What degree of hearing loss qualifies a child for a cochlear implant?

Hearing loss in children can be either sensorineural or conductive, and the type and severity both matter when deciding if a cochlear implant is the right option. A cochlear implant is generally indicated when a child has severe-to-profound sensorineural hearing loss, typically with thresholds greater than 70-90dB, and hearing aids are no longer giving adequate benefit for speech and language development.

It's worth understanding that the degree of hearing loss alone isn't the only factor here. Qualifying for an implant depends just as much on how well the child is actually performing with hearing aids. Even at profound levels of hearing loss, the real deciding factor is whether hearing aids are helping the child develop speech and language skills. If they're not providing meaningful benefit despite proper fitting and a fair trial period, that's when a cochlear implant becomes the appropriate next step.

Timing matters a great deal for the best outcomes. Ideally, cochlear implant surgery should be done before the age of 2, since this is when a young brain has the greatest capacity to learn spoken language. As children get older, this window of neuroplasticity gradually narrows, making it harder for the brain to fully adapt to and interpret the new signals from the implant. Early evaluation and timely intervention, therefore, play a key role in giving a child the best chance at developing strong speech and language abilities.
