Expanded polytetrafluoroethylene (PTFE) is a safe subcutaneous implant, which is easy to shape, more realistic in rhinoplasty (compared with silica gel), better in histocompatibility and broad in application prospect.
Because of its good biocompatibility and unique microporous structure, it is non-toxic, non-carcinogenic and non-allergenic. Human tissue cells and blood vessels can grow into its micropores to form tissue connections, just like autologous tissue.
PTFE has two biggest advantages:
1. Soft texture and natural hand feeling after operation.
2. High histocompatibility and low rejection rate.
1. The expanded plastic material is composed of expanded PTFE columnar structure, which is connected by PTFE fibers arranged in all directions, balancing the strength of the expanded material in all directions.
2. The average length of internode fibers (such as pore size) is 20-25μm, and the unique micropore ultrastructure of expanded plastic material makes it have the characteristics of biomaterials-easy to bend, soft and not easy to wear. In addition, this ultrastructure also allows cell infiltration and tissue growth.
Therefore, bulk plastic materials are ideal filling materials for plastic surgery, but if you want good results, you need to go to a regular hospital to ensure the regularity of bulk plastic materials and the professionalism of bulk plastic surgery.
