title: Delayed extrusion of a cochlear implant: a case report of an implant extruding 21 months after the original operation.
abstract: We present a case report of a lady who received a Nucleus 22 Channel cochlear implant in July, 1992. She presented again in April, 1994 when the cochlear implant had extruded spontaneously. The possible aetiology of this extrusion, as well as the technique of surgical management, is discussed.
