fa·cial an·gle

1. any of several variously named and variously defined anatomic angles that have been used to quantify facial protrusion;
2. in dentistry, the angle formed by the intersection of the orbitomeatal (Frankfort) plane with the nasion-pogonion line (inner lower angle), which establishes the anteroposterior relation of the mandible to the upper face at the orbitomeatal plane. Synonym(s): Frankfort-mandibular incisor angle

facial angle

[fāshəl]
Etymology: L, facies + angulus, a corner
the degree of protrusion of the lower face, assessed by measuring the inclination of the facial plane relative to the horizontal reference plane.
