Figure 3. Measured distances and angles. Distance from the Gonion-gnathion (Gn) to cervical point (C) (Gn-C), from Gn to labiale inferioris (Li) (Gn-Li), from C to the visible thyroid cartilage (T) (C-T). Mental angle (MA): an angle formed by a line connecting glabella (G) and pogonion (Pg) and a line from the menton (M) to C. Cervical angle (CA): an angle formed by a line from the M to C and a line from C to T
