Suggestion: Hello, 1. Non-surgical rhinoplasty: refers to injection rhinoplasty. This is a non-invasive operation. For example, injecting hyaluronic acid and other filling materials into the nose to fill the parts that are expected to increase, such as the back of the nose and the root of the nose, to help fill the defect and improve the phenomenon of low nose bridge. Injection rhinoplasty has a short recovery time and will not affect our normal life and work. It is an ideal choice for patients with mild rhinoplasty. 2. Prosthetic rhinoplasty: refers to rhinoplasty with solid materials such as silica gel or polytetrafluoroethylene, which is the most commonly used rhinoplasty method at present. Silica gel has the advantages of stable performance, low irritation, moderate texture, easy shaping, difficult deformation and easy removal after operation. Expansive materials have the advantages of good histocompatibility, tissue growth such as micropore and opacity. Solid material rhinoplasty can be combined with autologous cartilage, especially at the tip of the nose, which is convenient for shaping. 3, autologous cartilage rhinoplasty: autologous cartilage rhinoplasty is generally combined with artificial materials to improve the tip of the nose and nasal columella, autologous cartilage is often taken from the ear, nasal septum and costal cartilage. The cartilage of these three parts will not affect the appearance and function of the donor site, and the incision is hidden and small, so it is not easy to be found. The advantages of autologous cartilage transplantation are good histocompatibility, the skin in the operation area can withstand greater tension, the graft is not easy to be infected, and the graft has a certain hardness. There will be a small amount of absorption after autologous cartilage transplantation, but generally it will not absorb too much, which will affect the appearance.
