Single-channel versus bilateral multichannel cochlear implant results : a case report

Pre- and postoperative audiologic findings are compared in a patient who underwent three cochlear implant surgeries: an initial single-channel device in a recently deafened ear with no residual hearing, followed by a multichannel device in a congenitally deafened ear with a severe to profound loss, and subsequent explantation of the single-channel device and reimplantation with a multichannel device.
