Hi Jane.. One of my support group members had a bilateral pallidotomy (actually two unilateral ones, 6 months apart). His speech was fine till he had the second surgery. He came out of the second surgery with no dyskenesia and no voice. It's been about 18 months since he lost his voice and we've all noticed it's suddenly back to about 3/4 of it's original volume. THAT came about from speech therapy I believe, rather than collagen injections... the latter of which he never looked into, according to him. As you know, I've had 3 pairs of collagen injections and have an appointment for the 4th pair in a few weeks.. My gut feeling - in no way verified by an MD who's performed the procedure for PD patients - is that collagen injections would NOT help in a post-pallidotomy situation. I could be wrong tho, and suggest an skilled MD's opinion would be the only way to really know if the injections would benefit your friend. Good luck to him....

He also can't swallow very well (makes throat noises at the meetings) Last meeting I gave them information about colligan treatments. Today his wife read it. She waited until I had cleared all my old mail out of my computer. Please help me. Do any of you think colligan would help his speech or swallowing problems?? Where have you heard that they are doing this? nearest to Oregon. Hope I spelled it right! jjjane http://www.parkinsonalliance.net/medical/palross/palross.htm
