Hi Susan,
Another Susan chiming in. I had Gamma Knife on my 2 cm AN last April 18th. I don't have much hearing in my left ear....I cannot hear anything on the phone, for example, and I have zero word recognition...I was never given a percentage of hearing loss, but as of last summer I was in the "severe" hearing loss catagory, rather than the "profound" hearing loss that my audiologist said many AN'ers were in. It wouldn't surprise me, however if I tested in that catagory now. My doctor is a neurosurgeon, and also does radiosurgery, so he advised me to go that route. Sad to say that some neurosurgeons will pooh-pooh radiosurgery, because frankly they lose income by refering you to somebody else. It's a nice idea, if you can, to talk to experts in both fields.
I wish you all the best from one Susan to another...
