The external parts include microphone, speech processor, and a transmitter. The implant is surgically placed under the skin behind the ear. The internal parts are a receiver and stimulator which are secured in the bone underneath the skin, and an array of electrodes wound through the cochlea which send impulses to the nerves in the scala tympani and then directly to the brain through the auditory nervous system. This procedure destroys any residual hearing the patient may have in the implanted ear; which is why single ear implantation is more commonly done.
