[Medical devices correcting the deafness: Hearing aids and auditory implants].

The management of deafness has become a major public health issue as their lack of detection has a deleterious effect in children and increases the risk factors for aggravation of other pathologies in adults. The detection of deafness remains a real challenge: in the newborn, systematic screening at birth is a good strategy, in adults, much remains to be done. The functional rehabilitation of deafness is based on the use of hearing aids by aerial or bone conduction or of auditory implants. There are three types of auditory implants available: bone anchored hearing implants, middle ear implants and cochlear implants. Many actors, in particular social organizations, can intervene in the financial management of these medical devices.
