Injection rhinoplasty is not permanent. The main methods of rhinoplasty are injection and prosthesis rhinoplasty. The injected material is fused with the surrounding soft tissues after injection, so its fatal disadvantage is that once the effect is not ideal or rejection occurs, it is not easy to take it out completely, and the effect is not lasting, so it will be absorbed by the human body. Prosthetic rhinoplasty is relatively safe. Choose a high-quality rhinoplasty prosthesis, carve your nose shape on the spot, and then make a small incision in the nasal cavity, which passes through the middle part of the nasal cavity and is placed between the inner cortex and the outer cortex of the nasal cavity to achieve the effect of bulging. There will be no surgical trace after operation. Once it is not ideal, the prosthesis can be completely taken out, which is safe and has good plastic effect. Any operation is risky. Choosing high-quality prostheses and professional doctors can reduce the risk of surgery.
