目的：颅底在正常和病理面部模式的贡献中的重要性尚不确定。本研究的目的是探索和比较面部和侧颅骨（颅前窝和中颅窝）之间的形态协变模式以及面部和中线颅底之间的协变模式。 设计：我们采用 2D 几何形态测量学和偏最小二乘分析来量化和比较来自日本（N = 45）和欧洲的 143 名受试者的侧位 X 线照片中的颅骨和面部结构之间的主要变异模式之间的相关系数（N = 65）和非洲（N = 34）。结果：在这两次比较中，基本颅骨模式与长面部和短面部形态共同变化。研究结果表明，中线颅底与常见面部模式没有显着相关性（r = 0.37，P = 0.09）。相反，与中线颅底相比，外侧基骨与面部变异的相关性显着（P = 0.000），并且显着更高（r = 0.6）。 结论：外侧基骨对影响面部变异的形态发生相关性可能比之前认为的更高。这种影响对于骨性 II 类或 III 类错牙合的产生可能具有临床重要性。进一步的研究应扩展个体发生和临床 3D 数据的几何形态测量分析，以加深对这些复杂发育关系的理解。 (c) 2006 Elsevier Ltd. 保留权利。
Objectives: The significance of the cranial base in the contribution of normal and pathologic facial patterns is uncertain. The aim of this study was to explore and compare patterns of morphological covariation between the face and the lateral basicranium (anterior and middle cranial fossae) with covariation patterns between the face and the midline cranial base.Design: We employed 2D geometric morphometrics and partial least squares analysis to quantify and compare correlation coefficient between principal variation patterns between basicranial and facial structures in lateral radiographs from 143 humans from Japan (N = 45), Europe (N = 65) and Africa (N = 34).Results: In both comparisons basicranial patterns co-varied with dolichofacial and brachyfacial morphologies. The findings showed that the midline cranial base is not significantly correlated of common facial patterns (r = 0.37, P = 0.09). Instead, the lateral basicranium is significantly (P = 0.000), and significantly higher (r = 0.6) correlated with facial variation than is the midline cranial base.Conclusions: The lateral basicranium may be of higher morphogenetic relevance for influencing facial variation than previously thought. This influence may be of clinical importance for the generation of skeletal class II or class III malocclusions. Further research should expand on geometric morphometric analysis of ontogenetic and clinical 3D data in order to advance in the understanding of these complex developmental relationships.
