The cost of cochlear implant is mainly related to the material of cochlea. The cost of domestic cochlea is about 654.38+10,000 yuan, and that of imported cochlea is about 200,000 yuan, which is different from hospitals. There will be a slight difference between tertiary hospitals and secondary hospitals, but the difference in operation costs is not particularly large, mainly because of the different materials of cochlea.
Cochlear implant-artificial ear
This is an electronic device. The speech processor in vitro converts the sound into an electrical signal with a certain coding form, and directly stimulates the auditory nerve through the implanted electrode system to restore or rebuild the hearing function of the deaf. In recent years, with the development of electronic technology, computer technology, phonetics, electrophysiology, materials science and otomicrosurgery, cochlear implant has entered clinical application from experimental research. At present, cochlear implant has become a routine method to treat severe deafness to total deafness in all countries of the world.
