Hello,Sue I had a pallidotomy in 1996. It was done on the right side oif my brain so its effects would be felt on my left side. I would call it a success. It relieved much of the dystonic pain i was having on that side. I have bee n taking tasmar about 6 weeks-I think it is helping. It is desoigned to enhance or make the levadopa in sinemet more effective. Hope you have success--if i can answer any specific questions about the pallidotomy, just ask------pete
