Intraoperative neuromonitoring techniques can be used to evaluate neural functions during surgical procedures. For removal of tumors in the skull base region, we perform them for both structural mapping of the compressed cranial nerves and continuous monitoring of their preservation. The goal is to eliminate the critical irreversible damage to the neurological structures and prevent postoperative neurologic deficits. Recording techniques have been developed and neuromonitoring equipment used in the operation room with the intravenous anesthesia technique. For skull base surgery, in particular, the neuromonitoring contains motor evoked potential(MEP), brainstem auditory evoked potential(BAEP), visual evoked potential(VEP), and others. We believe that the appropriate recording and interpretation of these data can greatly improve the surgical outcomes of tumor removal and prevent postoperative neurologic deficits.
术中神经监测技术可用于在外科手术过程中评估神经功能。对于颅底区域肿瘤的切除，我们采用这些技术来对受压颅神经进行结构定位并持续监测其保留情况。目标是消除对神经结构的严重不可逆损伤并预防术后神经功能缺损。记录技术已经得到发展，并且在手术室中结合静脉麻醉技术使用神经监测设备。特别是对于颅底手术，神经监测包括运动诱发电位（MEP）、脑干听觉诱发电位（BAEP）、视觉诱发电位（VEP）等。我们相信对这些数据进行恰当的记录和解读能够极大地改善肿瘤切除的手术效果并预防术后神经功能缺损。
