In addition to the necessary routine examination and the same precautions as other operations, hunchback patients should also pay attention to whether their nasal septum is bent. Due to the serious curvature of nasal septum, it should be corrected before hump nose plastic surgery. At the same time, we should also pay attention to whether there is infection in the nasal cavity and sinuses. If so, we need treatment and control before operation. In addition, three days before operation, we should use anti-inflammatory liquid to drip nose, trim nose hair, keep nasal cavity clean and reduce the chance of postoperative infection.
