title: A cephalometric guide to the diagnosis of midface hypoplasia at the Le Fort II level.
abstract: A cephalometric study of the relation of the malar eminence to the A point has been made. It is proposed that the orbital-NA distance is of clinical importance in patients with SNA of less than 79 degrees in whom a Le Fort I osteotomy procedure is contemplated. The measurement of the angle SNO is a significant guide to the malar-maxillary relationship and will assist in complete cephalometric evaluation of these patients.
