In patients with very thick, stiff skin, there may be a tendency of local flaps to create a “bulldozing” effect, in which downward displacement of the alar margin results from the bulk of the primary flap pushing caudally. 1 In such cases, it is likely that some degree of pivotal restraint occurs, but this restraint is counteracted by a caudally oriented pushing effect by the thick primary flap. In these situations, the nostril margin not only may become displaced inferiorly but its normally arched contour may become distorted. Therefore, when using the long-flap modified Zitelli design.
