Stereotactic Pallidotomy

Visit our Specialty Centerr

A stereotactic pallidotomy is an ablative procedure that treats movement symptoms of Parkinson’s disease by creating a small, precisely placed lesion in the globus pallidus (part of the basal ganglia, the brain region that controls movement). It has largely been replaced by deep brain stimulation (DBS), but may still be recommended in selected cases where DBS is not an option.
