Nose reduction surgery is a common surgery in plastic surgery. By making incisions on both sides of the outer edge of the nose or in the nasal cavity, excess soft tissue and connective tissue are removed and the corresponding parts are trimmed to restore the nose to a compact size. Although the operation is a common surgery, the hazards that may result if an unprofessional surgeon is chosen to perform the operation mainly include the following: 1. Risk of anesthesia: mainly including anesthetic allergy and respiratory obstruction; 2. Risk of the operation itself: during the operation, if it is not done properly, it is likely to lead to infection, which is the most common clinical sequelae. Therefore, after the surgery, patients must go to the hospital for regular review, and if infection is found, actively help control the symptoms of infection through medication to avoid aggravation; 3. Incisional hyperplasia: Some patients have obvious hyperplasia, while some patients have inconspicuous hyperplasia, the degree of which varies from person to person. In order to reduce the incisional scar growth, candidates should pay attention to their postoperative diet, and must eat less seafood, mutton and fatty foods, and their diet needs to be light and avoid spicy and fried foods. For scars, anti-scar treatment, such as topical anti-scar ointment, is needed after surgery and anti-scar treatment needs to last for about 3 months.
