Facial Index

one of the anthropological characteristics used in anthropometry—the ratio of the height of the upper face, that is, without the lower jaw (1), or of the entire skull, with the lower jaw (2), to the bizygomatic expressed in percent. The following landmarks exist on the skull for index (1): euryene (up to 49.9), mesene (50.0–54.9), and leptene (55.0 or more). The landmarks for index (2) are euryprosopia (up to 84.9), mesoprosopia (85.0–89.9), and leptoprosopia (90.00 or more). On living persons the second index is used with the following landmarks: euryprosopia (up to 84.0), mesoprosopia (84.0–87.9), and leptoprosopia (88.0 or more). The facial index varies in different groups of population; it is taken into account in anthropology when distinguishing racial types.
