Choi, Chang Rak; Ahn, Myung Soo

Abstract

Our experienced is based on a series of 5 cases of dystonia who underwent stereotaxic thalamotomy. The immediate good results have been obtained by thalamotomy. We have been able to estimate secondary deterioration on long term results in patients examined 2-5 years postoperatively. Some deterioration is noted patients operated on for athetosis over the age of 20. A pallido-subthalamic lesion is efficient at the beginning of the disease course since it improves motor performance and thereby helps possiblities of intellectual acquirement. Bilateral lesions have done after improved. I.Q. Effects of this treatment specially on spasticity must be discussed among other types of surgery.
