目的:研究颅底骨性结构在头颅表面各个方位投影位置,为鼻咽癌放疗设野和颅底手术定位提供解剖学基础。方法;建立颅骨的三维空间坐标系统,在特制定颅器上以32个成年国人水平锯开的颅骨标本为测量对象。结果:测出了各相关结构的三维空间坐标值;制作出了与鼻咽癌放疗有关的部分结构在颅正面、两侧面和顶面的平面直角坐标（投影）图,使其位置和位置关系一目了然;同时还介绍了测算各结构点与颅表间深度和各结构点间连线与3个基准坐标面角度的方法。结论:各投影图可作为鼻咽癌放疗设野或病历记录的基本图形;可用数值来表示设野范围;使鼻咽癌的设野更加简便、灵活、准确、直观。
Objective: To study the projection position of cranial base bony structure in all directions of cranial surface, and to provide anatomical basis for radiotherapy and nasopharyngeal carcinoma radiotherapy and skull base operation positioning. Methods To establish the three-dimensional space coordinate system of skull and measure skull specimens of 32 adult people at special craniotomy. Results: The three-dimensional spatial coordinate values of each related structure were measured. The rectangular Cartesian coordinate (projection) diagram of the partial structure related to radiotherapy of nasopharyngeal carcinoma on the cranial surface, the two lateral surfaces and the top surface was made. The position and the positional relationship At a glance; at the same time also describes the calculation of each structure point and cranial surface depth and the connection between each structure point and the method of 3 reference coordinate angle. Conclusion: The projection images can be used as nascent nasopharyngeal radiotherapy or medical record of the basic graphics; numerical values can be used to indicate the scope of field; make nasopharyngeal cancer field more simple, flexible, accurate and intuitive.
