Outcomes

Primary Outcomes

Concomitant Medication Used

Time Frame: 6 months post-surgery to 24 months post-surgery

Concomitant medication are collected from the participant's last visit in study CBAS5751 (6 months post-surgery)

Number and Type of Reported Device Deficiencies

Time Frame: 6 months post-surgery to 24 months post-surgery

The device deficiencies are collected from the participant's last visit in study CBAS5751 (6 months post-surgery) and categorized by relationship

Change in Audiometric Thresholds With the Active Osseointegrated Steady-State Implant System at 12 Months Post-surgery and 24 Months Post-surgery Compared to Preoperative Thresholds Via an Audiogram

Time Frame: Baseline before surgery, 12 months and 24 months post-surgery

Bone- and air conduction thresholds, masked and unmasked

Number and Type of Reported Adverse Events

Time Frame: 6 months post-surgery to 24 months post-surgery

The adverse events are collected from the participant's last visit in study CBAS5751 (6 months post-surgery) and categorized by system organ class system

Socio-economic Health Care Data Via the Client Service Receipt Inventory (CSRI) Survey

Time Frame: 24 months post-surgery

Demographic data (marital status, cohabitation, usual place of residence, education level), employment status, Healthcare utilization and Hearing rehabilitation data are collected
