I’m planning doing a rhinoplasty, what is the difference between ear cartilage and rib cartilage?

Rib cartilage is the best graft for augmentation rhinoplasty in an ethnic patient who has had all of their septal and ear cartilage used.
Doctor Chiu of Fabulous clinic in Taiwan is good at rib cartilage rhinoplasty.

Actually, ear cartilage is more likely to warp than rib cartilage because is thin and softer than rib. The choice really depends on what the cartilage is being used for.

Explain in great detail, thank you all !
