Polytetrafluoroethylene carbon, commonly known as swelling, has the advantages of no allergy and immune rejection, low incidence of inflammation, and tissue can grow into it. Because it is soft and easy to bend, it feels natural after implantation. This material is made in China, not imported. The imported material is GORE-TEX produced by Gore Company of the United States. The common specification is 1.5cm*6.5cm*4.5mm, and the domestic material is not listed.

Second, as a prosthetic material, the advantages and disadvantages of the expansion body.

Common prosthetic materials on the market are nothing more than silica gel and swelling. The advantages and disadvantages of swelling are as follows:

Third, rhinoplasty about infection:

Regarding whether swelling is easy to be infected, because there are micropores on the swollen surface, some autologous tissues can grow in, which is beneficial to the fixation and beauty of the prosthesis. However, if the swelling is exposed to the body for a long time, bacteria entering the micropores will increase the infection rate of rhinoplasty. If the nose is oily and forms deep swelling, it will be easily infected if it is compatible with the prosthetic cavity, so it is reasonable to worry about infection.

Of course, if rhinoplasty wants to prevent infection, there are still rules to follow. Rhinoplasty doctors can minimize the chance of infection as long as they follow the following steps:

First, doctors must be familiar with swelling, and the carving time should not be too long, usually 10 to 15 minutes.

Second, after the large pieces are carved, they should be placed in sterile water and not exposed to the air. At this time, the disinfectant will also enter the micropores to prevent infection.

Third, facial disinfection should be done more thoroughly, pay attention to the oil in nostrils and face, and the whole rhinoplasty operation must be strictly sterile. Fourth, rinse the prosthesis cavity before taking a vacation, generally using Qingda.

Fifth, beauty seekers should pay strict attention to the waterproof of incision before and two or three days after suture removal.

Fourth, will rhinoplasty harden after a long time in the nose?

One advantage of swelling is that it is softer than silica gel. With the passage of time, the expanded material will not harden, but it will lose its elasticity to some extent.
