取成人颅骨标本３２个，采用解析几何原理，探讨建立颅骨某些结构的空间坐标和三维测量的方法。测出了颅底内面骨性解剖标志２７项，共５０个测点的三维坐标值，临床可根据坐标值测算有关结构在颅表的投影，以及推算各标志之间的位置关系。为临床检查、手术、穿剌、照射提供各种参考数据。 Thirty-two skull samples were taken from adult skulls. Using analytic geometry, the spatial coordinates and three-dimensional measurements of some skull structures were discussed. Twenty-seven anatomical landmarks of the skull base were measured, and the three-dimensional coordinates of 50 measuring points were measured clinically. Based on the coordinate values, the projection of the structure on the skull base was calculated and the positional relationship between the marks was calculated. For clinical examination, surgery, puncture, irradiation provide a variety of reference data.
