Generally speaking, the age of cochlear implantation is about 1 year old, and patients are not eager to consider cochlear implant surgery for some reasons when wearing hearing aids. Cochlear implant surgery after 3 to 6 months is also expensive considering that hearing aids may also be more expensive. You can go to some large medical institutions (buy) or rent hearing aids, and wearing hearing aids in the interstitial period after the hearing diagnosis is clear and before the cochlear implant surgery is conducive to allowing children to establish the habit of listening. When he can hear some sounds, it is conducive to promoting the development of the child's speech center. It is helpful for the improvement of language rehabilitation ability after cochlear implantation in the future, so we still recommend early intervention to wear hearing aids as much as possible. If your child weighs more than 8 kg and is over half a year old, cochlear implants can be considered.
