“…22 Differences are observed when calculating the area of the foramen magnum by Radinsky's method, Teixeira's method, and while using computer software. 22,23 Similar to the previous studies, the present study also found that the mean values of various metric measurements were greater in males than in females. Sexual dimorphism could be established from the foramen magnum which was 71% by multivariate analysis and 70.5% for selected variables who showed higher classification accuracy in step wise method in the present study.…”

Background Estimation of sex of the skeletal remains plays a vital part in the identification of an individual. This study is focused on the morphometric measurements of the foramen magnum region and examining the accuracy of sexual dimorphism in the Nepalese population. Methods Measurements were obtained from 3D computed tomography (CT) scan of 261 Nepalese adult cranial bases with known age and sex. Length and breadth of the foramen magnum, length and breadth of right and left occipital condyles and maximum and minimum intercondylar distance were measured on the base of the skull CT images. Results The mean values for all parameters were higher in males than females except for the maximum intercondylar distance. Sex prediction done with discriminant function analysis could classify the skull with an overall accuracy of 70.5%–71%. Conclusions It can be concluded from the results that the morphometric study of the foramen magnum is less reliable for sex estimation in the Nepalese population.

“…The shape of the foramen magnum is not always round and there are various shapes like oval, tetragonal, pentagonal, hexagonal, egg, and irregular 22 . Differences are observed when calculating the area of the foramen magnum by Radinsky's method, Teixeira's method, and while using computer software 22,23 …”
