this line is the change of color of the vestibular skin; below the marginal border, the color of the skin is the same as the nasal skin, but above that line, there is a transitional epithelium (from skin to the nasal mucosa) and the color is red; there­fore it is easy to locate the border of the alar cartilage following the line between these areas with different colors (Fig. 1.21). This line starts from the intercarti­laginous border and nishes before the medial wall of the nasal vestibule at the level of cleft side nasal dome (Figs.6.24 and 6.25). The intercartilaginous line is designed in continuity with the lateral end of the marginal marking and follows the intercartilaginous border (limen nassi) which is clearly identied. The extent of this marking is about 3–5mm in order to release the lateral border of the alar cartilage and allow the rotation of the composite ap (Figs.6.26, 6.27, and 6.28). Both lines are surrounding the alar cartilage to create the composite ap (com­posed by the vestibular skin and alar cartilage). The lateral wall of the nasal ves­tibule is preserved and prevents the development of lateral webs or scar contractures. The use of postoperative nasal conformers is optional using this technique because of the used limited incision.
