本文对0 ~ 18岁男220例、女177例的头影测量片进行了颅底和穹窿的长度和角度的测量。这些孩子是Fels纵向生长研究的参与者。本研究是基于混合纵向数据来自1861 X光片的男孩和1401 X光片的女孩。在本研究中，颅底的解剖部分指定如下：颅底（鼻根-基底）、前颅底（鼻根-鞍）、额筛段（鼻根-蝶筛）、前蝶骨段（蝶筛）、后颅底（鞍-基底）、蝶骨段（鞍-枕）和枕底段（蝶枕-基底）。颅内点用于颅骨区域的顶点和前后界限。此外，还测量了三个角度（鼻根-鞍-基底;鞍-鼻根-点A;鼻根-点B）。鞍后鼻棘）。描述了每个维度的平均值随年龄的变化。将样本分为3个年龄组（0-3岁、4-6岁、7-18岁）后，通过线性回归分析每个变量来检验观察到的年龄变化的统计学显著性。与报道的研究结果相反，男女的蝶骨底段和枕底段都随着年龄的增长而稳定增长。鞍点A角在男孩10岁和女孩9岁之前会减小;在年龄较大时，男女都有随年龄增加的趋势。
Lengths and angles within the cranial base and vault were measured in cephalometric radiographs of 220 boys and 177 girls ranging in age from 0 to 18 years. These children were participants in The Fels Longitudinal Growth Study. The present study is based on mixed longitudinal data derived from 1861 radiographs for boys and 1401 radiographs for girls. In this study, the anatomical parts of the cranial base are designated as follows: cranial base (nasion-basion), anterior cranial base (nasion-sella), fronto-ethmoidal segment (nasion-sphenoethmoidale), presphenoid segment (sphenoethmoidalesella), posterior cranial base (sella-basion), basisphenoid segment (sella-sphenoccipital), and basioccipital segment (sphenoccipital-basion). Endocranial points are used in the calvarial area for the vertex and anterior and posterior limits. Moreover, three angles are measured (nasion-sella-basion; sella-nasion-point A; nasion..sella-posterior nasal spine). Changes with age in the mean values for each dimension are described. The statistical significance of the observed age changes was tested by linear regression analysis for each variable after dividing the samples into three age groups (0-3, 4-6, 7-18 years). Contrary to reported findings, both basisphenoid and basioccipital segments increase steadily with age in each sex. The angle sella-nasion-point A decreases until the age of 10 years in boys and 9 years in girls; at older ages there is a tendency to increase with age in each sex.
