Abstract
We performed cochlear implantation in 4 three-year-old children. Special attention was paid to skin incision and temporal bone drilling for device embedding. The skin flap viability and wound healing was good and we did not experience any wound infection nor flap necrosis after surgery. Patients exhibited significant improvement in detection of environmental sounds, and production of speech increased gradually. Although the language development of a perilingually deaf boy was excellent, that of the remaining congenitally deaf children was slower. Early decision and application of the cochlear implant is necessary for better development of the spoken language in profoundly deaf young children.
