Use of the callosal grid system for the preoperative identification of the central sulcus.
The callosal grid system based on modern imaging techniques facilitates the identification of the central sulcus by its relationship to the midcallosal plane. Imaging with or without the stereotactic frame allows precise localization of various anatomic sites, which can be compartmentalized within subdivisions of the grid system. The information gained permits accurate preoperative planning and intraoperative recognition of the central sulcus and adjacent neurovascular structures.
