The expanded material is made of polytetrafluoroethylene (PTFE) dispersion resin by stretching and shaping, which is the most suitable artificial material for human body. The unique microporous structure, non-toxic, non carcinogenic, non sensitizing and other side effects, has compatibility with human tissue, does not shift after surgery, nose perforation and so on.
In addition, e-PTFE is often used in the field of surgery and medical treatment, including artificial blood vessels, meningeal patches, surgical patches, surgical anti adhesion film, vascular stent coating, medical suture, etc.
Is swelling shrinkage present?
The swelling material will not shrink, but because of its special pore like node, which has the characteristics of water absorption and surrounding tissue growth, its volume will slightly increase after the operation.
Can't puff come out?
It can be taken out completely, but the method is different from silica gel, and blunt peeling is required, which is not complicated for experienced doctors.
Is swelling easy to infect?
Puff infection does exist objectively, but the cause of puff infection is not because the puff material itself is not good, nor because of personal constitution, but because of the bacteria on it. The bacteria are mainly from the operation. The same is true for silicone implants. The puff is sealed before use and in sterile state. It will be unpacked before use. The swelling and silica gel can not be used directly. Doctors will carve according to the specific needs of the patients, and even the air in the operating room can not guarantee absolute sterility. The longer the exposure time in the air, the higher the probability of infection. Therefore, we must choose regular medical institutions and experienced doctors to accurately sculpt the prosthesis during the operation, reduce the exposure time, and improve the disinfection operation and facilities in the operating room, so as to avoid infection to a large extent.
What are the differences between expanded nose augmentation vs silicone nose augmentation
1. The carving of silica gel and expanded body is difficult and easy to be different
Silica gel and expanded body are both prostheses, which need to be carved by doctors before they can be implanted into the back of the nose, so as to achieve the purpose of beautifying the nose. Because of the different materials, the carving technology of the expanded body is more difficult than silica gel, which is why the surgeons who can do the expanded body will certainly do the silica gel nose augmentation, while the surgeons who can do the silica gel will not necessarily do the expanded body.
2. Different placement levels
Silica gel is suitable for people with thick skin on the bridge of the nose. It needs to be placed in a deeper layer for fixation. The puff has little requirement on the skin on the bridge of the nose. Silica gel is more suitable for people than silica gel.
3. Different disinfection methods
The expansion operation needs to be soaked and sterilized, and the degree of sterilization is more strict than silica gel. During the operation, strict aseptic operation is required to prevent the occurrence of infection during the expansion operation. The silica gel disinfection procedure is simpler than the expansion, and the requirements for the operation room are slightly lower than the expansion.
4. Different fixation effect
The stability of the expanded body is greater than that of silica gel, and there will be no shaking, sliding, light transmission and other phenomena of silica gel. In the real hand feeling, puffy body is better than silica gel.
5. Different long-term effects
Because of the compressibility of the material, the swelling is more suitable than silica gel. There will be no visual "stiff fake nose" and so on. Swelling is a kind of prosthesis which is closest to human body. Whether it is vision, carrying or touching, it is the same as the real bridge of nose.
