A cochlear implant is very different from a hearing aid. Hearing aids amplify sounds so they may be detected by damaged ears. Cochlear Implants bypass damaged portions of the ear and directly stimulate the auditory nerve. Signals generated by the implant are sent by way of the auditory nerve to the brain, which recognizes the signals as sound. Cochlear Implants are surgically placed electrical devices that receive sound and transmit the resulting electrical signals to electrodes implanted in the cochlea of the ear. The signals stimulate the cochlea, allowing patient to hear.

Children and Adults

Use of a cochlear implant requires both a surgical procedure and significant therapy to learn or relearn the sense of hearing. Surgical implantations are almost always safe, although complications are a risk factor, just as with any kind of surgery. An additional consideration is learning to interpret the sounds created by an implant. This process takes time and practice. Speech-language pathologists and audiologists are frequently involved in this learning process. Before implantation, all of these factors need to be considered.

Yes, a cochlear implant allows you to hear more or less normally. The implant is made up of two major components: an external processor and an inside receiver. The external processor, which is worn outside the ear, receives the sound impulses. The internal implant is implanted in the ear under the skin and transfers the collected sounds to the auditory nerve.( Hearing nerve) which transmits the impulses to the brain. The implants send electrical signals to the auditory nerve. These impulses are interpreted as sound by the brain. Patients may require speech therapy to learn how to properly interpret these sounds. But most individuals with normal brain function are able to interpret them after good therapy and rehabilitation. Of course with newer and newer technology in implants, we are getting better sound impulses transmitted.

The cochlear implant functions in place of the damaged cochlear. The cochlear is a tiny snail-shaped organ in the inner ear. Its function is to modify the sound waves into electrical impulses that the brain can understand. The cochlear implant works by directly stimulating the auditory nerve with electrical signals, bypassing the damaged cochlea. These signals are subsequently interpreted by the brain as sound. Patients with cochlear implants can regain their hearing and improve their quality of life.

A cochlear implant's success rate varies depending on the individual and the reason for their hearing loss. Cochlear implants, in general, have a high success rate in restoring hearing to people with profound hearing loss. A study published in the American Journal of Otolaryngology discovered that in patients with severe to profound hearing loss, cochlear implant surgery had a success rate of more than 90%. The study also discovered that patients' quality of life improved significantly following the procedure.

With good care and maintenance, cochlear implants can survive for many years. Every five to seven years, the external processor may need to be replaced depending on wear and usage. The internal receiver has a lifespan of 20 years or more. Regular visits to the audiologist and surgeon can assist ensure that the implant works properly and lasts. To maximize the life of the cochlear implant, it is critical to follow the suggested care and maintenance instructions.
