The Cochlear Implant
نویسنده
چکیده مقاله:
The studies on cochlear implants have been conducted in the United States, Austria, Brasil, France, Finland, and some other countries. Up to now, this technique does not seem to have a wide spread application. Indeed it can only apply cases of deafness still presenting sufficient neural remnants to transmit the message. Moreover, the patient must be totally deaf( quasi complete loss of har cells), because any auditory remnant, even minimal, can be exploited by classical electro-acoustic amplification, which will(until now) give, in this sort of case, better results than cochlear implant, especially as the cochlear implant destroys any remaining sensory structures. Furthermore, the nervous message thus obtained is very different from the normal one, so that the interpretation is extremely difficult and require training, certainly over several years, and ev<.!n several ten of years, as is the case for rehabilitation for quasi-totally deaf children with the present technique. In any case, it is the direction of research which must be explored precisely and scientifically; the future will tell us whether this project must be abandoned or developed.

Cochlear implants are first true bionic sense organs Like human inner ear hair cells they convert mechanical sound energy into electrical impulses. Cochlear implants are not hearing aids which merely amplify mechanical sound waves and increase their energy content Otter et al have shown that in the normal auditory nerve in young people there are approximately 35,000 nerve fibres; they concluded...
متن کاملParental Attitude toward the Consequences of Cochlear Implantation in Children referred to the Besat cochlear implant center in Hamadan, 2019.
Introduction: Cochlear implantation is a cure for hearing impaired or deaf children who can't use hearing aids. Parental attitude to post-cochlear implications can be effective in the process of child rehabilitation. Therefore, the aim of this study was to investigate the parents' attitude towards the consequences of cochlear implantation in children referred to the Besat cochlear implant cente...
متن کاملA cochlear implant electrode.
This study has shown that an electrode array can be passed along the hold length of the cochlea if it is inserted through and opening in the scala tympani of the apical turn. The electrode must have the appropriate mechanical properties and some of these were stiffness and extensibility. The electrode and operative approach should be helpful in stimulating the terminal auditory nerve fibres on ...
