Raghunandhan, P. Krishnan, Srividya Prashanth, Sathiya Murali, Mohan Kameswaran] The successful outcome of a cochlear implant habilitation program depends upon a multitude of vital factors, including the avid cooperation of the cochlear implantee, committed participation of the parents/family members and total dedication of the habilitation team of implant audiologists and auditory verbal therapists. In a rare situation, where the implantee's performance is suboptimal or poor inspite of successful implantation, anxious moments engulf the parents and the implant team, with the morbid fear of a device failure lingering at the back of their minds. We report such an incident in a 13-year-old cochlear implantee, who was an excellent cochlear implant performer for 8 years, following which she had rapid deterioration of her auditory verbal skills within the next few weeks. The hidden etiology, was the inconspicuous migration of the internal magnet of the Receiver-Stimulator Coil placed in the mastoid temporal bone of her skull, due to unexplained reasons. We share our experience with the diagnosis and management of this condition and review the existing world literature on this rarely reported entity.
