Neurosurgical Center of Chinese PLA Department of Neurosurgery, Navy General Hospital Beijing (100037) CHINA Combined Operations With MST in the Treatment of Intractable Epilepsy Background In recent years, operations have been the major procedure for treatment of medically intractable epilepsy. Removal of epileptogenic lesions was believed to be a best approach for seizure control. Background But when functional area or the extensive of hemisphere were involved by the epileptogenic focus, the outcome will be affected by the residue lesion, which lies unresectable cortex, such as precentral gyrus, postcentral gyrus, Brocas area, Werniches area, etc. Background Combined operations with MST can reduce the occurrence of synchronized cell discharge and may not impair the major functional capacity of cortex by preserving vertically oriented fibers. Material and Method Clinical material The combined operations with MST have been applied in 130 patients who suffered from medically intractable epilepsy from January 1996 to January 2001. Male 98 and female 32 Age: 10-55 (mean 30.7) years. Initial attack: 2-40 (mean 17.2) years. Duration of illness: 3-48 (mean 9) years.
