Extended L-Framework: An Innovative Technique for Reconstruction of Low Nasal Dorsum by Autogenous Costal Cartilage Graft

Congenital, iatrogenic, and traumatic etiologies can produce a deficient nasal dorsum requiring dorsal augmentation. Traditional techniques for dorsal augmentation as onlay dorsal graft, cantilever graft, or conventional L-framework usually have less stability and produce a rigid lobule if the single unit framework extends to the tip. Because of abundant volume and relative ease of harvest and carving, the autogenous rib cartilage has been considered the graft of choice for dorsal nasal augmentation when structural support is necessary and sufficient septal cartilage is not available
