Figure 9: Tripod modell of the nasal tip according to Anderson. The lateral crura (light grey and dark grey) represent two legs of the tripod, whereas the two parallel medial crura represent the third leg. The projection and rotation of the tip may be altered by lengthening or shortening of individual legs: downward rotation and retroposition by relocating the columella posteriorly (a). Additional shortening of the lateral crura increases the deprojection of the tip and counterbalances the downward rotation (b). Increased projection and rotation by repositioning the columella anteriorly (c). Additional shortening of the lateral crura further rotates the tip and counterbalances the icrease in tip projection (d). Maximum rotation is achieved by a rostral repositioning of the columella and shortening of the lateral crura (e).
