Cochlear Implants: Bilateral versus Unilateral

Sensorineural hearing loss (SNHL) involves damage either to the cochlea or to the neural pathways from the retro cochlea to the brain. The most common form of SNHL occurs when the cilia lining the cochlea area are lost and there is no way for sound waves entering the cochlea to be transformed into nerve impulses. If the neural elements that transmit information from the cochlea to the auditory cortex of the brain are intact and functional, it is possible to stimulate the auditory nerve with a prosthetic cochlear implant device designed to perform the function of cochlear hair cells, thereby restoring some degree of hearing.
