Design outcomes

Primary

MeasureTime 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

MeasureTime 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).
