The adult orbital rim is known to exhibit sexual dimorphism. However, the development of the orbital sexual dimorphism is poorly understood. Moreover, there has been little study of sexual dimorphism in the supraorbital rim in the early development of fontal bones. Therefore, this study assessed 188 supraorbital rims among black and white females and males of fetal, neonatal, and infantile age. The population consisted of 47 black female, 36 white female, 54 black male, and 51 white male supraorbital rims. Canonical variate analysis revealed statistically significant contour differences among all groups (p<0.0001). Further, all groups separated by Mahalanobis distances greater than 11 except for black females and white males (Mahalanobis distance = 6.84). The results of this study suggest that sexual dimorphism of the supraorbital rim exists within and between races, even among fetuses.
