Aim of Stereotactic Surgery
The aim of the Stereotactic Surgical Technique is to allow physiological exploration or destruction of deep cerebral, spinal cord, or body structures with a minimum of disturbance to surrounding regions. These structures are invisible from the surface, but their location can be determined by a knowledge of their coordinates in space relative to known anatomical and topographical landmarks. The use of the stereotactic technique in neurosurgery, radiosurgery, and/or stererotactic radiation therapy avoids extensive open operative approaches. The technique generally involves the placement of treatment modalities into strategic "target areas." The target area of interest may be a specific functional anatomical site or a morphological lesion or abnormality.
