KNH activates cochlear implants in historic pediatric breakthrough

Kenyatta National Hospital (KNH) has achieved a historic medical milestone after successfully activating cochlear implant devices for children born with profound hearing loss, marking one of the most significant public-sector hearing interventions in Kenya.

The breakthrough followed months after complex surgeries were conducted, culminating this week in the long-awaited activation of the devices. For families, the moment was deeply emotional as parents watched their children respond to sound for the first time.

Tears of relief and joy filled the room as children reacted differently to the unfamiliar sensation. Some appeared startled, others became distressed, while several broke into visible smiles, responding to voices and surrounding sounds.

One mother shared how her daughter’s condition had forced her to constantly keep close for safety reasons. She recalled accompanying her child everywhere, even during simple hospital visits, due to concerns that she could not hear warnings or calls for help.

Dr Isaac Wahome, an audiologist at KNH, said such reactions were expected, noting that hearing through cochlear implants does not happen instantly. He explained that the brain takes time to interpret sound, especially for children who have never heard before.

“So far, reactions vary. Some children are shocked by the new sounds, others cry, and some show excitement and joy,” Dr Wahome said.

Hospital officials confirmed that 25 children have had their devices successfully switched on, with no complications reported so far. Many of the families had previously tried hearing aids, which proved ineffective, before being advised to pursue cochlear implants a procedure often out of reach due to its high cost.

KNH said the implants were donated, while the surgeries and follow-up care were covered under the Social Health Authority (SHA), making the programme accessible to families who would otherwise be unable to afford it.

The hospital has now appealed to partners, donors and benefactors to support the expansion of the programme, saying many more children remain in need of the life-changing intervention.

Hearing loss in children remains a major public health concern in Kenya, with an estimated 14 out of every 1,000 children affected by moderate to severe hearing impairment. Common causes include congenital infections such as rubella and toxoplasmosis, premature birth, neonatal jaundice, recurrent ear infections and exposure to certain medications.

Hospital officials say early intervention remains critical, noting that restoring hearing at a young age significantly improves speech development, learning and overall quality of life.
