N2  - OBJECTIVES: To date, over 200 000 cochlear implants (CIs) have been implanted worldwide and the incidence is still increasing. We present a case of traumatic displacement of CI magnet to raise awareness about this complication and to highlight the need for vigilance during surgery as well as for proper counseling. <br><br>METHODS: The clinical presentation of a 1.5-year-old boy with a traumatic displacement of a CI magnet was presented and the literature was reviewed for this rare complication. <br><br>RESULTS: After minor head injury, the sound processor could no longer connect to the CI. X-ray imaging demonstrated displacement of the CI magnet. During revision surgery, the magnet was replaced by a new magnet in the silicon holding cap. Intraoperative impedance measurements were normal and the CI was successfully activated 4 weeks postoperatively. <br><br>CONCLUSIONS: Clinicians and patients should be aware of the risk of displacement of the CI magnet after (minor) head injury. Young boys tend to have a higher risk for this complication.<p />  <p>Language: en</p>
