What is the ideal age to get cochlear implant surgery done?

The development of speech and language depends heavily on forming neural connections in the brain, and this only happens when the brain is exposed to auditory input early on. This is why universal newborn hearing screening plays such an important role, since it's the pathway that allows hearing loss to be caught right after birth, well before a delay in speech would otherwise raise concern.

The brain's capacity to learn speech and develop language naturally decreases after 5-6 years of age and is largely lost by 7-8 years of age. This makes early diagnosis and timely intervention absolutely critical. When a cochlear implant is done between 6 and 12 months of age, it provides near-natural hearing and allows language development to progress close to normal, provided proper habilitation protocols, like speech therapy and regular follow-up, are consistently followed afterward.

Research backs this up clearly: studies have shown better speech discrimination and stronger language development outcomes when the implant is done before 18 months of age, compared to children who receive it later. Essentially, the earlier the intervention, the more the brain can make use of the new auditory input during its most receptive window.
