How to correct a flat nose? A flat nose means that the bridge of the nose between the eyes is not obvious and is basically the same as the corner of the eye. This is what people usually call a flat nose. It's like sitting badly when I was a child. Will affect the future spine. Method of correcting nasal collapse: 1. Implanting silica gel prosthesis for rhinoplasty: Implanting silica gel prosthesis into the nose by surgery can achieve the purpose of increasing the back of the nose. Silicone prosthesis is an ideal material at present, which has good biocompatibility, little stimulation to tissues, easy carving, low price and wide application. Second, the expansion implant rhinoplasty: the expanded PTFE material is implanted into the nose through surgery to achieve the effect of rhinoplasty. The expanded material is flexible in texture, and the nose looks natural and beautiful after operation, but it is more expensive. Third, autologous cartilage transplantation for rhinoplasty: autologous cartilage tissue is transplanted to the nose and the external nose is padded. Donor cartilage is usually taken from ear cartilage, nasal septum cartilage or costal cartilage. Autologous cartilage tissue transplantation will not cause rejection, with high survival rate and realistic and natural appearance, but it may be slightly absorbed and deformed after a long time. In addition, it is very painful to take cartilage from the recipient twice. Fourth, injection rhinoplasty: The principle of injection rhinoplasty is actually similar to that of surgical rhinoplasty, and the rhinoplasty effect is achieved by filling substances into the skin tissue of the nose, but the difference is that injection rhinoplasty does not need to cut the skin tissue of the nose, only injection can achieve the filling effect.
