Craniofacial landmarks, established planes and dihedral angles used in this study. (a-c) Landmark LO, LP and RP formed a horizontal reference plane (H plane). (a) Landmark LJ, LP and RP formed a jugal plane (J plane). The dihedral angle between J plane and H plane was defined as θJ. (b) Landmark LZ, LP and RP formed a zygomatic plane (Z plane). The dihedral angle between Z plane and H plane was defined as θZ. (c) Landmark LS, LP and RP formed a squamosal plane (S plane). The dihedral angle between S plane and H plane was defined as θS.
