Who is a good candidate for the audience of the cochlear implant?

Kochlear implant hearing equipment is one type of medical possibilities for individuals who face deafness. Small recording devices can be implanted in adults or children and can help those who have a serious hearing loss in the digestion of sounds. The candidacy requirements are constantly changing because new research creates an increased understanding of the procedure of cochlear implant. However, some general candidacy criteria remain common, such as the following: deep deafness, sensorineural deafness and acceptance of psychological and auditory tests

deep and sensorineural hearing loss in both ears represents first -class adults. Deep hearing loss is the most serious and occurs when one does not hear sounds below about 95 decibels. In context, the average auditory person can distinguish sounds at about 20 decibels or higher levels. When these hair cells are damaged, the results of sensorineural damage. This type of hearing loss canE be the result of many different factors, including viruses, degenerative disorders, genetics or tumors. Sensorineural loss often leads to irreversible deafness.

Kochlear hearing devices of the implant help sensorineural hearing loss by direct stimulation of the hearing nerve of the inner ear by electric ear, thereby bypassing the hair cells needed for traditional hearing. The network of microphones, speech processors and transmitters placed on the outer ears in a tandem with surgically implanted electrodes and receivers create a perception of hearing for deep deaf.

There are several other general criteria for children, although each of them is subject to exceptions. For example, the United States of Food and Drug Administration set out in 2002 the recommended age instructions of one year or higher. Cochlear Surgical centers of the implant around the world, however, perform procedures in younger children under special circumstances. It is also recommended to pThe opponent's family environment, especially if such motivation involves participating in educational approaches that exceeds sign language. Medical diseases that may disrupt treatment or proven advances with other forms of hearing aids may exclude a child from the candidacy.

The same basic instructions apply to adults, and older individuals are likely to have to perform hearing tests such as a sentence recognition test. The prospect is provided to the hearing aid to perform the test. If an adult in this test score less than 50 percent, his chance of candidacy will increase. X -rays, MRI, psychological tests and counseling and routine medical examination should also be expected. The result will also be extensive subsequent services.

Comprehensive medical evaluation and objective information that represents both the cochlear Imppro of every potential candidate is the basis of advantages and critics. Audiologists and audiological test batteries can provide an invaluable insight into the level of deafness of the individual and jEho possible reaction to the auditory device for cochlear implant. The patient's linguistic skills before deafness and the level of comfort with the concept of renewed auditory language are important cognitive and psychological factors that should also obtain consideration. While the auditory device for cochlear implant cannot cure deafness, it can provide many patients with an improved level of life. The results and results will vary between individuals, so all medical and personal factors have the same meaning.
