A cochlear implant is a surgically implanted device that bypasses damaged hair cells in the ear and provides electrical stimulation directly to the auditory nerve, giving patients who are severely hearing impaired or profoundly deaf the ability to hear. It is most beneficial for those who cannot be helped with a traditional hearing aid.
How Do Cochlear Implants Work?
A cochlear implant works differently than a hearing aid. Hearing aids amplify sounds so that a person with nerve damage can hear more clearly. Cochlear implants generate an electrical signal that the brain interprets as sound.
If you are experiencing severe to profound sensorineural hearing loss (the result of nerve damage to the inner ear) and can’t benefit from conventional hearing aids, you may be a prime candidate for cochlear implants.
These implants are most helpful in patients with solid language and communication skills and a hearing loss that occurred later in life. Younger children (typically between the ages of two and six) also benefit, since a cochlear implant exposes them to sounds during their formative learning years, while they are developing speech and language skills. Post-implantation therapy is a crucial component in the success of cochlear implants; learning to use them correctly takes time and effort.
