The landmarks and reference coordinate system. PoR = right porion; PoL = left porion; OrR = right orbitale; OrL = left orbitale; N = nasion; S = sella; LoR = right lateral orbital point; LoL = left lateral orbital point. The positive x, y, and z coordinate values indicated the front, left, and superior orientation, respectively.
