Aim: Few studies have analyzed the possible association between parietal foramen (PF), sagittal suture (SS), and lambdoid suture (LS). The relationship between the SS, LS, and PF might play a role in identifying various ethnicities or essential in surgery. The study examined the location, type, incidence, diameter of PF, and the relationship between SS and LS in Turkish adult dry skulls. Methods: A cross-sectional morphological and morphometrical study of PF was conducted with one hundred and sixty-six Turkish adult dry skulls in 2018-2020. The numbers, frequency, diameters, and types of PF were measured by a digital caliper. For morphometric analyses, the shortest distances between PF-SS, median PF (MPF), Lamba, and PF-LS were measured. Results: The incidence of PF was 74.6% (right) and 74.7% (left). The incidence of PF was 63.3 in males, it was 36.7 in females. Bilateral PF was found in 74.65%, and unilateral PF was present in 55.75% of Turkish dry skulls. The MPF was found on the SS in 33.7% of the skull. The PF-LS was 39.88±1.99 mm (2.91-104.11 mm) on the left side and 40.69±1.67 mm (6.03-101.24 mm) on the right side. The PF-SS was 12.87±1.25 mm (0.26-85.03 mm) on the left side and it was 11.95±1.21 mm (0.40-83.36 mm) on the right side (p=0.01). Conclusion: The significant differences in the PF-SS on the left side according to sex should be considered in surgery. Other findings of the study are the presence of more than one PF and its asymmetric distribution in the skull. This might be due to the delayed ossification process or differences in ethnicity.
