Nose surgery is a surgery with high technical requirements and refinement, and carries a certain degree of surgical risk, which is usually related to the surgeon’s experience and the materials chosen during the surgery. Currently, there are many kinds of rhinoplasty materials in the market, if the doctor does not have rich experience and accurate judgment, and adopts unsuitable surgical materials, it may lead to the failure of comprehensive nasal surgery. Moreover, in the comprehensive nasal surgery, the materials need to be carved, cut, fixed and supported, if the doctor’s operating experience is not enough, it may also increase the risk of the surgery. Hematoma, bruising, infection, prosthesis rejection, prosthesis displacement, tissue necrosis, and poor nasal shape may occur after the comprehensive nasal surgery. If you want to reduce the risk of surgery, you need to go to a regular hospital to find a professional doctor for an interview and design a suitable surgical plan. It is recommended that you need to conduct a detailed examination and confirmation before the operation to ensure that there are no acute or chronic infectious diseases in the nose, that you are not in menstruation or pregnancy, and that you are not taking any anticoagulant drugs, and to conduct a blood test and a blood coagulation function test before the operation. After the operation, avoid eating blood-activating drugs and food, avoid trauma to the nose, and try to keep the nasal cavity clean to reduce the possibility of infection.
