Advantages of silica gel: low price, strong plasticity and wide application. Silicone gel can also be used for aquiline nose plastic surgery with prominent nose bridge.
Disadvantages: translucent, easy to slide, hard texture. After operation, the prosthesis may shake, fall off, skew or even break the skin and be exposed.
Advantages of swelling: the advantage of swelling is that its material is close to human nasal tissue, and its compatibility is good, and postoperative thinking is relatively natural. The tiny blood vessels can grow into the swollen body, so that the prosthesis is not easy to slide, the stability is improved, the rejection reaction is less, the material is opaque, the weight is light, there is no obvious falling feeling, and there is no compression and atrophy effect on bone tissue.
Disadvantages: the material is soft, which is not enough to provide structural support for raising the nose tip column. In case of problems, it is more troublesome to take out the prosthesis; The expanding microporous virus can enter, but the immune cells of human body can't. Once infection occurs, the prosthesis must be removed.
