About Cochlear Implants
A cochlear implant is a small, complex electronic device that can help to provide a sense of sound. People who are profoundly deaf or severely hard-of-hearing can get help from them. The implant consists of two parts. One part sits on the outside of the body, behind the ear. A second part is surgically placed under the skin.
An implant does not restore normal hearing. It can help a person understand speech. Children and adults can benefit from them.
National Institute on Deafness and Other Communication Disorders
It sits within Ear, Nose and Throat.
The lead U.S. institute for this subject is the National Institute on Deafness and Other Communication Disorders.
When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.
Research on Cochlear Implants
453 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.
What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
