Table 2 The facial angle

From: Correlational research on facial and clinical characteristics of adolescents with obsessive-compulsive disorder

Facial angle Abbreviation Measurement of facial diameter
Full surface coign g-prn-pg’ The angle between the base of the nose, tip of the nose, and front of the chin reflects the protrusion of the face including the nose
Surface coign g-sn-pg’ The angle between the base of the nose, point of the nose, and point of the front of the chin reflects the protrusion of the soft tissue profile
Upper lip and chin process angle ula-ns-pos The angle between the protrusion of the upper lip and base of the nose, and between the base of the nose and anterior point of the soft tissue, indicates the protrusion of the upper lip relative to the face
Lower lip and chin process angle lla-ns-pos The angle between the protrusion of the upper lip and base of the nose, and between the base of the nose and anterior point of the soft tissue, indicates the protrusion of the upper lip relative to the face
Nasofrontal angle g-ns-prn The dorsal line of the nose intersecting the inclined plane from the forehead to the root of the nose reflects the degree of depression of the root of the nose or degree of protrusion of the forehead
Angle of nasal process n-prn-sn The included angle of the line connecting the base of the nose-tip point-under-nose point is the angle between the dorsal line of the nose and the line of the columella. Reflect the protrusion of the nose itself
Chin Angle of upper and lower lip ula-ns-lla The angle between the protruding point of the upper lip and the base of the nose, and the protruding point of the base of the nose and the protruding point of the lower lip, indicating the relative position of the upper and lower lips
Nasolabial angle cm-sn-ula The intersection angle of the line between the columella point and subnasal point, and the line between the subnasal point and upper lip protrusion, reflects the morphological changes and forward and backward positions of the nose and upper lip
Chin lip groove angle pos-sl-li The angle between the point of the lower lip, point on the chin, and the front of the chin indicates the degree of lower lip protrusion relative to the chin
