OBJECTIVE
There is increased confusion regarding MRI-compatible CIs and BAHAs. This report describes two cases when patients underwent MRIs with non-MRI compatible devices.
RESULTS
One patient with bilateral Cochlear Osias experienced dislocation of both internal magnets after 1.5 Tesla MRI. Both magnets were outside the silastic sheath, with the left magnet flipped. A second patient with a legacy CI experienced similar internal magnet dislocation and inversion after 3 Tesla MRI.
CONCLUSIONS
This study describes internal magnet dislocation/inversion with the Cochlear Osia and a legacy CI after MRI. Our findings suggest the need for improved patient education and simplified radiology guidelines. Laryngoscope, 134:393-396, 2024.
目的
关于磁共振兼容的人工耳蜗和骨锚式助听器（BAHA）存在越来越多的混淆。本报告描述了两例患者在使用非磁共振兼容设备进行磁共振检查的情况。
结果
一位双侧 Cochlear Osias 患者在 1.5T MRI 后经历了双侧内部磁铁的脱位。两个磁铁都在硅橡胶鞘外，左侧磁铁翻转。第二位患有传统人工耳蜗的患者在 3T MRI 后经历了类似的内部磁铁脱位和反转。
结论
本研究描述了 Cochlear Osia 和传统人工耳蜗在磁共振检查后内部磁铁的脱位/反转。我们的发现表明需要改进患者教育和简化放射学指南。《喉镜》，134：393-396，2024。
