Noninvasive management of cochlear implant's inner magnet displacement after magnetic resonance

Laryngoscope. 2013 Mar;123(3):783-6. doi: 10.1002/lary.23668. Epub 2012 Oct 19.


MRI is a widespread and greatly helpful diagnostic tool, yet its use on cochlear implant patients is restricted by the presence of an inner magnet. We report on a case of magnet dislodgment after 1.5T MRI in a 31-year-old female with a Hi-Res 90K cochlear implant. In this case, it was possible to implement an alternative, totally noninvasive approach based on an external manual repositioning rather than a surgical procedure of the displaced magnet.
