Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Reduction of the surgical trauma in various phases of surgery (drilling, opening of the round window, during and after electrode insertion) with the aim of hearing preservation | — |
Secondary
| Measure | Time frame |
|---|---|
| Correlation between intraoperative CM results, postoperative CM results and hearing preservation Specificity of CM results regarding electrode carrier during and after insertion Mapping of the functional OHCs in CI patients, intra- and postoperatively Development of a statistical cochlear model, for an estimation of the CI rehabilitation results Correlation of ECochG results with QoL scores and postoperative acoustic results with the CI in two patient groups: with and without residual hearing Effect of an acoustic feedback signal to the surgeon for the temporal reference during electrode insertion | — |
