Group 1: A pure tone audiogram is performed before and after the operation.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Developing a method for decision making on two different coupling systems for the FMT actuator of the VSB (e.g. incus vs. stapes) or retrograde activation (round window). This should be based on electrophisiological measurements. | — |
Secondary
| Measure | Time frame |
|---|---|
| Comparison between the measurment of the best coupling system before and after wound closure at the end of the operation. What role plays the reconstruction of the middle ear layers and the ear packing on the performance of the VSB? Comparison with the vibrogramm 24 h postoperative and 3 months after surgery. What are the short and long term healing effects and on the acoustic performance of the VSB? | — |
