The insertion of an intracochlear electrode array may cause trauma to cochlear structures which can result in degeneration of neural elements, jeopardizing the potential benefits of electrical stimulation. Safety studies for the assessment of trauma associated with the Nucleus 22 standard electrode array involved animal experiments as well as insertion studies in post mortem temporal bones. However, there are only few histological studies of temporal bones from deceased cochlear implant patients. A review of our temporal bone collection of implantees originating from a variety of centres has been conducted to evaluate the effects of electrode insertion trauma associated with the Nucleus 22 standard array.
