S. Anand Babu, 37, an employee of Aavin, from Mathur near Kallakurichi is happy to see his five-year-old son Kovegan call him “Appa”. Earlier, the child did not respond when his name was called and was unresponsive to everyday sounds.

Born with bilateral profound sensorineural hearing loss, the child could not speak till the age of four. But all that changed when he underwent free cochlear implant surgery under the Chief Minister’s Comprehensive Health Insurance Scheme at the Kallakurichi Government Medical College and Hospital (KGMCH) in 2024.
