Rhinoplasty with costal cartilage is certainly better, and it is more natural and less dangerous. If the costal cartilage is taken from your body, it has relatively no side effects. The effect is the same. But relatively speaking, there are certain dangers. After all, a certain amount of bone tissue is taken from costal cartilage. If it is not taken well, it is dangerous. If silica gel is used, it has great side effects. Relatively speaking, it may be allergic, which may cause nasal swelling or allergic rhinitis in the later stage. The rib nose made by my friend at Zhang Gaogui's house in Hohhot is very effective. It looks good to me.
