Cochlear Implants

What is a cochlear implant?

A cochlear implant is an electronic medical device that can directly stimulate the nerves within the inner ear, reproducing auditory stimulation for many patients with significant hearing loss. While some cases of hearing loss can be helped with hearing aids that amplify sounds, in some situations and forms of hearing loss this is not enough to provide better hearing for patients. Cochlear implants can reproduce the stimulation of the inner ear to the auditory nerve and help many people with this type of hearing loss.

Cochlear implants have an internal component that is placed beneath the skin, with a thin, delicate electrode that is surgically placed into the cochlea. An external component is worn that includes a microphone and processing system, which communicates wireless with the internal implanted device to deliver signals to the inner ear.


Over time, advances in cochlear implant technology, surgery and patient care has made them a highly successful solution for many adults and children with hearing loss. Research and improvement over decades has made the surgery very safe, and is often completed as an outpatient procedure. Advancements in design and technique have also made it possible to preserve acoustic hearing in combination with the electrical signals of cochlear implants.

Dr. Daniel Jethanamest is devoted to providing personal, excellent care to patients with hearing loss. With subspecialty training in ear surgery and a background in engineering and computer science, cochlear implants have been a natural focus of his clinical care and research pursuits. He has participated and published on improving surgical technique in cochlear implants and providing better hearing outcomes for users through technological innovation.
