Onlay graft
This is a graft that is used to lift or augment the nose. It can be comprised of cartilage taken from the septum, ear, or rib. This graft lifts the bridge up for cosmetic purposes during primary or revision rhinoplasty.
This is most often done in Asian or African American rhinoplasty where the dorsum (bridge) needs to be built up. There are multiple ways to do this, and sometimes the onlay graft is used to deal with small depressions for camouflage purposes.
