Autologous cartilage rhinoplasty uses human cartilage tissue to achieve rhinoplasty effect, autologous cartilage has a certain degree of hardness and flexibility, and does not require a large number of blood vessels for nutrition, it is a safer way of surgery, and its risk is less likely to appear. However, there are risks in any surgery, and autologous cartilage rhinoplasty, like other rhinoplasty, may have bleeding, infection, swelling, bruising, bending and deformation, unattractive appearance, cartilage absorption and so on. In addition to the above risks, the prerequisite for autologous cartilage rhinoplasty is that it should not exceed the tolerance of the nasal skin, if it exceeds this range, it will lead to complications such as perforation and incomplete skin healing. If the autologous cartilage leaves the original growth area, there will be a certain deformation rate, and the longer the graft, the greater the possibility of deformation. Generally, autologous cartilage rhinoplasty under the operation of professional doctors in regular institutions can avoid the above risks to the maximum extent. In addition, it is recommended that candidates wash their face of dirt and grease before surgery to reduce the number of bacteria, men should also trim their nose hair and clean their nasal cavity, and women should avoid menstruation. After surgery, it is important to avoid touching the surgical incision with your hands and avoiding water on the incision, and to minimize activities to prevent displacement of the stent. It is also necessary to pay attention to dietary adjustments, avoid spicy and stimulating food, and avoid sun exposure and violent impact within two months after rhinoplasty with autologous cartilage, so as not to cause swelling and infection.
