目的：探讨立体定向手术治疗颞叶癫痫的手术前后脑电图变化与疗效关系。方法：术前及术后１周进行脑电图检查，并比较其变化。根据随访的疗效结果，判断其与脑电图变化的关系。结果：双侧杏仁核及一侧Ｆｏｒｅｌ－Ｈ区联合损毁效果最好，术后脑电图局部棘波变化率较大（Ｐ＜００５）。结论：术后脑电图也是术后疗效评价重要指标 Objective: To investigate the relationship between EEG changes and curative effect before and after stereotactic surgery for temporal lobe epilepsy. Methods: Electroencephalography was performed preoperatively and 1 week after surgery, and their changes were compared. According to follow-up of the efficacy of the results to determine the relationship between EEG changes. Results: The combination of bilateral amygdala and Forel-H area on one side had the best destructive effect, and the change rate of EEG local spikes was higher after operation (P <005). Conclusion: Postoperative EEG is also an important indicator of postoperative efficacy evaluation
