Rib cartilage rhinoplasty is completely autologous tissue, with no rejection, which is very safe. Compared with prosthesis, costal cartilage has no rejection and adverse reactions. The main disadvantage is that the chest wound needs to be re-cut, with minor trauma. Bone is still living tissue, so it is also in danger of deformation. Cartilage can only be used for rhinoplasty after removal, and the recovery time of nose and ribs is different, so it will take some time for the whole nose to recover completely.
