Cochlear Implants

The cochlear implant (CI) program was created to serve children diagnosed with hearing loss who receive limited to no hearing aid benefit and whose families are dedicated to improving their child's communication mode.

Team members include pediatric otolaryngologist, Dr. Paul Bauer, M.D., otologist/neurotologist, Dr. Ricardo Cristobal, M.D., Ph.D., audiologists and speech-language pathologists with specialized training in the Auditory-Verbal Therapy approach. Other professionals may be added to a child's "team" if needed. These professionals may include physical therapy, occupational therapy or psychological services. We conduct monthly case conferences with CI physicians to discuss patients care.

What is a cochlear implant?

Cochlear implant deviceA cochlear implant has parts that are both inside and outside of the ear.

The inside part of the implant is a:

  • Receiver with a magnet
  • Wire attached to the receiver with small electrodes

The surgeon places the receiver under the skin, behind the ear. The receiver wire goes into the cochlea through an opening.

Cochlear implant deviceThe outside part of the implant has a:

  • Processor that goes behind the ear
  • Microphone that is in the processor
  • Cable
  • Coil

A cochlear implant can help children who:

  • Receive limited benefit with hearing aids.
  • Cannot hear speech and language with hearing aids.
  • Are in good health for surgery.
  • Have a family that understands the possibilities and problems with a cochlear implant.
  • Have strong family support for therapy and practicing every day at home.
  • Are around family members who consistently encourage listening and speaking.
  • Go to schools and attend activities that have lots of opportunities for listening and speaking.

What medical tests does my child need?

We do a full evaluation to find out if your child can have a cochlear implant. Some of these tests may include:

  • Tests done in X-ray to see what the ear and brain look like (magnetic resonance imaging-MRI; computed tomography-CT).
  • Tests to find out if there is a genetic cause for hearing loss.
  • Checkups by the ear-nose-throat doctor (ENT or otolaryngologist).
  • Visits with other doctors or specialists.

How does a cochlear implant work?

Cochlear implant – how it works

  • Your child wears the sound processor (microphone) behind the ear or on the shirt.
  • The microphone picks up sounds or speech.
  • The processor changes this sound into a special code.
  • The code travels up the cable to the coil and into the transmitter.
  • The coil transmitter sends the code to the receiver magnet under the skin.
  • This code then travels along the wire and through the cochlea.
  • The wire sends the code directly to the auditory nerve.
  • The auditory nerve sends the code to the brain.

How can I help my child do well?

Your child's success begins with you.

  • Make your home as quiet as possible so your voice is easy to hear.
  • Talk to your child. Your voice and words will help the brain's hearing center develop.
  • Sing to your child. Singing introduces rhythms and melodies. This helps develop the different tones in your child's voice.
  • Read, read, read to your child. The number of words your child knows when entering kindergarten is the most important measure of school success. A typical 5-year-old uses about 2,500 words. A book is your child's best toy for exploring the world and the words that go with it.
  • Get your child's attention first through sound. For example, call your child's name or start singing when you can't be seen. Watch for a reaction and then let them see you.
  • Talk close to your child's ear at a normal speaking volume. This screens out some of the background noises so your voice is easier to hear. It's better to get closer than to get louder.
