Sponsor's own description

This trial is a pilot study to assess the feasibility of using Electrocochleography recorded from a cochlear implant intra-operatively in real time to monitor the progress of its insertion. Correlation between: 1. Observed changes in this signal during surgery and residual hearing loss post-operatively and 2. Recordings of this signal post-operatively and actual pure tone audiometry results will also be assessed.
