Communicate with the doctor before rhinoplasty, let the doctor know your condition and avoid medical accidents. The doctor will also help you do a comprehensive examination of vital signs such as blood pressure. Taking cardiovascular drugs such as aspirin and platelet aggregation inhibitor will increase intraoperative bleeding, make it difficult to stop bleeding, and may also cause postoperative bleeding and hematoma. You should inform your doctor before the operation and stop taking it. If the wound healing of diabetic patients is slow and easy to cause infection, please consult an endocrinologist before operation, carefully brush the incision symptoms after operation, and postpone stitches removal if necessary. Patients with acute inflammation such as abscess and upper respiratory tract infection, and patients with symptoms of nasal infection such as acne should postpone the operation.
