Soft tissue landmarks used in the study; G, soft tissue glabella, the most prominent or anterior point in the midsagittal plane of the forehead at the level of the superior orbital ridges; Sn, subnasale, a point at the junction between the lower border of the nose and the beginning of the upper lip at the midsagittal plane; Pog′, soft-tissue pogonion, the most prominent or anterior point on the soft tissue chin in the midsagittal plane; Me′, soft tissue menton, the inferior soft tissue contour of the chin; N′, soft tissue nasion, the point of the deepest concavity of the soft tissue contour of the root of the nose; A′, soft tissue A-point, the most posterior (deepest) point on the curve of the soft tissue; B′, soft tissue B-point, the deepest point on the bony curvature along the anterior border of the soft tissue chin; Sti, stomion inferius, the most superior point of the lower lip; Sts, stomion superius, the lowest point of the upper lip; Pn, pronasale, the most prominent and anterior point of the nose; Li, labiale inferius, the median point in the lower margin of the lower membranous lip; Ls, labrale superius, the median point in the upper margin of the upper membranous lip.
