Regions | Proportional Indices |
---|---|
Nose | \( Nasal\ index=\frac{Width\ of\ the\ nose}{Height\ of\ the\ nose}\times 100 \) |
\( Nasal\ tip\ protrusion\ width\ index=\frac{Nasal\ tip\ protrusion}{Width\ of\ the\ nose}\times 100 \) | |
Orolabial | \( Upper\ lip\ width\ index=\frac{Height\ of\ the\ upper\ lip}{Width\ of\ the\ mouth}\times 100 \) |
\( Skin\ portion\ upper\ lip\ index=\frac{Height\ of\ the\ cutaneous\ upper\ lip}{Height\ of\ the\ upper\ lip}\times 100 \) | |
\( Upper\ vermilion\ height\ index=\frac{Vermilion\ height\ of\ the\ upper\ lip}{Vermilion\ height\ of\ the\ lower\ lip}\times 100 \) |
