Part 2 of 11 in Cochlear Implants in Children: From Candidacy to Classroom Success
The Silent Disability: Why Pediatric Hearing Loss Goes Undiagnosed
March 1, 2026
Dr. Dilpreet Bajwa chose to build her career around pediatric hearing loss and cochlear implants because, in her words, it is very close to her heart. In India, an estimated 1 to 3 of every 1,000 children are born with hearing loss, and with roughly 60,000 to 65,000 births a day, that is a large number of children arriving with a hearing deficit every single day. She expects a similar pattern in Africa, a fellow developing region where the same causes of hearing loss are common and just as likely to go unnoticed.
Why parents miss it
Hearing is one of six senses, and of all of them, its loss is the hardest for a family to see. A child who cannot hear will not learn to speak, or will speak with clarity that is hard to understand. Because the disability itself is invisible, it commonly goes undetected until the child is between two and five years old, sometimes later. Parents often conclude the child is simply a late talker who will eventually catch up, a belief that becomes especially convincing when the child has moderate hearing loss and does develop some speech, just not enough to be clearly understood.
Restoring hearing is not the same as restoring language
Dr. Bajwa is explicit that the objective of treatment is broader than making a child hear again. The aim is to provide enough auditory access for the child to build language, speak clearly, and participate socially, so that the child can live a normal life. That distinction matters clinically: a family that only wants their child to react to sound will make different decisions than one that wants their child to hold a conversation, and the age at which treatment starts determines which of those outcomes is realistic.
A pattern she expects to repeat across Africa
Dr. Bajwa delivered this masterclass to doctor partners across India and Africa specifically because she believes the underlying pattern, a preventable or treatable condition that stays hidden until speech delay forces a diagnosis, repeats across developing health systems generally. Raising that awareness among primary physicians and family doctors, who are often the first to hear a parent's concern, is itself part of the intervention.

FROM THE LIVE Q&A
Dr. Ivan (Uganda)
Can the implant be done for those who have hearing loss at a later age, in adulthood?
Dr. Dilpreet Bajwa
Yes, and adult implantation is increasingly common. Someone with progressive hearing loss who already developed language accepts a cochlear implant beautifully, with no contraindication. If a person was born deaf and is now 40, an implant is still possible, but the chance of developing meaningful speech is questionable, unlike someone who lost hearing after already learning to speak.

Frequently Asked Questions
What about a 10-year-old child, or someone in their 20s, born with a hearing disability? Since the neuroplasticity window has closed, what benefit can they expect?▼
The definition of success changes with age. Parents of a 2 or 3-year-old want the child to talk, and that is achievable up to about four and a half or five years of age. A 20-year-old implanted for the first time will mainly gain sound awareness, enough to notice a car horn on the road, rather than clear speech. A 10-year-old sits in between and may or may not develop good language. The exception is anyone who lost hearing after already developing speech, for example after an infection: they hear very well with an implant regardless of age.
Apart from children, what are the treatment options for adults who develop hearing problems later in life?▼
The first option is always a hearing aid. If it provides adequate, meaningful hearing, meaning the person can discriminate between words rather than just hear noise, that remains the treatment. Presbycusis, age-related hearing loss common in people 80 to 85 years old with no prior history, is a typical cause. If hearing aids only deliver noise without clarity, a cochlear implant is an option at any age.
Will it be useful for adults with hearing loss due to cancer such as chronic myeloid leukemia?▼
Absolutely. Chronic myeloid leukemia and even chronic kidney disease are not contraindications, because CML is an indolent, slow-moving disease. As long as the patient is medically stable and vaccinated beforehand, implantation can significantly improve their social interaction and quality of life.
For international patients, for example from an African country, how is long-term follow-up and device calibration handled if there is a local shortage of professionals?▼
Programming is now available online because most modern devices have built-in Bluetooth. An audiologist can connect through an app on a laptop or phone and wirelessly program or calibrate the device remotely, in much the same way as this Zoom masterclass, without the patient needing to travel back.
Regarding affordability, what does the surgery and device cost, and is it covered by insurance?▼
In India, cochlear implants are not covered by insurance, and the device is expensive, so CSR funds and government programs are used to support Indian families. Nothing equivalent currently exists for international patients. Paid out of pocket, surgery including the device starts at around 14,000 US dollars and can go up to 36,000 US dollars for high-end models, with cost driven mainly by MRI-compatible magnet strength, auto-programming that adjusts to noise every few seconds, and built-in Bluetooth.
Why do parents often miss the early signs of hearing loss?▼
Because the disability itself is invisible, it commonly goes undetected until the child is between two and five years old. Parents often conclude the child is simply a late talker who will eventually catch up, a belief that becomes especially convincing when the child has moderate hearing loss and does develop some speech, just not enough to be clearly understood.
Is restoring hearing the same as restoring language?▼
No. The aim is to provide enough auditory access for a child to build language, speak clearly and participate socially, so the child can live a normal life. That distinction matters clinically, since it shapes which outcomes are realistic at which age.
How does a family's goal change the treatment decisions they make?▼
A family that only wants their child to react to sound will make different decisions than one that wants their child to hold a conversation, and the age at which treatment starts determines which of those outcomes is realistic.
Why is raising hearing-loss awareness among primary physicians important?▼
Primary physicians and family doctors are often the first to hear a parent's concern, so raising awareness among them is itself part of catching a preventable or treatable condition before speech delay forces a diagnosis.
