Expansive body and silica gel are both medical rhinoplasty materials, which are different materials. At present, both prostheses are safe and reliable by clinical verification.

The advantages of silica gel are:

1, silica gel is softer and has a longer life.

2. Strong anti-infection ability.

3. Good biocompatibility.

4. The probability of infection and rejection is low.

Disadvantages are:

1, if the silica gel is too thick, it is easy to produce light transmission and redness on the back of the nose, including displacement.

2. It is not easy to fuse with the tissue in the body, which will form a capsule around the prosthesis, and some patients will cause capsule contracture.

3. When some people have thin tissues, there is light transmission in the sun, which is inevitable.

The advantages of puffing are:

1, the compatibility and adhesion of the tissue are very good. Because this prosthesis has micropores, tissue can grow into this prosthesis, which is relatively safer.

2. Generally, there will be no sliding and light transmission.

Compared with silica gel, the disadvantages are:

1, swelling and hardening.

2, easy to be infected
