Morphometric evaluation of the foramen magnum for sex determination: A study from Saudi Arabia.
The present study provides a database of various morphometric dimensions of the foramen magnum region in the Saudi population. The objective of this study was to evaluate various measurements of the foramen magnum region for sex determination in the Saudi population by using computed tomography (CT) images. The various radiological measurements of the foramen magnum region were measured in a total of 200 adult subjects of Saudi origin including 100 males and 100 females. Sexual dimorphism was observed in five parameters related to the foramen magnum, namely length of the right occipital condyle (LROC), length of the left occipital condyle (LLOC), width of the foramen magnum (WFM), area of the foramen magnum (AFM) and length of the foramen magnum (LFM). The accuracy to discriminate sex ranged from 65.5% to 62.5% when LROC, LLOC, WFM, AFM, and LFM were considered as individual parameters. When multiple parameters were combined to discriminate sex, the highest accuracy of 71% was achieved.
