In this add on procedure, the provider has removed a portion of the skull, or he may create additional twist drill or burr holes in a patient’s skull. He then uses the stereotactic method, which makes use of a three dimensional coordinate system to locate small targets inside the brain, and places an additional neurostimulator electrode array on the targeted location in a subcortical site after placing an initial array during the same session. In this procedure, the provider does not obtain an intraoperative microelectrode recording. The provider performs this service to treat chronic difficult to control tremors, or dystonia, involuntary movements and muscle contractions, or Parkinson’s disease.
