Liz, I'm not familiar w/the procedure but I can tell you that I had brain surgery when I was 3 years old (back in the dark ages when they didn't know much). They shaved my head, drilled a hole in my skull and tried to "release the pressure", as they put it. My point is that I'm still here 57 years later, so I have a good feeling that you'll come through it just fine. Medicine has advanced since then, obviously, and you have the internet at your disposal to help w/your decision. I wish you only the best, a successful surgery and a speedy recovery.
