Sex determination is an initial and essential component of any medicolegal investigations. However, sometimes only cranial remains are available. The objective of this study was to determine sex using 12 craniofacial measurements in multidetector computed tomographic images of 150 Egyptian subjects (80 men and 70 women), with age ranging from 18 to 60 years. The results revealed a significant increase in the mean of all craniofacial measurements in men in comparison with women (P < 0.05). Bizygomatic breadth was the single most discriminant dimorphic parameter with an accuracy of 74%. Multiple discriminant functional analysis for sex prediction showed increased accuracy to 78.7% in all cases. Using multiple stepwise discriminants, functional analysis showed that the most predictive variables selected were maximal cranial breadth, minimal frontal breadth, bizygomatic breadth, orbital height, bimastoidale, and basion-prosthion length, which showed an accuracy of 80%. On the basis of this study, it is concluded that the cranial measurements obtained from multidetector computed tomographic images could be useful for forensic sex determination in Egyptians, especially in cases of skeletal remains.
