Measurement | Definition |
|---|---|
Upper Lip Height (Sn-Sto) | Height of the entire upper lip measured from subnasale to stomion superius |
Lower Lip Height (Sl-Li) | Vertical measurement of the lower lip below the vermilion |
Upper Vermilion Height (Ls-Sto) | Height of the upper lip vermilion measured from labrale superius to stomion superius |
Lower Vermilion Height (Li-Sto) | Height of the vermilion segment of the lower lip |
Philtral Length (Sn-Ls) | Distance between the nasal bone/base and midline upper lip vermilion border |
Philtral Width (CphR-CphL) | Distance between the philtral ridges, measured just above the vermilion border |
Nasolabial Angle (Prn-Sn-Ls) | Angle at subnasale subtended by side columella—labrale superius |
Labial Fissure Width (Lch-Rch) | Distance between the commissures of the mouth |
Facial Convexity (Gl-Sn-Pg’) | Angle at subnasale subtended by side glabella—pogonion |
Facial Height (N’-Gn’) | Vertical height (length) of the face or viscerocranium |
Nasal Angle (N’-Prn-Sn) | Angle at pronasale subtended by side nasion – subnasale |
Nasofrontal Angle (Gl-N’-Prn) | Angle at nasion subtended by side glabella—pronasale |
