There are two kinds of rhinoplasty materials:

Injection rhinoplasty and prosthetic rhinoplasty. Rhinoplasty with hyaluronic acid by injection can achieve the effect of nose shaping. Hyaluronic acid, formerly known as hyaluronic acid, is a kind of macromolecular polysaccharide, which belongs to a kind of human dermal tissue. Hyaluronic acid used in medicine is purified. Advantages: Hyaluronic acid rhinoplasty is a minimally invasive operation, with small wound, quick recovery, short operation time and low allergic rate, which is completely harmless to human body. When the molding is not satisfactory, it can also be dissolved with hyaluronidase. Disadvantages: short stay in the human body. Usually it will be decomposed by the human body in 8 months to 3 years, requiring multiple injections. Avoiding high temperature environment after operation, such as sunbathing or sauna, can delay the absorption of hyaluronic acid. Suitable crowd: people who have a good nose foundation and only need fine tuning. Slight nose collapse can be done. If it is accompanied by nose and alar hypertrophy, it is necessary to increase the ratio to achieve the desired effect. Why do you say that hyaluronic acid rhinoplasty is only suitable for people with good nose shape, who only need fine adjustment? Because our skin is tense, when we inject too much hyaluronic acid, hyaluronic acid will spread to both sides of the nose under the tension, which will not only improve the height, but also widen the nose. Prosthetic rhinoplasty includes silica gel, swelling, autogenous bone (ear cartilage, nasal septum cartilage and costal cartilage), ear cartilage and nasal septum cartilage because of small amount and support.

Advantages of silicone: silicone has good elasticity, is easy to carve, and is cheaper than other prosthetic materials. It is completely non-toxic to human body, with few adverse reactions. It will not be absorbed after being implanted into human body. As long as it is not infected or displaced, it can be implanted in the nose for a long time, and it can last for about 2 years at the longest. The operation time is short and the recovery is faster. Because it will not be absorbed, it is convenient to take out the prosthesis in the later stage, and the prosthesis can be taken out completely. Disadvantages: because it will not be absorbed by the human body, the prosthesis can not be fused with autologous tissue after implantation, and it is easy to shift, fall or even be exposed. Because it is not autologous tissue, it is more prone to rejection after being implanted into human body. Advantages of bulking: soft texture, more realistic feel, good stability and good integration with tissue. There is no design shape in advance, so the carving space is large. Disadvantages: The swelling body is a porous structure. After being implanted in our body for a period of time, capillaries or tissues will grow in the pores of the nose, which is difficult to take out once problems occur. There are some problems, such as not designing the shape in advance, carving in advance, aseptic operation or lax disinfection, which are easy to cause infection. Advantages of autogenous bone: it belongs to autologous tissue and will not be rejected. After implantation, it can grow together with the nasal tissue, generally without light transmission and displacement. The effect is more real and lasts longer. Disadvantages: taking cartilage is equivalent to adding an extra operation to increase the wound. It requires high carving skills for doctors, and it is difficult to repair failures. Bones cannot regenerate after collection. Costal cartilage has biological memory, there will be probably.
