George - My husband, Dick, had two pallidal stimulations (same procedure as pallidotomy except they leave the electrodes in and don't create a lesion) in '95 and '96. He also had a problem with his voice following the surgeries. The first surgery was somewhat complicated, and he ended up being awake on the table for 9 hours. Following that, he couldn't make any sound at all for three days. (Moved his lips but no sound came out). Then his voice was weak and raspy, and likely to quit entirely in mid-sentence. It improved somewhat as time went on, although it seems to me that it continues to be more undependable than before the surgeries. He has had speech therapy, which has helped considerably. He also experienced "mushy brain" - had some memory lapses that were pretty scary to me - that lasted about six months, I think. He also was totally unsafe behind the wheel of a car for some time afterward - even up to six months. George, do you still drive? Please remember what I said about Dick and be careful. The doctors didn't warn him about driving except for the first 30 days after surgery. We hope your second thalamotomy turns out to be successful. Dick's second surgery wasn't as successful as the first, although we know others with two pallidal stimulations who found the second operation was more successful for them. I think it has to almost entirely with the placement of the electrode or the lesion - but I imagine the doctors would tell us it's much more complicated than that. Good luck to you.
