Anterior Facial Depth
The angle at the nasal-wing base between the ear reference and the lower eyelid.
What is measured
The calculation
Angle: tragus → subalare → lower-eyelid landmark
Side view / Measurement guide
Follow the measurement
Dots mark the landmarks. Lines show how the measurement is taken.
In these guides, nasion means the nasal root, subnasale the nose base, and pogonion the most forward chin point. Frankfort refers to the direction from the ear-opening landmark to the lower orbital landmark.
Why it matters
This links three regions of the side face. The ear, nasal wing and eyelid positions all affect the opening of the angle, providing context about their arrangement.
- Lower: the ear and eyelid directions form a more closed angle.
- Higher: those directions spread farther apart.
Where the idea comes from
FaceIQ adaptation
This is a FaceIQ photographic construction. Clinical profile analysis provides context, but the cited work does not validate this exact landmark formula or its scoring range. [1]
A worked example
If the two rays from the nasal-wing base are separated by 70°, the measurement is 70° regardless of their lengths.
Example values explain the calculation. They are not a target range and are not measurements of the schematic above.
