Sexual dimorphism with regard to size and nonuniform shape of the human skull was studied by means of a three-dimensional TPS analysis based on 42 landmarks of the skull. Significant differences with regard to both size and nonuniform shape could be substantiated. These results, although preliminary, suggests that the muscles of mastication and neck constrain the possible sexual shape variation encompassing anteroposterior as well as superoinferior dimensions of the skull, but not the lateral dimensions.
