Figure 6

Lip diastasis and nostril measurements performed: (A) stereophotogrammetric image with texture map showing the four major landmarks, white = labiale superius (ls), blue = crista philtri landmark (cph), yellow = subnasale’ (sn’) and red = subalare (sbal). (B) Stereolithography converted image (C) defect cropped using four landmarks. (D) Upper and lower boundary limits were defined by bridging sn’ and sbal, ls and cph. (E) The cleft area was filled (blue) using the boundaries defined by D. (F) Nostril areas defined in blue. Measurement of nostril (G) height and (H) width in 3dMDvultus.
