Here are symptoms, effects and procedure of cochlear implants.

Hi! I am Dr. Manish Prakash senior ENT consultant at Mayom Hospital, Gurgaon. Today we are going to talk about Cochlear Implants. Cochlear Implants are the boom for the deaf. They are primarily indicated for severe to a profound Sensorineural Hearing loss in children and adults.

Hearing loss is of two types Conductive Hearing loss and Sensorineural hearing loss.

Conductive Hearing Loss primarily means that the sound is not able to reach inside the inner ear into the cochlea and that is why it is called as Conductive Hearing Loss whereas Sensorineural hearing loss means that the sound is reaching into the cochlea but because to the damage in the cochlea hair it does not reach to the auditory nerve and it cannot reach to the brain.

Cochlear implants are mainly indicative for the treatment of Sensorineural hearing loss. Cochlear implants consists of two parts. One is internal component and the external component. Internal component is the surgically implantable electrode which is inserted by a surgery inside the cochlea which happens to reside behind the ear. The external part is a processor which is also having a microphone and a transmitting coil which is a house behind the ear and is supposed to capture all the sound and transmit it to the electrical signals. Thereby the signals enter to the cochlea via the electrode and these signals are transmitted through the auditory nerve to the brain. Cochlear implants is majorly for pre lingual children. Pre lingual mean before the development of the language and children who are born deaf and children under 8 years of age are good candidates for such kind of intervention and procedure and also children who are post lingual deaf which means that after the acquisition of language. Afterwards who become deaf post lingual children and adults are also good candidates for the cochlear implantation program.
