ABSTRACT
In the surgery of central area, identifying the motor cortex in front of central sulcus is imperative to prevent loss of motor function. Twenty five patients with tumors or intractable epilepsy near the central sulcus were operated on at the Department of Neurosurgery of Chonbuk National University Hospital, from September. 1991 to December 1993. An estimated localization of lesions was performed with Callosal Grid System, which is a methodolgy made available by the development of high quality of magnetic resonance imaging, digital subtraction angiography and high resolution computerized tomography. This system allowed us to be oriented to the motor cortex as well as permitted assessment of the extent of resection. This was further delineated by direct electrical stimulation, which confirmed the functional motor cortex and made it possible to maximized the tumor resection near and in the motor cortex. The combination of direct cortical stimulation(functional mapping) and the use of the Callosal Grid System(anatomical mapping) allowed us to identify the spatial relationship between them as well as to maximize the tumor resection in most cases without injury to the central area, so that the better outcome is guaranted.
