Figure 4.

Soft tissue angular and linear measurements: 1. Nasolabial angle: The angle formed between a line tangent to the base of the nose and a line tangent to the upper lip, 2. Ls to Sn-Pog′: the distance from labrale superius to Sn- Pog′ line (mm), 3. Li to Sn-Pog′: the distance from labrale inferius to Sn- Pog′ line (mm), 4. M.L.S: The maximum depth from a line connecting Pog′ and the lower li (mm) p, 5. Point A- Sn: the distance from point A to Subnasale (mm), 6. Is- U lip: the distance from incision superioris to the upper lip (mm), 7 Ii- L lip: the dimension from incision inferioris to the lower lip (mm), 8. Pog- Pog′: the dimension from hard tissue Pog to soft tissue Pog (mm), 9. Z angle: the angle between Frankfort plane and a line connecting Pog′ and the most protrusive lip point
