Abstract
ObjectiveThere is increased confusion regarding MRI‐compatible CIs and BAHAs. This report describes two cases when patients underwent MRIs with non‐MRI compatible devices.ResultsOne 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.ConclusionsThis 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
