Many techniques for cleft lip repair have been reported, but these techniques do not consider the contour lines of the upper lip and, in fact, destroy them. The upper lip has complicated contour lines including the vermilion free margin, vermilion border, upper lip horizontal groove (upper lip groove), philtrum (dimple and columns), nostril sills, and nasolabial grooves. Incision lines should be designed so that the postoperative scars do not cross these contour lines. We feel that our incision lines and postoperative scars provide better aesthetic results and diminish hypertrophic scar formation.
