The clinic is headed by Mrs Asha Agarwal, Audiologist and Speech Therapist, also a consultant at Sir Ganga Ram Hospital who has devoted more than 40 years in the speech and hearing field. She has a credit of handling more than 1000 Cochlear implant cases audiologically and treated hundreds of cases with Stammering, Voice Disorder and Articulation Disorder.
Cochlear implant is a device which helps a deaf or a hearing impaired person to hear well when a regular hearing aid gives little or no benefit. A cochlear implant sends sound signal directly to the hearing nerve whereas a custom hearing aid only makes the sound louder. It has two parts: the internal implant which is surgically inserted in the cochlea by a cochlear implant surgeon and an external speech processor which send the signals to internal implant.
If a person is having hearing loss from 50dB to more than 90dB (moderately severe to severe sensori neural hearing loss and profound hearing loss in one or both ears) and is getting little or no benefit from hearing aids then is the candidate for cochlear implant.
Cochlear implant surgery can be done at any age if there are no other associated conditions. Cochlear implant surgery can be performed as minimum as in 6 months old children (if the baby has no other medical conditions and is healthy to undergo surgery). The results are best if it is done under 3 years of age.
A cochlear implant has two components:
1 Internal implant: Internal implant has receiver and electrodes. The receiver is housed in the temporal bone and electrodes are inserted in the cochlea.
2 External processor which send acoustic signal to internal implant. It has a microphone, speech processor and a transmitter. Microphone picks up the sound and then it send into speech processor and the signal is converted into electrical energy and transmitter send the signal to internal implant.
The internal implant is surgically fitted by a cochlear implant surgeon while the external implant is fitted post surgery by an Audiologist.
The external speech processor sends the acoustic signal to the internal implant and then via electrodes the sound signal is transferred directly to auditory/hearing nerve.
Two to three weeks post surgery external processor is activated by the audiologist. Audiologist slowly and gradually increases the current levels for sound as per the NRT responses (neural response telemetry, a procedure usually done in Operation theatre after electrodes are inserted and indicates the current level at which the nerve is getting stimulating. Initially a recipient might not respond appropriately. Babies and children tend to cry while switching on the processor to the first time as a response.
Speech Therapy or rehabilitation plays very important role in outcomes. Cochlear implant therapist (Auditory Verbal Therapist) trains the recipient to hear through the cochlear implant and help in speech & language development as per the norms. If a child receives appropriate training by a qualified therapist then they perform as per their peer group in terms of speech and language development.The outcome may vary depending on the age at implantation. It is a systematic approach which involves parents in the therapy program along with the recipients for better outcomes.
