The choice of rhinoplasty material has always been one of the most concerned about, now on this issue to give you a brief introduction. 1, silicone is a polymer synthetic material, its main component – silicon is the human body contains elements, so it is implanted in the human body, the nature of stability, very few rejection reaction, it is easy to carve, low price, there are two kinds of L-shape and willow leaf shape, there are a variety of specifications to choose from, is the most widely used nose chin prosthesis material. Silicone has domestic, imported and joint venture three kinds, domestic materials are also commonly used, imported materials can be relatively good. 2, expanded polytetrafluoroethylene carbon (PTFE) that is often referred to as bentonite, the advantages of non-allergic and immune rejection, low incidence of inflammation, the tissue can be to its growth, because of its soft and easy to bend, placed in the touch of the natural. This material is divided into domestic and imported, imported is the U.S. Gore company produces GORE-TEX, commonly used specifications 1.5cm * 6.5cm * 4.5mm, is currently the best placement of human prosthetic materials. In this special note a problem: expandable body are not all infected? Because the surface of the expanded body is microporous, the autologous tissue can grow into part of it, which is good for the fixation and appearance of the prosthesis. However, if the prosthesis is exposed outside the body for too long, bacteria can enter the micropores and increase the chance of infection of the surgery. Moreover, if the nose is oily and a deep anoma is formed, it can also be easily infected if it is connected to the prosthesis cavity. So how to deal with the expanded material is especially critical: First, you must be very familiar with the expanded body, the carving time should not be too long, we usually in about 10 to 15 minutes. Secondly, after carving, it should be put in sterilized water, not exposed to the air, then the sterilizing liquid will also enter the microporous, and play the purpose of preventing infection. Third, facial disinfection should be done more thoroughly, pay attention to the nostrils and facial grease, the whole procedure must be strictly aseptic. Fourth, before putting the prosthesis to the prosthesis cavity to do rinsing, usually with Qingda. Fifth, before removing the stitches after surgery and two or three days after removing the stitches, patients are required to pay strict attention to the waterproofing of the incision. These above do only one purpose, to avoid all possible infection may occur, if you can strictly do puffed body will not be infected. 3, autologous cartilage has been the most concerned about the problem, it is taken from their own rib cartilage or ear cartilage, by artificial sculpture molding. Because it is its own material, no rejection reaction after transplantation is especially suitable for simple nasal tip and nasal wing plastic surgery. However, it has the disadvantages of increasing a surgical site, part of the cartilage can be absorbed by the body after implantation, and it is easy to be deformed. Therefore, it is best used for the repair of defective nasal tip and nasal wing. Currently the hottest kind of nasal septum cartilage cushion tip surgery, is a very good operation, but encountered individual septum cartilage is very small, or to take other parts of the cartilage. 4, in fact, puffer and silicone have their own characteristics. 5, “allogeneic decellularized tissue patch” is taken from the human allogeneic dermal tissue through biological and chemical methods to remove a variety of possible rejection reaction of cells, and then compressed into a sheet. In fact, this material was available a long time ago, but has been rarely used in clinical practice, there is no harm to the human body has been reported. Because of its lower cost than bentonite, and to avoid the secondary trauma caused by taking cartilage, it has attracted a lot of attention, but its effect and absorption problems make people question.
