In your case, there is something called a cochlear implant, used for sensoralneural hearing loss which occurs with the mumps, which is an electronic device that is implanted behind the ear. A cochlear implant directly stimulates the auditory nerve fibers in the ear and has two parts,internal and external.The internal component is a receiver placed under the skin and the external components has a speech processor and a head-set which is worn behind the ear s a transmitter that is held in place over the implanted receiver by a little magnet.
