本文使用 X 线头影测量对正常和近远中错的颅底结构及面型特征的关系加以分析。结果显示,颅底结构是相当恒定的,近远中错的存在和发展,并不经常伴有颅底结构的改变。另一方面,无论是正常还是近远中错,其颅底角和前颅底角与 SNA 角均存在负相关,所以,在进行临床 X 线头影测量分析时,必须考虑到 SNA 角与颅底结构之间存在形态因果关系,应结合颅底角和前颅底斜度的变异对 SNA 角测量值的意义作出正确判断。
In this paper, the use of X-cephalometry measurements of normal and near and far the wrong skull base structure and surface features of the relationship analysis. The results show that the skull base structure is fairly constant, near and far, the existence and development of the wrong foot, and not always associated with changes in the skull base structure. On the other hand, in both normal and near-midrange, there is a negative correlation between cranial base angle and anterior cranial base angle and SNA angle. Therefore, in clinical X-ray cephalometric analysis, the SNA angle and Skull base structure between the existence of morphological causal relationship should be based on the variation of skull base angle and anterior skull base slope Sense angle measurements to make the right judgments.
