1. Prosthesis displacement: In rhinoplasty, the previous prosthesis needs to be removed for plastic surgery due to the placement of the prosthesis or external reasons.

2. Prosthesis exposure: Prosthesis leakage is generally common in L-shaped silicone prostheses. This is because the material is placed in the wrong position, the size of the implanted material is wrong, and the skin tissue has changed. You need to take it out again at this time.

3. Light transmission of prosthesis: Generally, the skin tissue changes, and the skin tissue becomes thinner and thinner, resulting in light transmission of prosthesis. It is necessary to take out the prosthesis by surgery, slightly adjust the level and position of the prosthesis according to the specific situation, and then implant a new prosthesis as needed.

4. Infection: If the nose is infected, it will cause damage to our organization. No matter what kind of material or other reasons cause the infection, once it happens, it must be controlled as soon as possible, and the prosthesis should be taken out as soon as possible if necessary.
