Performing MRI Scans on Cochlear Implant and Auditory Brainstem Implant Recipients: Review of 14.5 Years Experience

Abstract: Objective: To assess the complication rate of magnetic resonance imaging (MRI) using 1.5 T scanners on cochlear implant (CI) and auditory brainstem implant (ABI) recipients over 14.5 years. Methods: Prospective study conducted in a tertiary referral center for cochlear and auditory brainstem implantation, including patients with neurofibromatosis 2. The primary outcome was complications related to MRI scanning in implant recipients, including failure to… Show more

“…7a; [46,49,51]). Second, the magnetic field can induce significant heat and force, which may lead to pain and magnet dislocation, necessitating revision surgery [14,23,47,49]. Temporary magnet removal or correct securing of a head splint can be used to overcome these problems.…”

“…Zum einen führt der Magnet in der Empfangsspule zu erheblichen MRT-Signalartefakten, die bei Erreichen des Innenohres, des inneren Gehörganges und des KHBW die Beurteilung erschweren oder unmöglich machen. Diesem Problem kann jedoch durch eine geeignete Platzierung der Empfangsspule begegnet werden [46,49,51]. Die Platzierung der Empfangsspule erfolgte daher bei unseren Patienten mit einem Abstand von 9-10 cm zum äußeren Gehörgang.…”

“…Zum anderen kann die Krafteinwirkung des MRT-Magnetfeldes zu Schmerzen und sogar zur Dislokation des Magneten führen und Revisionsoperationen erforderlich machen [14,23,47,49]. Deshalb ist hier die Anlage eines kontrollierten Druckverbandes bei der Durchführung einer MRT-Untersuchung erforderlich.…”

“…Follow-up with magnetic resonance imaging (MRI) is thus required to assess growth of possible or obligate residual tumor cells. The inner ear and the IAC can be left out from the MRI artifact area of the magnet's receiver coil if the coil is placed further posterior and superior than in standard CI surgery [13,15,17]. In addition, a CI model should be chosen with a high compatibility of the magnet in the receiver coil.…”
