Abstract: Objective:To discuss the application of awaking anesthesia and neurophysiological techniques in epilepsy surgery involved in the language areas. Methods: The relationship between Epileptogenic lesions and (or) epileptogenic focus and the language areas were confirmed by preoperative assessments in 9 patients. Electrocardiography recordings were adopted to confirm the epileptiform discharge area, and then cortical electrical stimulation was performed to locate the language areas. According to the relationship between the language areas and epileptogenic lesions and (or) eileptogenic focus, we choose the appropriate surgical approach to protect the language areas and remove epileptogenic lesions and (or) eileptogenic focus. BCFC or MST has been used to deal with epileptiform discharge area. We evaluated language function and control of epilepsy postoperation.Results:There were 4 patients with language dysfunction after operations，and 3 of which was reversible within two weeks, but 1 patient was moderate motor aphasia. Patients were in a good control of epilepsy.7 patients were EngelⅠand 2 were EngelⅡ.Conclusion:Awaking anesthesia and intraoperative neurophysiological techniques were reliable and precise in epilepsy surgery involved in the language areas, which allow a maximum resection of the epileptogenic lesions and (or) epileptogenic focus and protection of language areas, which improve the life quality of patients.
