The contralateral interhemispheric approach has several advantages for approaching parasagittal lesions, including lesions involving or approaching the medial precentral gyrus. Supplementing the interhemispheric approach with asleep motor mapping is useful for confirming the location of the corticospinal tracts from the contralateral transfalcine corridor and identifying subcortical motor fibers at the deep aspect of the resection cavity. The authors describe the contralateral interhemispheric, transfalcine approach with asleep motor mapping to resect a parasagittal metastatic lesion involving the medial precentral gyrus.

对矢状旁病变，包括累及或靠近正中额回的病变，双侧额下入路具有若干优势。将术中运动皮质定位技术与双侧额下入路联合应用，有助于确认来自对侧经颅中窝入路的皮质脊髓束位置，并识别切除腔深部的皮质下运动纤维。作者描述了在术中运动皮质定位技术辅助下采用双侧额下入路、经颅中窝入路切除累及正中额回的矢状旁转移病灶。视频可见：https://youtu.be/L-fJ6m5kOWs。
