My child has profound hearing loss.he is using hearing aids.Is there any way or method or medicine that helps us to go to normal hearing of my child?

Provided that your child's hearing loss is sensorineural and not conductive - and if it is profound it is certainly at least partially sensorineural - then no, there is no medical treatment or intervention that will correct his/her hearing loss. If your child is having a profound sensorineura hearing loss, please consider a cochlear implant to achieve the closest to normal hearing. My advice as a cochlear implant surgeon would be - dont delay, to avoid neural plasticity.
