Dislocation of cochlear implant magnet during 1.5 Tesla magnetic resonance imaging despite head bandaging, and its repositioning using an endoscopic approach

Dislocation of the cochlear implant magnet is an uncommon but recognised complication of magnetic resonance imaging in a patient with a cochlear implant.Case reportThis paper reports a case of cochlear implant magnet dislocation despite head bandaging. The patient subsequently underwent endoscopic repositioning of the magnet under general anaesthesia. The cochlear implant system was tested intra-operatively and confirmed to be functioning. The patient was well at follow up and the small wound healed well with no complications. This report presents the endoscopic technique as a viable minimally invasive surgical approach to address cochlear implant magnet dislocation.
