The main materials used for rhinoplasty are silicone as well as expanders. After the implantation of the prosthesis, the following problems may occur: 1. Infection and rejection: after the infection occurs, it is necessary to use a sufficient amount of antibiotics to treat it under the diagnosis of the doctor. If the infection is more serious, the prosthesis needs to be removed if necessary. In addition, once the prosthesis rejection occurs, the prosthesis also needs to be removed immediately; 2, long-term swelling and bruising of the nose: rhinoplasty surgery requires separating a cavity on the back of the nose in order to implant the prosthesis. Due to the trauma of the surgery, postoperative swelling and bruising are inevitable, but will usually recover gradually. If there is prolonged swelling, bruising, pain aggravation, etc., you must contact the surgeon in time for relevant treatment; 3. Crooked nose: it may be related to your own conditions, such as crooked septum, crooked nasal columella, etc., and it may also be caused by the surgery, such as insufficient separation of cavities, improper sculpture of the prosthesis, etc.; 4. Exposure of the prosthesis: there are many factors leading to the exposure of the prosthesis, such as separation of cavities that are too shallow, prosthesis sculpture is too thick, too sharp, or L-type silicone prosthesis is used. In addition, there is also a great relationship with the postoperative impact on the nose, which can be repaired after removing the prosthesis.
