Cochlear implantation has been established as a medical treatment for children with profound or severe-to-profound hearing loss who do not derive benefit from hearing aids. Multichannel cochlear implants first received FDA approval for use in children in 1990. The implant consists of external components and a surgically implanted internal device. The external portion of the device includes a microphone, microprocessor-based speech processor, and a radio frequency transmitting coil. The implanted portion houses a radio frequency receiver coil, microprocessor-based stimulator, and multichannel electrode array. Cochlear implants (CI) do not restore normal hearing, but provide access to sound at a level similar to that of less hearing-impaired patients who are successful hearing aid users.
