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.

Materials and 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 more on the right side than on the left side. The single foramen type was the most. 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.
