COLLIPAL, Erika et al. Morphometry Study of the Parietal Foramen. Int. J. Morphol. [online]. 2009, vol.27, n.2, pp.481-484. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022009000200028.

The bone parietal foramina usually minor, in these two numbers are located near the junction of the sagittal suture with lambdoidea. These foramina allow emissary veins draining into the superior longitudinal sinus in the occipital veins, and sometimes sends a small branch of the occipital artery. Anatomical studies in 39 cranium, well-preserved, adult, of the Anatomy Museum of the Universidad de La Frontera, Chile was realized. Recorded the following data: presence of the parietal foramen, the distance from the lambda and the parietal foramen parietal foramen to the sagittal suture and diameter of the parietal foramen. The 58.9% of the cranium presented each of the parietal bone foramen, 25.6% had a parietal foramen in a bone in the absence of contralateral and 15.3% had no parietal foramen. The average distance from lambda to parietal foramen was 33.25 mm, the distance from the sagittal suture to the parietal foramen averaged 6.29 mm, the average maximum diameter of the parietal foramen was 2.65 mm and a minimum of 0 , 37mm. These anatomical data provide new parietal foramen of the background for future studies.
