With sensorineural hearing loss, hair cells in the cochlea or (rarely) the auditory nerve are damaged. Sound vibrations can not be converted into electrical signals, which leads to the impossibility of recognizing sounds by the brain.
With a small, moderate or even moderately severe hearing loss, sound will be perceived by the surviving hair cells.
The most common causes of sensorineural hearing loss in children are hereditary hearing impairment, hypoxia, high bilirubin level, viral infections of the mother during pregnancy, meningoencephalitis, taking ototoxic drugs, etc. Hearing loss - from I degree to deafness.
The dummy unit will significantly improve the partially left auditory function due to more intense stimulation of the hair cells.
Implants of the middle ear
Implants of the middle ear are used for mild, moderate and severe hearing loss.
When a significant part or all of the hair cells died, the hearing aids are often ineffective. Then a cochlear implant is used which, taking sounds, converts them into an electrical signal and transmits directly to the nerve, bypassing the structures of the affected cochlea.
