Abstract
The septal advancement flap is introduced as a new technique to support the nasal base in preservation rhinoplasty. The SAF is a septal flap composed of the caudal septum in continuity with the high strip incision used in dorsal preservation. The technique is supported with a strut of cartilage between the medial crura. The SAF has been evaluated using mathematical models and a finite element mesh to verify the stability of the graft. The SAF is compared with the caudal septal extension graft and columellar strut and discussed in the context of all three options for stabilizing the base of the nose in rhinoplasty. The pros and cons of each as well as details about refinements of the caudal septal extension graft are discussed.
