Abstract

We report a retrospective case of inner magnet migration, which occurred after 1. 5 Tesla Mri scanning in an adult recipient of a bilateral cochlear implant (Ci) despite a focused head dressing. The patient, bilaterally implanted with nucleus 5 Cis (Cochlear lTD, Sydney, Au-stralia), underwent a 1. 5 Tesla cholangio-Mri scan for biliary duct pathology. in subsequent days, a focal skin alteration appeared over the left inner coil. Plain skull radiographs showed partial magnet migration on the left side. Surgical exploration confirmed magnet twisting; the magnet was effectively repositioned. left Ci performance was restored to pre-migration level. The wound healed without complications. Thus, focused dressing does not prevent magnet migration in Ci recipients undergoing 1. 5 Tesla Mri. All patients should be counselled on this potential complication. A minor surgical procedure is required to reposition the magnet. nevertheless, timely diagnosis is necessary to prevent skin breakdown and subsequent device contamination. Plain skull radiograph is very effective in identifying magnet twisting; it should be performed systematically after Mri or minimally on all suspected cases.
