Otopathology in a case of multichannel cochlear implantation

The histopathology of the temporal bones of a patient who died of unrelated causes 10 weeks following cochlear implantation using a Richards Ineraid® device is presented. Deafness was caused by a prolonged course of intravenous gentamycin therapy 5 years prior to implantation.
