Introduction of expanded nasal plastic materials
The expanded material for rhinoplasty is also called expanded polytetrafluoroethylene (hereinafter referred to as "expanded material"). It is an inert swelling polymer, and its interior is composed of many PTFE nodules. There are fine fibers interwoven in many directions between nodes, which have ultra-micro porous structure. These micropores allow tissue to grow, braking it and being accepted by the body's immune system.
Domestic puffed brand
First, stand up and show off.
The Li Xiu brand owned by Sokang in China has passed the certification of CFDA in China. The prosthesis has a special microporous structure, in which tissue cells and capillaries can grow to form tissue cohesion, which is as perfect as autologous tissue. After implantation, it is realistic and natural, and there are no surgical traces. It can also effectively prevent complications caused by light transmission, displacement and excessive tension of the prosthesis.
Introduction of Bulk Characteristics of Domestic Li Xiu
There are three kinds of facial plastic materials in Li Xiu: soft, reinforced and molded. Different sizes, the hardness of soft material is equivalent to that of dermis, and it is mainly used to fill facial soft tissue and deep wrinkles. The hardness of the reinforced material is close to that of cartilage, and it is mainly used for rhinoplasty, mandibular augmentation, zygomatic augmentation or contour repair. The molding materials mainly include willow-shaped rhinoplasty prosthesis, L-shaped rhinoplasty prosthesis, mandibular prosthesis, molded temporal prosthesis, molded zygomatic arch prosthesis and nasolabial groove filling material.
Second, Samui Debley
The registration certificate of Mesoude in China stipulates that Mesoude is suitable for filling nasal cavity, chin and temporal cavity, that is, rhinoplasty, chin augmentation and temporal augmentation. It is the only FEP (short for perfluoroethylene propylene) reinforced expanded polytetrafluoroethylene approved by CFDA in China, and all indexes reach or exceed those of similar products in the United States.
Introduction to the characteristics of domestic leavening agent
1, which is rich in FEP and has good biocompatibility, is called perfluoroethylene propylene, which is a material for cardiovascular repair and has excellent biocompatibility. FEP expanded PTFE material has better biocompatibility and physical processability than similar products.
2. The unique molding technology Mesud can provide a variety of molded and filled prostheses, which greatly facilitates the doctor's operation process, shortens the operation time and reduces the risk of postoperative infection.
3, simulation feel Because Mesud expanded products have good biocompatibility, materials and human tissues can be completely integrated, and almost no contact with implants after surgery, which has a first-class simulation feel.
Advantages of expanded rhinoplasty materials
1, less rejection, good biocompatibility, less rejection, light opacity, light weight, no obvious feeling of falling, and no compression and atrophy to bone tissue.
2. The advantages of good histocompatibility and more natural swelling are that the texture of the material is close to the human nasal tissue, and the histocompatibility is good, and the postoperative effect is generally more natural than that of silica gel. If the patient doesn't say it himself, no one will feel that he has had rhinoplasty.
3, good stability, non-sliding, its microporous structure allows microvessels to grow in, not easy to slide, and good stability. People with thin skin on the tip of the nose are also prone to rhinoplasty.
4, permanent retention effect rhinoplasty swelling can basically exist permanently in the body, of course, swelling has higher requirements for doctors.
Disadvantages of expanding rhinoplasty materials
1, it is difficult to take out the swollen substance because human tissue capillaries and human cells can easily invade the tiny pores of the swollen body and blend with the human body.
2, just finished the effect is slightly unnatural. Just after rhinoplasty, the nose of beauty lovers looks a little unnatural, because the swelling will be slightly reduced, but it will become more and more natural and beautiful after half a year.
3. The swelling material that is not conducive to supporting the nasal columella is soft, and the hardness is slightly poor when supporting the nasal columella and the tip of the nose.
4, the price is higher than silica gel. The price of expanding materials is relatively high, so the price of expanding rhinoplasty is generally twice that of silicone rhinoplasty.
It is inconvenient for doctors to shape the expanding material of rhinoplasty. Although it has some flexibility, its elasticity and three-dimensional effect are relatively poor. When carving, it is more difficult to carve, and the technical requirements for doctors are very high.
