[Extruded cochlear implant magnet covered with a temporoparietal fascial flap. A case report].

Complications are infrequent after cochlear implant surgery but they might occur despite careful preoperative planning and meticulous surgical technique. Among the most commonly encountered problems are those associated with the postauricular flap. An exposed, and therefore contaminated, device requires immediate attention and intervention. Cochlear implantation revision surgery is justified by two main reasons, the high price of these devices and the difficulty of reimplantation, due to cochlear fibrosis and ossification after its removal. There are multiple options in cochlear implantation revision surgery with infected device. However, the temporoparietal fascia flap is highly vascularized and provides some advantages over other alternatives. We report a case of a 5 year old boy with bilateral sensor neural hearing loss, who suffered a device extrusion three years after its implantation.
