Final answer:
Sensorineural deafness occurs when there is a failure to transmit neural signals from the cochlea to the brain. Cochlear implants are a treatment option for this type of hearing loss.
Step-by-step explanation:
Sensorineural deafness occurs when there is a failure to transmit neural signals from the cochlea to the brain. It is caused by damage or degeneration of inner ear structures, such as the cilia and nerves. One example of a disease that results in sensorineural hearing loss is Ménière's disease.
Hearing aids cannot treat sensorineural hearing loss, but cochlear implants can be used as a treatment option. Cochlear implants stimulate the auditory nerve directly and transmit information to the brain. Over 100,000 cochlear implants are currently in use.
