Hello, rhinoplasty is the plastic art of human appearance. In order to ensure the safe and smooth operation, it is most important to eliminate infection. Therefore, before the operation, it is best to have no inflammation on the face caused by bacterial diseases, such as folliculitis, carbuncle, acne and acute ophthalmia. In order to prevent infection, women can't have surgery during menstruation. In addition, it is best to take a bath the day before the operation. On the day of operation, wash the dirt and grease off your face with soap before going to the operating table to minimize the number of bacteria. Before the operation, you should also cut your nose hair and clean your nose. There are other diseases in the body before operation, which leads to low resistance, and it is easy to cause infection during operation, which affects wound healing.
