颅脑病灶术前进行头皮定位 (尤其在小切口微侵袭手术 )有助于手术切口的确定 ,以求准确、快捷。但仅根据ＣＴ、ＭＲＩ影像资料进行头皮精确定位并不易。我们介绍两种术前ＣＴ扫描时使用激光点进行头皮定位的简易装置及使用方法。装置一 (图 1) :使用一长方形木条或泡沫条 ,长度 Preoperative craniofacial scalp localization (especially in small incision microinvasive surgery) to help determine the surgical incision, in order to accurately and quickly. However, accurate scalp positioning based on CT and MRI images is not easy. We describe two easy-to-use devices for laser scalp positioning using two preoperative CT scans and how to use them. Device one (Figure 1): Use a rectangular strip of wood or foam, length
