Craniometric analysis applies a combination of both descriptive and metric approaches, sometimes quantifying observable descriptive traits that are measurable (e.g., length of the mastoid). Size is a major factor influencing sex differences in the cranium and is believed to influence the development of bony structures such as the superciliary ridges, glabellar region, mastoid process and aspects of robusticity. Differences in robusticity thus form the basis of sexing using cranial morphology, with crania of small size and gracile features generally classified as females and the larger, more robust features classified as males. The aim of the study was to determine sex using Biauricular Breadth and Biasterionic Breadth in dry human skull bones. A total of 60 dry human skulls were used in this study. Biauricular breadth and biasterionic breadth were measured. The determination of sex is a common diagnostic procedure in forensic anthropology when the diagnosis is based on the observation of cranial morphology, each parameter becomes a test in such scenario. The present study was able to enhance determination of sex using biasterionic breadth and biaucoustic breadth. Analyses showed that cranial size and shape had significant differences between the sexes. Shape variables that best discriminate the sexes are predominantly those concerned with breadth of the face and cranial vault.
