Mapping the floor of the fourth ventricle to identify the motonuclei of cranial nerves VII-XII has been well-described. Though there are some reports of stimulating the pontomesencephalic surface to identify the extraocular motor nuclei, there is a debate as to its efficacy and utility in helping to identify safe entry zones for medullary incision in an intra-axial resection. We present two cases where we positively and negatively mapped the surface of the midbrain and rostral pons to assist in surgical decision-making. Both patients had gross total resections of cavernomas, and both awoke without any new onset extraocular motor deficits.
绘制第四脑室底部以识别颅神经VII - XII的运动核已经有了详尽的描述。虽然有一些关于刺激脑桥中脑表面以识别眼球外运动核的报道，但对于其在帮助确定轴内切除术髓质切开安全进入区域方面的有效性和实用性存在争议。我们展示了两例病例，在其中我们对中脑和脑桥前部表面进行了正向和负向绘图，以协助手术决策。两名患者的海绵状血管瘤均实现了全切除，且术后苏醒时均未出现任何新发的眼球外运动功能缺损。
