The localization of a seizure focus for resective surgery often requires invasive monitoring for precise localization of the target as well as structures to avoid. We report on the use of intra-operative surgical navigation to precisely localize and co-register subdural electrodes to regions of know radiographic pathology. Additionally, the navigation system was used to develop intra-operative electrode maps. These maps were subsequently used in the sub-acute recording phase to assign electrographic pathology and function (e.g. speech) to a specific cortical surface anatomy. This permitted for more precise planning of surgery and better assessment of potential risk, based on functional as well as anatomical criterion.
对于切除性手术而言，癫痫病灶的定位通常需要进行侵入性监测，以精确确定靶点位置以及需要避开的结构。我们报告了术中手术导航的应用，该导航用于将硬膜下电极精确地定位并与已知影像学病变区域进行配准。此外，导航系统还用于绘制术中电极图谱。这些图谱随后在亚急性记录阶段用于将脑电图病变及功能（如言语功能）与特定的皮质表面解剖结构相关联。基于功能及解剖学标准，这使得手术规划更加精确，并能更好地评估潜在风险。
