Silicone, as the most common rhinoplasty prosthesis, is easy to carve and safer, so it is used until now. However, it also has shortcomings, mainly the following surgical risks: 1. Rejection reaction: allergy and rejection may occur, which is related to personal constitution. If there is prolonged swelling, skin transparency, flow of yellow exudate, usually need to be removed; 2, translucent phenomenon: silicone is relatively hard, some people may appear translucent after doing it, and even the prosthesis can be seen; 3, peritoneal contracture: the prosthesis relative to the human body, it is a kind of foreign body, after putting it into the human body, the peritoneal membrane will be produced around the body, wrapping up the prosthesis; 4, prosthetic exposure: after a long time of rhinoplasty, the prosthesis may be from the nasal head, Nasal column or side of the nose, through the skin, may be related to the hardness of the prosthesis, the doctor’s technical level and improper postoperative care; 5, swelling and bruising: because rhinoplasty to separate a cavity in the dorsum of the nose, and silicone gel prosthesis placed in it, so there is a trauma of the surgical operation, postoperative swelling and bruising can be caused; 6, the nose is not beautiful: rhinoplasty may appear after the deflection, asymmetric and other rhinoplasty failure phenomenon; 7, Foreign body sensation: using the prosthetic material to fill the nose, the foreign body sensation is more obvious from 1 week to 3 months after the operation, but usually returns to normal after 3-6 months. Therefore, it is recommended that candidates should choose a professional doctor from a regular institution to perform rhinoplasty. If the surgeon designs, sculpts and separates the cavities well during the surgery, the prosthesis stability is relatively good and usually does not produce great risks.
