Zusammenfassung: | 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
The introduction of magnetic resonance imaging (MRI)‐compatible cochlear implants and bone anchored hearing aids, may lead to more opportunities for confusion regarding the MRI compatibility of these devices. This case report describes two patient cases where adverse consequences were reported. The text also explores the need for improved patient education, simplified MRI guidelines, as well as the development of MRI‐compatible technology. |
