OBJECTIVE: Cochlear implantation is a successful method of auditory rehabilitation. This procedure has been associated with facial nerve and vestibular end-organ stimulation suggesting potential for extra-cochlear stimulation. The objectives of this study were to investigate the potential relationship between cochlear implantation and seizure activity in the pediatric implant population.
METHODS: Local Research Ethics Board approval was obtained. The Hospital for Sick Children's Cochlear Implant Database from 1998 to 2011 was retrospectively reviewed. Based on a multidisciplinary team, patients who received a diagnosis of seizure disorder or had been investigated for seizure-like activity were identified and reviewed.
RESULTS: Fifteen children from a group of 816 pediatric cochlear implant users were identified as having suspected seizure-like activity. Eventually 10 children were found to have seizures based on an evaluation by a pediatric neurologist and an electroencephalogram. Of these 10, only 3 children had new onset of seizures after cochlear implantation and 2 of these 3 suffered from global developmental delay and other medical comorbidities. No definite temporal connection was found between cochlear implant use and seizure activity.
CONCLUSIONS: Cochlear implantation in the pediatric population continues to be a reliable and safe intervention for children. Overall the prevalence of post implantation seizure disorders in our population (0.37%) is lower than that of the overall population (0.5-1%). The presence of new-onset seizure activity following cochlear implantation is unusual and while there are theoretic possibilities of how a cochlear implant could be implicated in initiating seizures we were unable to find evidence to support this association.
