Cochlear implantation in children with keratitis-ichthyosis-deafness (KID) syndrome: outcomes in three cases.

Three children with keratitis-ichthyosis-deafness (KID) syndrome received cochlear implants at the Royal Victorian Eye and Ear Hospital. KID syndrome is a rare genodermatosis associated with mutation of the connexin-26 gene with characteristics affecting skin, hair, vision and hearing. Ichthyotic involvement of the ear canal epithelium and associated non-erosive keratosis obturans complicate hearing assessment and aid fitting. The tendency to eczematous dermatitis and otitis media is an additional problem with cochlear implantation. All cases have required additional medical management, however the outcomes show that the cochlear implant can be effective in these patients.
