“…formula) that reached 65% followed by FM width (63.5%) and FM length (63%), while in Abo El-Atta et al's study, the accuracy of FM width and FM length were 64.5% and 59.5% respectively. 22,23 However, Lopez et al values for discriminant function analysis were lower than the current study, prediction values were arranged from highest to the lowest as; Area2 (59.6%), Area1 (57.4%), FM length (51.1%) and the least was the FM width (44.7%). On the contrary, in Uthman et al study on the Iraqi population, the prediction value of FM Area was 69.3% which is higher than our study.…”

Objective: To evaluate the differences in the measurements of the Foramen magnum (FM) in relation to sex in an Egyptian population using cone beam computed tomography (CBCT).Material and Methods: One hundred and twenty retrospective CBCT scans of adult Egyptian individuals were included in this study (sixty males and sixty females). The maximum length (sagittal diameter) and the maximum width (transverse diameter) of the FM were measured on axial CBCT images, then the foramen magnum index (FMI) and foreman magnum area (using two different equations) were calculated. All the measurements were statistically analyzed.Results: It was found that all the FM measurements performed in this study were higher in males than that in females with statistical significance difference, except for the FMI which was higher in males, but the difference didn't reach the statistical significance level. Moreover, discriminant function analysis showed that FM length and FM area are the best sex discriminant measurements with overall accuracy of 65% and 64% respectively. Conclusion:FM measurements assessed on CBCT scans can be used as a reliable indicator of sexual dimorphism in the Egyptian population.

“…Although some recent studies by Darwish et and Slima & Abdou., 2020 performed FM analysis on the Egyptian population, these studies were done on CT images. 21,22,23,24 Therefore, as far we know that this current study was the first to perform FM measurements using CBCT on Egyptians.…”

“…However, there are no published studies testing the Walker method [ 17 ] on a living UK population. Additionally, a number of studies have demonstrated the utility of CT data and/or 3D modelling and its pertinence in assessing morphoscopic differences to assist with sex estimation, such as for use with the maxillary sinus [ 32 ], the foramen magnum [ 33 ], or the pelvis [ 6 , 34 ]. Considering cranial models specifically, 2D views and 3D volume reconstructions of the skull have been evaluated using general skull morphology [ 35 ] and using craniometrics [ 36 ].…”

Modern computed tomography (CT) databases are becoming an accepted resource for the practice and development of identification methods in forensic anthropology. However, the utility of 3D models created using free and open-source visualisation software such as 3D Slicer have not yet been thoroughly assessed for morphoscopic biological profiling methods where virtual methods of analysis are becoming more common. This paper presents a study that builds on the initial findings from Robles et al. (2020) to determine the feasibility of estimating sex on STL 3D cranial models produced from CT scans from a modern, living UK population (n = 80) using equation 2 from the Walker’s (2008) morphoscopic method. Kendall’s coefficients of concordance (KCC) indicated substantial agreement using cranial features scores in an inter-observer test and a video-inter-observer test. Fleiss’s Kappa scores showed moderate agreement (0.50) overall between inter-observer sex estimations, and for observer sex estimations in comparison to recorded sexes (0.56). It was found that novice users could virtually employ morphoscopic sex estimation methods effectively on STL 3D cranial models from modern individuals. This study also highlights the potential that digital databases of modern living populations can offer forensic anthropology.
