目的　探讨皮层脑电图监测下切除或热灼伴有癫痫症状的脑肿瘤的手术效果。方法　 16例伴有癫痫症状的脑肿瘤患者 ,术中通过皮层脑电图确定癫痫灶 ,切除肿瘤后 ,切除或热灼可疑癫痫灶。术后随访患者的癫痫发作情况。结果　 16例患者切除肿瘤前均可通过皮层脑电图探及痫波 ,肿瘤及痫灶完全切除后 ,痫波消失者 15例 ,1例功能区患者虽多次皮层热灼 ,仍可见偶发棘波。术后 15例未再有癫痫发作 ,1例有部分性发作 ,用抗癫痫药可控制。结论　术中皮层脑电图监测切除或热灼癫痫灶是一种有效控制肿瘤切除术后癫痫发作的方法 Objective To investigate the surgical effects of cystectomy or cauterization of brain tumors with epilepsy under cortical EEG monitoring. Methods Sixteen patients with brain tumor with epilepsy were enrolled. Intraoperative epileptic foci were identified by cortical EEG. After excision of tumor, excision or thermal ablation of suspected epileptic foci were performed. Postoperative follow-up of patients with seizures. Results 16 cases of patients before removal of the tumor can be detected by cortical EEG and epileptic waves, tumor and complete removal of the epileptic foci, the disappearance of 15 cases of epileptic wave, a case of functional area despite repeated cortical burning still sporadic spines can be seen wave. There were no further seizures in 15 cases and partial seizures in one case, which could be controlled by antiepileptic drugs. Conclusion Intraoperative cortical EEG monitoring resection or epileptogenic foci is an effective method to control the seizure after tumor resection
