At present, the materials used for rhinoplasty are: silica gel, swelling, autologous cartilage, fascia, dermal flap, non-invasive injection and so on. So what is the most suitable material for the tip of the nose? There is no doubt that cartilage is autologous tissue and has better compatibility with the body. It belongs to cartilage like the nasal cartilage that supports the nose. The nose tip can be pulled down or raised to the required position, without any stimulation to the tissue, which completely conforms to the physiological theory and is most suitable for rhinoplasty.
