“…In some studies, it was noted that this foramen may be 3 or more in number [4,8,9,17,26,30]. Liu et al [12] stated that all the PFs they observed were singles. Murlimanju et al [17] 4).…”

“…The prevalence of PF varies between 50% (USA) and 86% (Thailand) in different ethnic groups [14,30]. The frequency of bilateral PF ranged from 24.2% (European) to 74.65% (Turkey), while the frequency of unilateral PF ranged from 20.2% (African) to 66.07 (Chinese) right side and 63.21 (Chinese) left side [8, 12,27]. Similarly, the frequency of PF on the SS ranged from 0.7% (Japan) to 33.7% (Turkey) [8,15].…”

“…The prevalence and location of PF have been reported to vary among different ethnic groups [4,11,12,27]. Smarhalov et al [22] emphasized that anatomical variations of PF are not rare and reported that it is important to know in detail the anatomical variations in different population groups to facilitate invasive procedures.…”

Purpose: Very few studies exist on the parietal foramen (PF) in Turkish skulls. We aimed to investigate the PF in Turkish population and to emphasize its possible clinical implications. Methods: A total of 174 (81 right and 93 left) Turkish dry adult human parietal bones were examined carefully. The presence and number of PF were recorded as well as shape and direction. The diameter of PF (DPF) was determined with various diameters of needles. The vertical distance of PF to sagittal suture (DSS) and to horizontal line that passes over the lambda (DPL) was calculated. The length of the sagittal suture (LSS) and the LSS/DPL ratio were also determined. All distances were measured with a digital caliper. Results: The prevalence of PF was 64.3% (112 parietal bones). A total of 118 PFs were detected, 52 on the right side, 58 on the left side, and 8 on the sagittal suture. Single (90.7%), double (6.8%), and triple (2.5%) PF existed. Circular (94.1%) and oval (5.9%) shaped PF were observed. The majority of the PF were posteroanterior direction. The most common diameter of PF was 0.8 ≤ DPF < 1.25. The mean DSS, LSS, and DPL were 6.81±3.40 mm, 108.94±6.91 mm, and 33.81±12.43 mm, respectively. In addition, the LSS/DPL ratio was approximately 3/1. Conclusion: This is the first study to examine the direction of PF in detail in Turkish population. The anatomical findings obtained in this study may play a significant role in increasing the success rate of invasive procedures involving PF.

The aim: Estimate the prevalence of the parietal foramen in the adult human skulls of Ukrainian origin, and study its morphology and relationships to main anatomical landmarks of the skull. Materials and methods: A cross-sectional observational study of PF was conducted with 42 random cadaveric adult human skull roofs (calvaria) collected from the laboratory and museum of Human Anatomy Department, Kharkiv National Medical University, Ukraine. The patency and the length of the PF canal were determined, and PF external/internal diameters and the distance to the calvarial landmarks from PF were measured using the caliper. Mean and standard deviation were calculated to compare with the existing data. Results: In the present study 85.7% (n = 36) of the calvaria had the PF, 54.8% (n = 23) had bilateral location of PF, 30.9% (n = 13) had unilateral presence of PF (right side: 23.8%, n=10 and left side: 7.1%, n=3), and 14.3 % (n = 6) demonstrated bilateral absence of PF. Conclusions: An anatomical variation in parietal foramen is not uncommon, and the differences can be based on multiple factors like geography and race. It is important to have detailed information on anatomical variations in different population groups to facilitate surgical and radiological interventions.
