Expanded body is also called polytetrafluoroethylene, which is also translated as Gautex. It is made of inert and soft materials, expanded polytetrafluoroethylene (PTFE) and hard polyethylene. The former can produce microporous structure after expansion, and the gaps between micropores allow tissues to grow inward, and tissues, cells and blood vessels of the body can grow into them to form tissue connections, which are as perfect as autologous tissues. Swelling can also be removed or corrected at will. Compared with other hard and thick rhinoplasty materials, the swelling material is softer, more compliant and the postoperative effect is more harmonious and natural.
The expanded rhinoplasty material has good compatibility with human body, is non-toxic, non-carcinogenic and non-allergenic, and does not need to be replaced for life. Moreover, the texture and feel of the material are very close to normal nasal tissue. After augmentation rhinoplasty, it is beautiful and natural, integrates with nasal tissue, does not move or deform, and it is even more impossible to pierce the skin, and has no sense of permeability of silicone. It is generally difficult to find artificial marks after surgery.
Although the expanding material plays an important role in rhinoplasty, it is not suitable to pad the tip of nose. Because the skin at the tip of the nose is thin, if the tip of the nose is swollen, the skin at the tip of the nose may turn red because of swelling, which is easy to cause infection. Moreover, although the expanded material has a certain softness, it will still appear stiff and unnatural when used to cushion the tip of the nose. Therefore, the best material to pad the tip of nose is autologous cartilage or artificial skin flap for rhinoplasty in Korea.
Experts remind that rhinoplasty has a specialty. When seeking beauty, you must have a general understanding of rhinoplasty materials, so that you can choose the appropriate rhinoplasty materials according to your personal situation at the doctor's suggestion.
