Sex estimation: 3D CTA-scan based on orbital measurements in Turkish population

The orbit is an essential anatomic landmark and orbital measurements are one of the craniofacial parameters that could be used in sexual and ethnic estimation in terms of anthropologic studies. The aim of this study is to obtain and analyze data regarding the computed scans of orbital aperture measurements in Turkish population for sex estimation and for comparing with other populations. A total of 112 Three-Dimensional Angiography Computed Tomography scans of 52 female and 60 male subjects aged between 13 and 86 years were examined in terms of Orbital Width (OW) and Orbital Height (OH). Sexual dimorphism was analyzed using by discriminant function models. It was determined that both left and right OW and OH of males were significantly larger than females. While single variable used for sexual dimorphism, the most confidential variable was the left OW for males (71.7%) and the left OH for females (69.2%). When combined models were used, the left OW and OH model was the best one for both males (80.0%) and females (69.2%). Data obtained from this study showed that orbital measurements could be used to create a new data collection for Turkish population. However, it was seen that these measurements are not reliable parameters for sex discrimination. It should be better, if they are combined with other methods for sex estimation.
