Ultrasound in Diagnosis of Magnet Dislocation of Cochlear Implants: A Retrospective Study in Patients With Surgical Magnet Repositioning and Preinterventional Ultrasound Examination

Conclusion: In CI-patients undergoing 1.5 Tesla MRI, partial magnet dislocation occurs much more frequently than complete magnet dislocation. The clinical suspicion of a dislocated cochlear implant magnet can be accurately confirmed by preoperative ultrasound. Thus, preoperative diagnostic ultrasound can be advocated as the diagnostic tool of first choice.
