Long term results of stereotaxic surgery for infantile dystonia and dyskinesia.
Our experience is based on a series of 25 patients suffering from infantile dyskinesias and dystonias who underwent stereotaxic surgery of basal ganglia. We first note the immediate good results (77%) obtained by thalamo-sub-thalamotomy. Concerning dyskinesia this type of surgery enjoys in an opinion a place of choice. Secondly we have been able to estimate secondary deterioration on long term results in patients examined 2 to 15 years post-operatively. In contrast to various results reported in the literature good long term results are not superior to 50%. Some deterioration is noted in patients operated on for choreo-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 possibilities of intellectual acquirement. Bilateral lesions have after improved I.Q. Effects of this treatment specially on spasticity must be discussed among other types of surgery.
