Pediatric Cochlear Implants

Pediatric cochlear implants have parts located on both the inside and the outside of your child’s ear sending sound signals to their brain.

What are Pediatric Cochlear Implants?

Cochlear implants are small, electronic devices that are inserted surgically into the inner ear and under the skin behind the ear to provide a sense of sound for someone who is profoundly deaf or hard of hearing. They include an external piece that sits behind the ear and an internal piece that is placed surgically under the skin.

Cochlear implants do not correct the cause of hearing loss and restore natural hearing. However, they do provide access to sound and spoken language to a patient who would otherwise be deaf.

What are the benefits of Pediatric Cochlear Implants?

Cochlear implants are different than hearing aids; a hearing aid only amplifies sound. A cochlear implant bypasses your deaf child’s non-functioning inner ear and provides direct stimulation of the auditory nerve. The auditory nerve transmits those signals to the brain, which recognizes them as sound

Frequently Asked Questions

  • Is my child a candidate for a cochlear implant?

    If your child is deaf or severely hard of hearing, a cochlear implant may expose them to sound and improve their ability to develop speech and language skills. The multidisciplinary team of experts at UT Pediatric Cochlear Implant Program at Children's Health work with you and your child to evaluate whether a cochlear implant can make the difference between sound and silence.

    Cochlear implants are available for children age 6 months or older. Studies show that younger children most often have the best results when they are exposed to sound during the critical period when speech and language skills develop – when possible, before they are 18 months old.

    Your child may be a candidate for a cochlear implant if he or she has:

    • Severe to profound hearing loss in both ears
    • Little or no benefit from hearing aids
    • No health conditions that eliminate it as an option
    • Lack of progress in auditory skill development
  • How do cochlear implants work?

    In a typical ear, sound makes the eardrum and middle ear bones vibrate. Those vibrations are then converted into electrical signals by the cochlea and sent to the brain, which recognizes them as sound. Cochlear implants have parts located on both the inside and outside of your child’s ear to send sound signals to their brain and mimic this process.

    Cochlear implants consist of four main parts:

    • A microphone to pick up sounds in the environment
    • A speech processor to arrange those sounds into signals
    • A transmitter that takes signals and converts them to electronic impulses
    • An electrode array that takes the impulses and sends them to different parts of the auditory nerve

    The speech processor is attached externally and resembles a traditional, behind-the-ear hearing aid. It contains a microphone and computer that recognize sound and converts it into electrical signals.

    The electrical signals are routed to the transmitter, which is about one-inch around and attached to the side of your child’s head with a strong magnet. The transmitter then sends the signals through your child’s skin to a receiver and on to the electrode array inside your child’s inner ear. This stimulates the auditory nerve and allows your child to recognize sound.
