Effects of bilateral deep brain stimulation of the subthalamic nucleus on olfactory function in Parkinson's disease patients.

abstract：OBJECTIVE:We compared bilateral globus pallidus internus (GPi) deep brain stimulation (DBS) with bilateral GPi DBS plus ventralis oralis (Vo) thalamotomy to analyze the effect of the combined Vo thalamotomy. METHODS:Between March 2003 and December 2008, 10 patients underwent DBS and/or Vo thalamotomy for treatment of ...
