Extradural haematoma presenting as a contralateral sixth nerve palsy after cochlear implantation

Abstract Intracranial complications after cochlear implantation are rare. The authors present the case of a 13 month old boy with a contralateral abducens nerve palsy following cochlear implantation that led to the diagnosis of an extradural haematoma on computerised tomography scanning. The abducens palsy resolved after evacuation of the haematoma and the patient made an excellent recovery. The literature is reviewed and the mechanism of injury discussed.
