Topic Paper # 1 - Essay Example A Cochlear Implant is an electronic device which is implanted in the cochlea of the ear and is connected to a microphone on the outside through a speech processor and a transmitter. It works by converting sound vibrations into electrical stimuli, which provides a sensation of sound. Cochlear Implants are primarily recommended for those with a severe to profound hearing disorder. Among children and infants, a Cochlear Implant can help develop speech and communication skills. However, due to the long period of therapy required, its candidacy has to be determined on an individual basis and there is disagreement over its suitability for autistic children. Most cases of hearing impairment are due to loss of hair cell receptors in the inner ear, which limits the cochlea’s ability to transduce sound information from the environment to neural transmissions that can be interpreted by the central nervous system as auditory sensations (Copeland & Pillsbury, 2004). Since in such cases the nervous elements that transmit information from the cochlea to the brain remain intact, a Cochlear Implant is a viable option. The actual surgery to implant a cochlear implant is performed on an outpatient basis and requires about two to three hours of general anesthesia. However, once the prosthesis is implanted in the cochlea, there is an extensive process requiring aural habilitation with inputs from experienced audiologists and speech and language experts. Also, since the entire circuitry remains permanently attached to the patients, patients are required to take a number of precautions to avoid damage to the delicate device. The FDA-approved minimum age of implantation is one year. It is difficult to implant the device in younger children due to difficulty in properly testing the hearing in such young patients. Another concern is with patients suffering from multiple
