How long a rhinoplasty can be maintained needs to be judged according to the individual’s body type and the material of the prosthesis. In most cases, if there is no abnormal situation can be placed in the body for a long time, but if there is local bleeding and other abnormal performance will need to be removed in time. Of course, the retention time is also related to the material of the prosthesis, tumescent can often be maintained for a long time, while silicone prosthesis can generally only last about 15 years. 1, if the surgery is more successful, rhinoplasty prosthesis does not cause obvious complications, nor cause adverse reactions of the body, or cause skin thinning, prosthesis exposed phenomenon, can be placed in the body for a long time, and can be maintained for a long time. However, it should be noted that some abnormalities can occur after rhinoplasty, such as displacement or the presence of local bleeding, hematoma, skin petechiae, etc. Some people have allergic and rejection reactions to the prosthetic material, which may be manifested in the early stage by repeated swelling and redness of the skin where the prosthesis is placed, and in the later stage by thinning of the skin and exposure of the prosthesis. The time that the prosthesis can be maintained also needs to be analyzed according to the material of the prosthesis, which is generally silicone or tumescent material. If the material of the prosthesis is tumescent, and the tissue has better compatibility, low rejection, can be maintained for a long time. If the prosthesis material is silicone, because silicone and its own tissue can not fuse with each other, so the prosthesis in the body to maintain about 15 years will have the possibility of silicone material degeneration, so within 15 years is a relatively safe range. In addition to the need to consider how long the prosthesis can be maintained, when doing rhinoplasty, you also need to consider the possibility of incision scar growth at the nasal margin. It is important to pay attention to the early application of anti-scar medication to minimize wound scar growth to ensure that a better rhinoplasty result can be achieved. After the rhinoplasty, you should pay attention to avoid strenuous activities, protect the nose from external pressure, keep the wound area clean and hygienic so as not to cause infection and affect the post-operative effect, and seek medical attention when discomfort occurs during the recovery period.
