Subdorsal Cantilever Graft: Indications and Technique.

The subdorsal cantilever graft (SDCG) is a costal cartilage graft that is positioned below the nasal dorsum to control the position of the nasal bones and middle nasal vault. SDCG type A is used to raise the middle nasal vault and caudal nasal bones to correct the saddle nose deformity. SDCG type B can be used to raise the entire dorsum of the nose (radix, bony vault, and middle vault) in the ethnic augmentation rhinoplasty patient. This article will discuss the indications and technique of the SDCG in dorsal preservation rhinoplasty.
