目的 探讨对顽固性颞叶癫痫的术前定位方法。方法 将 Ｍ Ｒ 对海马硬化的诊断作为一重要参考指标与 Ｅ Ｅ Ｇ 检查相结合，对１２ 例顽固性颞叶癫痫进行术前定位诊断，并与术中皮层 Ｅ Ｅ Ｇ 检查结果和术后随访结果比较。结果 Ｍ Ｒ 检查发现９ 例海马硬化，皮层 Ｅ Ｅ Ｇ 证实有同侧颞叶内侧放电，行选择性海马杏仁核切除术后病理证实海马硬化；未发现海马硬化改变３ 例行前颞叶切除术。随访０５ ～２ 年，疗效满意。结论 Ｅ Ｅ Ｇ 是诊断颞叶癫痫的最重要手段， Ｍ Ｒ 发现海马硬化对致痫灶定位有重要意义。
Objective To investigate the preoperative localization of refractory temporal lobe epilepsy. Methods M R diagnosis of hippocampus as an important reference index combined with E E G examination of 12 cases of intractable temporal lobe epilepsy diagnosis and preoperative positioning, and intraoperative E E G examination results and follow-up Results comparison. Results Nine cases of hippocampal sclerosis were found by MRI examination. The medial temporal lobe was confirmed by cortical E EG. The hippocampus was confirmed by histopathology after selective hippocampal resection of the hippocampus. No hippocampal sclerosis was found in 3 cases. . Follow-up 05 to 2 years, the effect is satisfactory. Conclusion E E G is the most important method to diagnose temporal lobe epilepsy. M R has found that hippocampal sclerosis is important for the localization of focal epilepsy.
