Quick Summary

Mesaticephaly refers to a skull shape that is neither long and narrow (dolichocephalic) nor broad and short (brachycephalic). Instead, mesaticephalic skulls are described as being nearly oval when viewed from the top. This classification is determined by the cephalic index, which is calculated by dividing the skull's breadth by its length and multiplying by 100. A cephalic index between 75 and 80 typically indicates a mesaticephalic skull, which is common among populations such as Europeans and Chinese. The term "mesaticephalism" itself denotes the quality or state of having this particular skull shape.12
