Silicone prosthesis is no stranger to everyone. The "old buddy" of rhinoplasty surgery is mostly used for the design and filling of mountain roots. Different from before, the current silicone prosthesis is closer to its own nasal cartilage in terms of support and durability. Some prostheses even solve the small problem of light transmission and are very cost-effective materials in rhinoplasty.
Auricular cartilage is characterized by strong elasticity and relative softness. As Barbie's nose began to be sought after, it was more used to shape the tip of the nose. On the one hand, the supporting force is enough to make the tip of the nose more rigid, on the other hand, it has certain elasticity and softness, and there will be no sense of disobedience. But also has a certain regeneration ability, so there will be no problem of later shrinkage. But the ear cartilage is "small" after all, and it is not suitable to put it in the mountain root.
So to sum up, the combination of the two materials is better.
I hope my answer can help you.
