Cochlear Implants

A cochlear implant (CI) is a surgically-placed electronic device that bypasses damaged inner-ear hair cells and directly stimulates the hearing nerve. It is offered to people with severe or profound sensorineural hearing loss who don't get enough benefit from hearing aids. In India, CI is now available at many tertiary centres, and government schemes make it free or heavily subsidised for eligible children.

Who's a candidate

• Children with severe/profound bilateral hearing loss — ideally implanted by age 1–2 for best speech and language outcomes. Every month matters.
• Adults who become profoundly deaf post-lingually — CI restores speech understanding in most.
• Single-sided deafness and some complex cases — specialist-decided.
• Not everyone benefits equally — pre-op assessment includes audiology, speech/language, imaging, and counselling.

In India — access and cost

• CI is expensive (device + surgery + years of rehabilitation).
• Central government ADIP-CI scheme covers implantation for children under 5 with profound hearing loss meeting eligibility.
• State schemes — Kerala, Tamil Nadu, Karnataka, Maharashtra, and others have additional coverage.
• Ayushman Bharat and state insurance may cover part of the cost in empanelled hospitals.
• NGO and corporate-CSR support help many families bridge the gap.
• Ask social workers at paediatric ENT departments — they know current scheme details.

What to expect

• Surgery is day-care or short stay; the implant is "switched on" about 3–4 weeks later.
• Early sounds will feel robotic or mechanical — the brain takes weeks to months to adapt.
• Intensive speech therapy and auditory-verbal therapy are essential, especially in children, for 1–2+ years.
• Regular mapping (programming) sessions at the CI centre.
• Device care — don't wear the external part in water (unless waterproof), protect from impact, use anti-theft strings in young children.
• MRI compatibility depends on the implant model — tell every doctor about the implant before imaging.

Key decisions

• Early diagnosis — universal newborn hearing screening catches congenital deafness early; if your newborn failed the OAE, push for confirmatory testing and a decision by 6 months.
• Don't delay hoping hearing aids will improve; in profound loss, time to implant is the strongest predictor of speech outcome.
• Choose a centre with a paediatric ENT, audiologist, speech therapist, and rehabilitation team together — not just the surgery.
