Correcting a flat or saddle nose is one of the most popular aesthetic procedures done for Orientals, comparable to the correction of a hump nose for Occidentals. Presently, because of its advantages, silicone rubber is chosen most frequently for nasal augmentation. However, there is a possibility of extrusion with this material, most likely at the tip and columella. One of the solutions for this type of problem is to keep the protecting soft tissue of the nose from the implant. The conchal cartilage is effective, because it has important characteristics such as a curved surface, thinness, and a high percentage of survival by virtue of its low anaerobic metabolism. We proved its validity through experimentation with 30 rabbits. Two ear cartilage grafts and a sheet of tensor fascia lata graft overlapped with precut Silastic® blocks and then placed in the dorsal pockets of rabbits. One cartilage graft has the perichondrium, but the other one does not. The extra cartilage is for the control group. They were evaluated histopathologically for 12 weeks.
The results were as follows:
1. All of the cartilage with perichondrium, even the ones on the Silastic® bloock
