Cochlear Implantation in Children with Cochlear Malformation.

Cochlear implantation (CI) has proven to be an effective treatment for severe bilateral sensorineural hearing loss (SNHL). Inner ear malformation is a rare anomaly and occurs in approximately 20% of cases with congenital SNHL. In cases with cochlear malformation, CI can be successfully performed in nearly all patients, the exceptions being those with complete labyrinthine and cochlear aplasia. It is important to evaluate the severity of inner ear deformity and other associated anomalies during the preimplantation radiological assessment in order to identify any complication that may potentially occur during the surgery and subsequent patient management.
