly repeated words at each presentation level.
Total score and attribute scores from the Health Utilities Index (HUI)-2/3 questionnaire (Osia System)
The HUI-2/3 perception-based questionnaire involves a comprehensive health status and health-related quality of life, using 15 questions comprised of 8 attributes: Vision, Hearing, Speech, Ambulation, Dexterity, Emotion, Cognition, and Pain. A score is given that reflects overall quality of life, where 1 means perfect health and 0 means a state equivalent to death.
