Whether silicone rhinoplasty can be placed permanently depends on the specific situation. Generally speaking, if the prosthesis does not cause infection or rejection reaction and other abnormalities, it can be placed for a long time. 1. The duration of placement of the prosthesis after silicone rhinoplasty is related to whether or not the cosmetic patient has an adverse reaction. Generally speaking, silicone prosthesis in the body can be placed for about 15-20 years at the longest. 2. After 15-20 years, the prosthesis does not necessarily need to be taken out directly, but an evaluation of the body needs to be carried out. If the silicone gel prosthesis does not have any adverse reaction to the person and maintains a relatively good appearance and relative shape, the prosthesis can be continued. If there is discomfort after silicone rhinoplasty, it is recommended to go to the hospital in time for symptomatic treatment.
