Angular cephalometric measurements used in this study. (a) Angular measurements of “nasolabial angle” (the angle between “columella”, “subnasale” and “upper lip”) and “lower face–throat angle” (the angle between the line through “subnasale” to “soft-tissue gnathion” and the line through “soft-tissue menton” to “throat point”). (b) Angular measurement of “nose prominence angle” (the angle between “tip of nose”, “soft-tissue nasion” and “subnasale”) and “soft-tissue profile angle” (the angle between “soft-tissue nasion”, “subnasale” and “pogonion”)
