Abstract：
BACKGROUND: This study aimed to investigate the incidence, number, diameter, and relative location of the parietal foramen (PF) as well as communication of intracranial and extracranial orifices and their direction, and sagittal suture morphology and length.
METHODS: A total of 280 dry Chinese adult skull specimens from the Department of Anatomy, Southern Medical University, were observed and measured. The occurrence rate and quantity of the PF near the sagittal suture were recorded. The aperture of the PF, the vertical distance between PF and sagittal suture, and the linear distance between PF and lambda were measured using a Vernier calliper. The length of the sagittal suture was measured by a flexible ruler; the direction and communication of intracranial and extracranial orifices were detected using a probe.
RESULTS: The total incidence of the PF was 82.86%, slightly higher on the right side than on the left side. The single-foramen type was the most prevalent. The mean diameter of the PF on the left and right sides were 1.02 ± 0.72 mm and 1.07 ± 0.67 mm, respectively, and the diameter of the PF on the sagittal suture was 1.77 ± 0.44 mm. The mean vertical distance between the PF and the sagittal suture was 5.90 ± 2.78 mm and 5.85 ± 2.75 mm on the left and right sides, respectively. The shape of the sagittal suture in the PF area was primarily dentate shaped, with an average arc length of χ = 124.36 ± 7.76 mm, of which the majority were completely healed type. The intracranial and extracranial communication was 39.97%, and the majority of the PF were anteromedial direction.
CONCLUSIONS: The current study provided an anatomical basis for imaging diagnosis and neurosurgery by investigating the incidence, diameter, and relative location of the PF and intracranial and extracranial communication and direction.

摘要：
背景：本研究旨在调查发病率，number,直径,顶孔（PF）的相对位置以及颅内和颅外孔的连通及其方向，矢状缝线的形态和长度。
方法：从解剖学部门收集280个干燥的中国成人颅骨标本，南方医科大学,进行了观察和测量。记录矢状线附近PF的发生率和数量。PF的光圈，PF和矢状缝合线之间的垂直距离，使用游标卡尺测量PF和lambda之间的线性距离。矢状缝合线的长度由柔性标尺测量；使用探针检测颅内和颅外孔的方向和连通。
结果：PF的总发生率为82.86%，右侧比左侧略高。单孔型是最普遍的。左右两侧PF的平均直径分别为1.02±0.72mm和1.07±0.67mm,分别,矢状缝合线上PF的直径为1.77±0.44mm。PF与矢状缝线的平均垂直距离为5.90±2.78mm,左右两侧为5.85±2.75mm,分别。PF区域矢状缝线的形状主要为齿状，平均弧长为χ=124.36±7.76mm，其中大多数是完全治愈型。颅内和颅外通讯占39.97%,大部分PF是前内侧方向。
结论：当前的研究通过调查发病率，为影像学诊断和神经外科提供了解剖学基础，直径,以及PF的相对位置和颅内外通信和方向。
