囟门乃婴儿头颅解剖构造上的一大特征,有前囟和后囟之分。前囟呈现菱形四边形,为顶骨和额骨之间的空隙,后囟呈现三角形,为顶骨和枕骨之间的空隙。新生儿前囟面积约2.5×2.5厘米(对边中点边线),6个月之后,随着颅骨缝逐渐骨化面积变小,到1周岁、最迟不超过18个月闭合,为骨质所取代。后囟在出生时已接近闭合,或仅可容纳指
The fontanelle is a major feature of infant head anatomy, with anterior and posterior fontanel. The anterior fontanelle presents a rhombic quadrilateral, the gap between the parietal and frontal bones, the posterior fontanelle presenting the triangle, the gap between the parietal and occipital bones.
