First, the indications for rhinoplasty are not properly grasped. For example, simple rhinoplasty for complex saddle nose will not be satisfactory.

Second, improper selection of materials often leads to xenophobia, which really can't achieve the effect of comprehensively correcting nose shape.

Third, insufficient preoperative preparation, such as improper trimming of nose hair, inadequate disinfection of nose and materials or overdue infection.

4. Improper material dressing may lead to long, short, too high, too low and irregular nose shape, or the tunnel at the back of the nose is too shallow, not straight, layered or improperly cut, which may easily lead to bad nose shape or infection.

5. Poor postoperative cooperation and irregular filling of materials during the operation will also lead to poor nasal shape, and improper postoperative treatment or repeated surgery in a short time will often lead to adverse consequences.

For rhinoplasty, you should consult a doctor in a regular hospital face to face, and the beauty seeker should know the expected effect and operation process in detail before operation to reduce the risk of failure.
