The anterior cranial base has long been considered a stable reference structure for superimposing radiographs. However, some studies have questioned its stability. Therefore, the purposes of this systematic review were to give an overview of the studies evaluating growth and development of the anterior cranial base, assess their methodologic quality, and evaluate their validity and accuracy.
Medline, Embase, and Google Scholar were searched without limitations up to June 2013. Additionally, the bibliographies of the finally selected articles were hand searched to identify any relevant publications that were not identified before. The lowest levels of evidence accepted for inclusion were cohort and cross-sectional studies.
A total of 11 articles met all inclusion criteria. They were published between 1955 and 2009. The sample sizes of these studies ranged from 28 to 464 subjects. Their methodologic quality ranged from moderate to low.
Sella turcica remodels backward and downward, and nasion moves forward because of the increase in size of the frontal sinus. These events lead to a continuous increase in the length of the cranial base until adulthood. The presphenoid and cribriform plate regions can be considered stable after age 7, making them the best cranial-base superimposition areas.
长期以来，前颅底一直被视为用于头颅侧位片重叠分析的稳定参考结构。然而，一些研究对其稳定性提出了质疑。因此，本系统综述的目的是概述评估前颅底生长发育的研究，评估其方法学质量，并评价其有效性和准确性。
检索了截至2013年6月的Medline、Embase和谷歌学术，无检索限制。此外，还手工检索了最终选定文章的参考文献，以识别之前未发现的任何相关出版物。纳入的最低证据水平为队列研究和横断面研究。
共有11篇文章符合所有纳入标准。它们发表于1955年至2009年之间。这些研究的样本量从28例到464例不等。其方法学质量从中等到低。
蝶鞍向后下方重塑，鼻根点因额窦增大而向前移动。这些变化导致颅底长度持续增加直至成年。蝶骨体前部和筛板区域在7岁后可被视为稳定区域，使其成为最佳的颅底重叠区域。
