What's a Cochlear Implant?

Cochlear implants are electronic devices that stimulate the cochlea and provide a sense of sound for people with hearing impairments. It bypasses the damaged hair cells and sends auditory signals to the brain. A cochlear implant has two parts; external and internal. The external part uses a microphone to pick up sounds; it then sends the sound signal to the internal part of the cochlear implant. The internal part is surgically implanted under the skin behind the ear.

Hearing aids cannot help people with severe hearing-loss and inner-ear damage. Such individuals can benefit from cochlear implants. While hearing aids can provide louder sounds, cochlear implants provide sound signals to the brain.

With cochlear implants, normal hearing is not restored. But it can provide enhanced hearing by increasing awareness of sounds in the environment.

  2. A small incision is made behind your ear.
  3. The surgeon lifts the tissue flap to provide a surgical area for drilling into the skull bone.
  4. The internal part of the cochlear (receiver) is placed into the area that was drilled out. Along with an electronic array.
