How much does an eardrum transplant cost to restore hearing?

Question

Update:

Me neither, Zirp but I know is possible a cornea transplant to restore sight

Answer 1

I didn't know that that was possible. A far as I can tell/google, they are pretty rare. In most cases they try to restore the eardrum by creating it from your own body-tissue

Answer 2

Nothing if you live in any First World Country other than the United States.
