Electrodes placed stereotactically in mesial temporal lobe structures may be useful for determining laterality, and extent of the epileptogenic zone in temporal lobe epilepsy. We present and compare our experience with the use of two stereotactic arcs, the Brown-Roberts-Wells (BRW) and Cosman-Roberts-Wells (CRW) for magnetic resonance imaging guided placement of multicontact electrodes in the amygdala, anterior and posterior hippocampus. Out of 101 electrodes, 28 were placed in 6 and 17 patients using the BRW and CRW arcs, respectively. The target-centered design of the CRW arc eliminated the need for trajectory calculations, used uniform 'depth' measurements, and allowed greater operative flexibility and a shortened operating time. The use of depth electrode recording allowed 14 of the 23 patients to be selected for temporal lobectomy.
立体定向放置在颞叶内侧结构中的电极，可能有助于确定颞叶癫痫中癫痫灶的偏侧性和范围。我们展示并比较了使用两种立体定向弧，即布朗 - 罗伯茨 - 韦尔斯（BRW）和科斯曼 - 罗伯茨 - 韦尔斯（CRW），在磁共振成像引导下将多触点电极放置在杏仁核、海马前和海马后的经验。在101个电极中，分别使用BRW弧和CRW弧在6例和17例患者中放置了28个电极。CRW弧的以靶点为中心的设计消除了轨迹计算的需要，采用统一的“深度”测量，并允许更大的操作灵活性和缩短手术时间。深度电极记录的使用使得23例患者中的14例被选作颞叶切除术。
