Magnet Choice of the Osia 2 Sound Processor at 12 and 24 Months Post-surgery Compared to Last Performed Measurement (3 or 6 Months) in the CBAS5751 Study 3 or 6 months post-surgery, 12 and 24 months post-surgery Magnet strength ranging from 1 to 4, strength 1 being the weakest and 4 the strongest. If the magnet strength has been changed the reason for change is captured in free text
Change in Hearing Performance With the Active Osseointegrated Steady-State Implant System at 12 Months and 24 Months Post-surgery Compared to Last Performed Measurement (3 or 6 Months) in the CBAS5751 Study Assessed Via Audiometric Thresholds 3 or 6 months post-surgery, 12 and 24 months post-surgery Sound-field (Pure Tone Average 4, mean of 0.5, 1, 2 and 4 kHz)
Change in Health-related Quality of Life With the Active Osseointegrated Steady-State Implant System at 12 and 24 Months Post-surgery Compared to Last Performed Measurement (3 or 6 Months) in the CBAS5751 Study 3 or 6 months post-surgery, 12 and 24 months post-surgery Assessed via the Health Utilities Index (HUI) questionnaire. Change of health status and health related quality of life using the generic quality of life scale Health Utilities Index when wearing the Active Osseointegrated Steady-State Implant System. A health utility value of 1.00 indicates perfect health while a score of 0.00 indicates death. The change in scores will be presented. A positive value indicates an improved quality of life, a negative value indicates impaired quality of life.
Change in Self-reported Hearing Outcome With the Active Osseointegrated Steady-State Implant System at 12 and 24 Months Post-surgery Compared to Last Performed Measurement (3 or 6 Months) in the CBAS5751 Study 3 or 6 months post-surgery, 12 and 24 months post-surgery Assessed via the Speech, Spatial and Qualities of Hearing Scale (SSQ) questionnaire. Measuring change of speech, spatial and hearing experiences with the Active Osseointegrated Steady-State Implant System. The Total score summarizes the parameters speech, spatial and hearing. A scale from 0 to 10 is used, where 0 represents "can not hear at all", and 10 "hear perfectly". An increase of an SSQ value reflects an improvement. The change in scores will be presented. A positive value indicates improved hearing, a negative value indicates impaired hearing.

APHAB produces a global score and scores for four subscales: Ease of Communication, Reverberation, Background Noise, and Aversiveness. Global score is the average of all subscales. All scales range from 0-100%, where 0% indicates no problem and 100% indicates always problem. A decrease in the APHAB values indicates an improvement. The difference in scores will be presented. A positive value indicates an improvement, a negative value an impairment.
