Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary endpoint: Insertion depth (in mm) of cochlear implant electrodes, determined algorithmically based on standard telemetry measurements of electrode impedances. Intraoperative (Month 0): During implantation, routine measurements are performed, including impedance telemetry and the recording of auditory nerve responses. In addition, a non-invasive measurement of the sound pressure level in the external auditory canal is conducted. Initial activation (Month 1) and follow-up fitting (Month 3): The initial and follow-up fitting sessions are routinely scheduled after cochlear implantation and include impedance telemetry as well as the recording of auditory nerve responses. | — |
Secondary
| Measure | Time frame |
|---|---|
| Course of electrical impedance (in kO) and its subcomponents during and after cochlear implantation, determined using standard telemetry or extended telemetry (use of different pulse durations). | — |
