We have briefly introduced the basic aesthetic criteria of the nose, and we believe that you are aware of the importance of having a fine and beautiful nose. So how are the roots and dorsum of the nose, which are so desirable, “made” by a skilled plastic surgeon? What are the mysterious things that fill the nose? Today, we will make a small introduction to the materials used in rhinoplasty surgery, which is of great concern to all of us. One of the most important things to consider before undergoing rhinoplasty is the type of filler material to be used. It is no exaggeration to say that choosing a suitable prosthetic material for you is crucial to the safety, aesthetics and durability in the later stages. Currently, there are two main types of implant materials commonly used in major plastic surgery hospitals: silicone and expanded body. So what is the difference between these two materials, and listen to us for you one by one. 1, directly put in the safety? At present, we widely used artificial materials, are long-term into the human body tissue, will not cause chemical changes inert material, their physical and chemical properties are stable, and not easy to cause immune reactions. China’s CFDA approved the use of prosthesis, have passed the national safety monitoring, so the safety of the prosthesis is more assured. 2.What about the effect? After completing a rhinoplasty surgery, the most concerned about is how the postoperative effect. Silicone and expandable body are two kinds of materials that have their own characteristics in terms of postoperative effect. Silicone gel prosthesis has good elasticity, very three-dimensional, its plasticity is strong, can be carved and shaped arbitrarily, but after the operation is not fused with the tissue, the feel and the real tissue will have a certain gap. Expanded material has a certain degree of flexibility, elasticity and three-dimensionality is slightly inferior to silicone, but because of good tissue compatibility, can group their own tissues closely, so the feel is very realistic. 3.If I want to take it out, can I do it? After rhinoplasty, due to various reasons, we may face the problem of removing the prosthesis. When it comes to removing the prosthesis after implantation, the main thing to consider is the compatibility and stability of the prosthesis. Silicone gel prosthesis is composed of silicone molecules, and after implantation in the nose, there is a tissue rejection reaction, and a fibrous envelope will be formed, which can not be well integrated with the tissue. However, if you want to take out the silicone gel prosthesis, you can separate the prosthesis from the surrounding tissues more easily according to the envelope. Expanded body, the composition of which is PTFE, will not form a membrane after implantation, because of its extremely small pores, so that the surrounding blood vessels and nerve tissue can gradually grow into the expanded body inside the prosthesis, tightly combined, very stable. However, this characteristic also makes it difficult to take out the expanded body after implantation for a period of time. 4.Price how to? Generally speaking, the price of expandable prosthesis is slightly higher than that of silicone prosthesis, and the carving and implantation are also more difficult, thus the requirements for plastic surgeons are also higher.
