Background: Hearing preservation during cochlear implantation has become progressively more important. Specifically, non-traumatic electrode insertions might help to facilitate preservation and subsequent electric acoustic stimulation (EAS or Hybrid stimulation). However, the mechanisms of hearing loss during cochlear implantation remain unknown. In an effort to improve our understanding and the outcomes of hearing preservation during cochlear implantation, we have developed an animal model. This model allows us to record early auditory parameters during electrode insertions and thus correlate electrophysiological and mechanical findings. Previously, we demonstrated our ability to detect cochlear trauma using a rigid electrode. However, human surgery features flexible electrodes and in an effort to simulate this, we have developed a flexible array suitable for implantation in the gerbil.
