Diane... I had a very successful unilateral (one side only) pallidotomy performed at Loma Linda University Hospital (in Southern California, USA) Oct. 24, 1994. And yes.... ya DO need to continue taking Sinemet after the surgery, however, many persons can get by with a much lesser dose of the drug. A coupla words of caution: Pallidotomy is NOT a cure and each individual Parkie responds to the surgery in their own unique way. But overall, I believe most folks having this surgery benefit from it to some degree, depending upon the type of PD they have, their age and general physical condition (i.e., a 60 year old would prolly do better than an 85 year old) ALSO..... it is the utmost importance one uses a neurosurgeon who has performed LOTS of successful pallidotomies and who can refer you to PD patients whom he has operated on in the past for you to contact for references. Ya sure don't want a neuro who's LEARNING how to do this procedure messing 'round in YOUR brain! YIKES!!!

Do you still rely on Sinnemet after the operation Diane
