Brief Summary
The goal of this clinical trial is to assess the safety of intracochlear application of VSF1.01 for the reduction of cochlear implant surgery related trauma in patients with profound hearing loss with or without non-functional residual hearing in low frequencies and cochlear implantation. The main questions it aims to answer are: Primary objective: Safety of intracochlear application of VSF1.01 in patients receiving cochlear implantation Secondary objectives: Effectiveness on
- 1.neural responses of auditory nerve
- 2.speech understanding
- 3.hearing thresholds
- 4.electrode impedances
