Over the past twenty years, I don’t know how many rhinoplasties have been done, from the very first silicone rhinoplasty to puffy, to Medpor material, to autologous cartilage, autologous fat and hyaluronic acid rhinoplasty, these methods should be said to have their own advantages and disadvantages, it is difficult to say that a material has absolute advantages. Then there is a change in the point of view of rhinoplasty, in the past is simply to put a material to hold up the dorsum and tip of the nose, which led to many problems, such as unnatural nasal tip formation, the tip of the nose is broken by the tip of the prosthesis, etc.. Now the industry is unanimously more emphasis on comprehensive rhinoplasty, that is, not simply focus on the nose high, but also do beauty, which includes the nasal dorsum, nasal tip, nasal wing, nasal column, nostrils and other subunits of the shape. Today, we are talking about two materials: silicone and expanded body. According to the viewpoint of peers, silicone material is like particle board; while the expansion is the solid wood board. If your home renovation, want to lay a wooden floor, you will ask the same question: laminate good ah, or good solid wood ah? In terms of price, solid wood is much more expensive! But, solid wood is not much better than laminate? Not really. Solid wood flooring to prevent termites, to regular maintenance …. In the eyes of many people who live, solid wood flooring is synonymous with “cumbersome”. And more importantly: pave out the floor is not good, and pave the floor of people have a relationship with the material is not very relevant. You are to buy the world’s most expensive wood flooring, but to a two days before the village to repair the fence wall decoration guerrilla team, you think the effect will be? Therefore, the decorator is the most important, a good decorator can bring out the best of each material, to minimize and hide its shortcomings. A, silicone Advantages: cheap, good carving, good to take out. Disadvantages: after placement into the body, the organism will form an envelope around the silicone, which may slide and calcification may occur in the long run. A few people may have a thicker envelope. The formed silicone prosthesis is too thin and easy to appear contoured. The silicone prosthesis is relatively hard, and the root of the nose will follow the movement in the opposite direction when the tip is rubbed. In addition, some people with thin skin on the back of the nose may have a “translucent” feeling when exposed to strong light. Overall evaluation of silicone: cheap, safe and reliable. Second, tumescent advantages: good tissue compatibility, good to the organization that this is their own gang, can grow to the tumescent inside. The shape is very natural, natural to professional doctors are not easy to find. The tissue grows inward, making it almost impossible to shift the possibility of slippage. Disadvantages: there is a certain incidence of infection. The microstructure of the expanded material can be seen by electron microscopy, from which it can be seen that the microstructure of the expanded body is a forest-like mesh. These mesh voids are about 25 microns. Bacteria have an average diameter of 1 micron, and the main cells in the body to remove bacteria: macrophages have an average diameter of 50 microns. That is to say, bacteria to get into the puffy, as easy as a hand; and as the anti-infection macrophages want to enter to destroy bacteria, but as difficult as the sky. Therefore, once the bulge is infected, there is no possibility of recovery. 08 August of a professional journal, an American doctor published his review of 17 years of application of bulge in rhinoplasty, the average infection rate of 1.9%. That is, for every 100 people who use expansions, two will develop an infection. This is a bit like a solid wood floor termites – who falls on his head who is unlucky. The overall evaluation of the expansion: natural, safe and reliable. In clinical work, both materials are very commonly used, a good plastic surgeon will be familiar with the advantages and disadvantages of both, and targeted to overcome. For example, for the silicone prosthesis, translucent, can be covered with a layer of autologous dermis or artificial dermis on the surface of the prosthesis to increase the thickness of soft tissue; or later modified with autologous fat. And for the easy infection of the expansion body, the operation should pay strict attention to the disinfection of each link. Of course, the specific material used, or the owner (customer) to say.
