摘要
目的 测量鼻根部到颅前窝、额窦的最短距离。为安全放置克氏针,确定外部参考点建立解部学指导。方法 选择20例正中矢状切开的成人尸头标本,使用游标卡尺,测量(1)鼻根点到前颅窝的最短距离;(2)额窦最低点到通过鼻根点水平线的最短距离。结果 从鼻根点到前颅窝的平均距离为15.6mm,从鼻根点到额窦的平均距离为4.5mm。结论 克氏针从前上向后下进入相对前颅窝和额窦为安全路径。
Objective The purpose of this study was to measure the shortest distance from the nasion to the anterior cranial foss and from the nasion to the frontal sinus. These measurement were used to establish anatomic guidelines govering safe placement of external reference point pins. Methods 20 heads were selected in the midsagittal plane for gross study. Using vemier callipers, two specific measures were obtained: (1)distance from deepest depression of nasion to the most anterior and inferior projection of the anterior cranial fossa, and (2) distance from nasion to the most inferion aspect of the front sinus. Resuts The average distance from nasion to anterior cranial fossa was 15. 6mm. The average distance from nasion to the frontal sinus was 4. 5mm. Conclusions Directing the pin from anterior superior to posterior in ferior provide safty for both the anterior cranial fossa and the frontal sinus.
