The purpose of this study was, firstly, to characterize the mastoid process in terms of its size, its surface area, its flare and its medial convergence angle on a sample of Jordanian subjects; and secondly, to assess the validity of the mastoid process in determining the gender of the study subjects. The sample of the study comprised 192 3D skull images with known sex, 96 each male and female, those were obtained by rendering DICOM images from cone-beam computerized tomography of the subjects. Radiographic measurements, using customized software, accurately characterized the subjects’ mastoids. Discriminant function analysis revealed that mastoid process correctly classified the sex in 90.6 percent of the subjects and the intermastoidale distance was found to be the best determinant for sex. A discriminant function equation specific for young and middle age Jordanians has been derived from the mastoid variables.
