However, the result is not the same as normal hearing.Current thinking is that the inner ear responds to sound by at least two separate ways.One theory, the place theory, says the cochlea responds greater to a simple tone at one place along its length. Adults with little or no experience with sound tend to benefit less from cochlear implants.Mayo Clinic does not endorse companies or products. For example, they sent the lower pitches to the area of the cochlea where it seemed more responsive to lower pitches.
Cochlear implants may be placed in one ear (unilateral) or both ears (bilateral). Another theory is that the ear responds to the timing of the sound.Researchers, following the place theory, devised implants that separated the sound into groups. This process is ongoing and is best achieved by wearing the speech processor continuously during waking hours.Results of cochlear implant surgery vary from person to person.
However, research with this device began in the 1950's.

And recent improvements in technology have made cochlear implants accessible to a new set of deserving patients—those with some residual hearing. Factors that can affect the outcomes of cochlear implantation include the age when hearing was lost, and the length of time between hearing loss and the cochlear implant surgery.For children, the best results generally occur with getting a cochlear implant at a young age.For adults, the best results are generally associated with a shorter period of profound hearing loss before cochlear implantation. Colin Driscoll, M.D., Otolaryngology - Head and Neck Surgery, Mayo Clinic: "One of the more exciting things that's been developed in the last number of years is surrounding the concept of preserving the hearing that people currently have." Even individuals with severe or profound "nerve deafness" may be able to benefit from cochlear implants.Many things determine the success of implantation. This means you or your child will be in a sleep-like state during the procedure. I am stunned by her success and inspired too, to seek help myself. I know many people who have had a cochlear implant, and all have benefitted to some extent, but my Friend has been in a league of her own.

Risks of cochlear implantation can include:Cochlear implant surgery is done under general anesthesia. Vivien Williams: If hearing aids don't work for you, cochlear implants might.

Cochlear implants can improve their communication and quality of life. And they sent higher pitches to the area more responsive to high pitches. Thus, they used several channels and electrodes spaced out inside the cochlea. Though the cochlear implant is very safe, it comes with various complications and risk factors. Successful in a wide range of patients, including the elderly, cochlear implantation is now the standard of care for treatment of severe to profound bilateral sensorineural hearing loss.
The brain interprets those signals as sounds, though these sounds won't be just like normal hearing.It takes time and training to learn to interpret the signals received from a cochlear implant. And they keep on hearing, a long-term study shows. However, the high success rates with cochlear implants make the change worth it for users. A big qualification is whether or not the implanted person is willing to put in the work to optimize the cochlear implant's technology.

These electric currents activate the nerve, which then sends a signal to the brain. Success Factors for a Cochlear Implant It is difficult to accurately predict performance with a cochlear implant, but indicators for success have been reported: Postlingually deafened adults with a shorter duration of deafness tend to achieve the highest speech perception scores. Since there were also timing theories, researchers devised implants that made the sound signals into pulses to see if the cochlea would respond better to various kinds of pulses.Most modern cochlear implants are versatile, in that they are somewhat capable of being adjusted to respond to sound in various ways. A doctor will conduct an evaluation that may include:Your surgeon will make a cut (incision) behind your ear, and form a small hole in the portion of skull bone (mastoid) where the internal device rests.Your surgeon will then create a small opening in the cochlea in order to thread the electrode of the internal device. A cochlear implant isn't a hearing aid which amplifies sound.

Cochlear implants in both ears have started to be used more often to treat bilateral severe hearing loss — particularly for infants and children who are learning to speak and process language.Adults and children who are as young as six to 12 months old can benefit from cochlear implants. March 24, 2005 -- Most deaf kids learn to hear after getting cochlear implants.
Some types of cochlear implants have one external unit that has a speech processor, microphone and transmitter combined (lower left), while others have these as separate external parts (upper left and on right).A cochlear implant is an electronic device that partially restores hearing.
The Cochlear Implant Program at the Children's Hospital of Michigan is a multidisciplinary team servicing pediatric cochlear implant recipients since 1987.
