초록
With the increasing of cochlear implantation, necessity of magnetic resonance imaging (MRI) of cochlear implant (CI) recipients is also increasing. This patient was previously reported as a case of reversion of internal magnet of CI after undergoing MRI. At that time, the CI device functioned normally after the polarity reversion of external device. Eight years later from that event, the patient came for sudden functional loss of the CI. Then, we found the patient’s internal magnet of CI was spontaneously extruded through the skin. The function of CI was perfectly recovered after the surgery for insertion of internal magnet.
Abstract
With the increasing of cochlear implantation, necessity of magnetic resonance imaging (MRI) of cochlear implant (CI) recipients is also increasing. This patient was previously reported as a case of reversion of internal magnet of CI after undergoing MRI. At that time, the CI device functioned normally after the polarity reversion of external device. Eight years later from that event, the patient came for sudden functional loss of the CI. Then, we found the patient’s internal magnet of CI was spontaneously extruded through the skin. The function of CI was perfectly recovered after the surgery for insertion of internal magnet.
