Although hundreds of thousands of people have received Cochlear Implants, researchers have recently begun to question their efficacy and the appropriateness of their theatrical role under certain circumstances. Recent evidence shows that the implants tend to be more effective when done within the first class of birth or, when received after the patient has already genuine language before the onset of deafness.
Implantation is being found to be less appropriate for many in the deaf community.

It can easily be argued that one of the most impactful health check achievements relating to human perception in this past century was the culture of the cochlear implant for individuals with severe or profound deafness. Until 1975, the parallel behind-the-ear (BTE) hearing device was the primary medical device employ for hearing impaired adults and children. (NIH Fact Sheet, 1) It was designed to allow uninjured portions of the ear to detect sound. Although it served to amplify sound, it had little or no effect for those with more severe hearing loss.
