Collapsed nose can be improved by hyaluronic acid filling, cartilage rhinoplasty, and rhinoplasty with prosthesis under the guidance of professional doctors. 1. Hyaluronic acid filling: the main component of hyaluronic acid is hyaluronic acid, which has the advantage of high safety. Through the injection of filling, it can shape the nose well, achieve the effect of local fullness, and effectively improve the phenomenon of collapsed nose. However, it needs to be injected regularly, and the effect can be maintained for about 6 to 12 months. 2. Cartilage rhinoplasty: first of all, we need to take out part of our own ear cartilage tissue, and then after special processing, separation, placed into the bridge of the nose, the tip of the nose, so as to achieve the effect of the nose, to improve the symptoms of the collapsed nose, so that the nose looks firmer. 3. Rhinoplasty with prosthesis: mainly using silicone and other expanded material, the material is placed behind the bridge of the nose to raise the flat and collapsed bridge of the nose to achieve the effect of a more beautiful nose. However, due to the hardness of the silicone material, it may have a raw feeling when touching. In addition autologous fat filling, threading and other methods also help to improve the collapsed nose. A collapsed nose is not a disease and usually does not need to be treated. If you have aesthetic needs, it is recommended that you seek professional medical help in person and choose the appropriate treatment for your situation.
