摘要 目的探讨发作间期脑电图在难治性内侧颞叶癫(medial temporal lobe epilepsy,MTLE)术前评估以及预后判断中的价值。方法对28例难治性内侧颞叶癫手术患者术前评估资料及术后随访情况进行回顾分析。统计前颞区发作间期放电(in-terictal epileptic discharges,IEDs)棘波次数,区分单侧放电(≥90%的IEDs局限于一侧)与双侧放电、单侧优势(双侧独立IEDs在每侧均<90%,且一侧独立IEDs≥75%),并将其与发作期脑电图,MRI结构异常以及术后结果比较。结果发作间期放电(IEDs)明确单侧者比有双侧放电表现为IEDs单侧优势者显示更好的预后;对于有海马硬化(hippocampal sclerosis,HS)的患者,与IEDs一致均有满意的手术效果。结论术前发作间期脑电图有助于MTLE的术前定位以及预后评价。
