My step-daughter went to an elementary school where they had a program for deaf kids (each elementary school here has at least one specialized program for disabled kids, the cerebral palsy school, the blind school, the deaf school, etc.)
You would see a lot of the kids from the cancer hospital because cisplatin had killed off their cochleae. Maybe this could be a way to counter the ototoxic effects of chemotherapy drugs.
I pray that it is so.....................
