A cochlear implant is a small, surgically implanted electronic device that helps people with severe to profound hearing loss who do not benefit enough from hearing aids. Unlike hearing aids, which amplify sound, a cochlear implant directly stimulates the auditory nerve, allowing the brain to process sound signals more effectively. Cochlear implants can significantly improve hearing, speech understanding, and quality of life.
A cochlear implant bypasses damaged parts of the inner ear and directly stimulates the auditory nerve. The device has two parts:
External sound processor: Captures sound, converts it into digital signals, and sends it to the implant.
Internal implant: Surgically placed under the skin, it converts signals into electrical impulses that stimulate the auditory nerve.
Cochlear implants are recommended for:
Hearing tests, speech evaluations, and imaging scans help determine eligibility.
The surgery takes 2–3 hours under general anesthesia. The surgeon places the implant behind the ear and inserts electrodes into the inner ear (cochlea). Most patients go home the same day or after an overnight stay.
Recovery is usually quick, with mild discomfort for a few days. The implant is activated 2–6 weeks after surgery once healing is complete. Intensive follow-up and auditory rehabilitation therapy are crucial for the brain to learn how to interpret new sound signals.
Hearing aids amplify sounds and rely on the remaining natural hearing ability.
Cochlear implants directly stimulate the auditory nerve, helping even those with very little or no functional hearing.
Cochlear implants improve speech understanding, allow better communication without lip-reading, and help children develop normal speech and language skills. Many patients can use the telephone and enjoy music again after rehabilitation.
Risks are generally low but may include infection, dizziness, implant failure, or (rarely) nerve injury. Choosing an experienced ENT surgeon helps minimize risks.
Most patients experience significant improvement in hearing and quality of life. Success depends on age at implantation, duration of hearing loss, and participation in post-surgery rehabilitation. Children implanted early often develop near-normal speech and language.
If you or your child has severe hearing loss and hearing aids are not effective, our ENT & Cochlear Implant Program at Baby Memorial Hospitals offers advanced evaluation, surgery, and rehabilitation to restore hearing and communication.
