Cochlear Implant – An Overview
A cochlear implant device is mainly consisting of several external and internal parts that allow it to transmit outside noise into the auditory nerve system.
Cochlear Implant Device
The device is composed of microphone – One, or multiple, microphones on the outer shell receive the sounds from the environment, a speech processor – This component acts by filtering background noise from audible speech and then transmits the audible speech into electrical signals that are then sent to transmitter through a thin cable, transmitter – This is a magnetic coil-assisted part of the device and is situated behind the external part of the ear which uses electromagnetic induction to send the sound signal through the skin and into the internal receiver, receiver and simulator – This is attached to a bone inside the ear (percutaneous) and converts the sound signals received from the transmitter into the array of electrodes by converting them into electrical impulses, electrode array – This consists of around 22 electrodes which are arranged in the cochlea of the ear and send the electric impulses to the nerves and then on to the brain through the auditory nerve system.
Cochlear Implant procedure
The cochlear implant device is surgically implanted using either general, or local, anesthesia. The surgery requires clearing a small area of the scalp behind the ear by shaving the hair. An incision is made in that region and then a hole is made in the mastoid bone behind the ear. This hole is used to fit the external part (simulator/receiver) of the device while the electrode array is fixed inside the cochlea (inner ear).
The implant is activated after a period of about 1-4 weeks by connecting a sound processor to the internal device with a strong magnet. The cochlear implant surgical procedure will usually be followed by a speech and auditory therapy regimen depending on the age and severity of the hearing disability, which varies from person to person.
