!. How many of you who have had Pallidotomies wish you had done it sooner? 2. How long did you wait before deciding to do it? 3. What kind of pre-op studies need to be done and how long do they take. Thanks to any of you who will take time to answer questions that I know have been posted before. I wasn't thinking in terms of ever having one at the time, so I did n't pay allot of attention. So please humor me and help me out if you would. Marty Rose [log in to unmask]
