Cochlear Implant Surgery for Congenital Hearing Loss

When traditional hearing aids no longer produce meaningful improvement, especially in cases of severe to profound hearing loss, the advanced option of cochlear implant surgery offers a transformative solution. At the heart of this service is our commitment to cochlear implant surgery for bilateral profound hearing loss, cochlear implant surgery for congenital deafness, and cochlear implant surgery for congenital hearing loss — ensuring patients receive the most appropriate intervention for their needs.

At the Juvekar Nursing Home, led by Dr. Meenesh Juvekar, specialists ensure that every candidate is thoroughly assessed and prepared for the best possible outcome. He is a trusted cochlear implant consultant in India, widely recognized for delivering excellent results in cochlear implant surgery for severe to profound hearing loss and for those needing cochlear implant surgery for bilateral profound hearing loss.

Air conduction hearing aids

Here the amplified sound is transmitted via the external auditory canal to the tympanic membrane. Types of Air conduction hearing aids

Body worn type: The microphone and amplifier with the battery are worn on the chest while receiver is at the ear. Used in severely deaf persons and congenital deafness. However, they are not very popular in today’s era.
Behind the ear: The whole hearing aid unit is worn behind the ear. Sound is transmitted to ear canal via a silicon tube or mould. This type is useful in moderate to severe hearing loss and cosmetically better. It is also easier to maintain.
In the Ear: The whole hearing aid is in a mould fitted in the ear canal. It is useful in mild to moderate hearing loss. Cosmetically, it is very good.
In the canal: This one is also called invisible hearing aid. The whole unit is in the external canal. It is useful in mild to moderate hearing loss. This has excellent cosmetic results.
Spectacle type: The unit is incorporated in the auricular part of spectacle frame. Not very popular.
Programmable hearing aids / Computerized hearing aids: These aids can be programmed according to needs of the patients and environmental conditions. They can be used in any degree of hearing loss.

Bone conduction hearing aids

The sound in these devices are transmitted to the inner ear by means of bone conduction vibrator placed on the mastoid process. Useful in severe congenital malformations.

Implantable hearing aids

Implantable middle ear hearing aids are a new category of hearing devices that work on direct drive principle. Instead of delivering acoustic energy into the external auditory canal, direct drive middle ear implant systems use mechanical vibrations delivered directly to the ossicular chain.

Environmental hearing aids:

They use the visual stimulus to alert the patient i.e. flash light on door bell ringing.

Mechanics of a hearing aid

Microphone: It fits into the hearing aid, collects sound energy and converts it into electrical energy.
Amplifier: Increases the amplitude of impulses generated.
Earphone: Converts electrical energy into sound.
Battery: Provides power supply.
Mould: Holds the hearing aid in place and acts like a seal.

Frequently Asked Questions (FAQs)

1. What is cochlear implant surgery and how is it different from hearing aids?

Cochlear implant surgery involves placing a surgically-implanted electronic device that bypasses damaged parts of the ear and directly stimulates the auditory nerve. Hearing aids, by contrast, simply amplify sound.
2. Who is a good candidate for cochlear implant surgery?

Ideal candidates are individuals with severe to profound hearing loss (or bilateral profound hearing loss) who receive minimal or no benefit from hearing aids. Both children with congenital hearing loss and adults who have lost hearing later in life may qualify.
3. What does the pre-operative evaluation include?

Before surgery, patients typically undergo audiological testing, imaging (CT/MRI), medical clearance, and counseling for themselves and their families to prepare for surgery and rehabilitation.
4. Will a cochlear implant restore “normal” hearing?

No, it does not restore natural hearing. It provides a different form of hearing and requires time, training, and rehabilitation for the brain to interpret the new sound signals.
5. Is rehabilitation required after cochlear implant surgery?

Yes. Post-operative auditory and speech training (cochlear implant surgery rehabilitation) is essential for improving hearing clarity, speech perception, and overall communication outcomes.
6. Can adults benefit from cochlear implant surgery even if they’ve had hearing loss for many years?

Yes. Adults with long-standing hearing loss who haven’t benefitted from hearing aids can still achieve significant improvements through cochlear implant surgery and proper rehabilitation.
