Nowadays, many plastic surgery institutions strongly advocate the expansion material rhinoplasty, but the expansion material (polytetrafluoroethylene Gore-Tex) rhinoplasty is really better than silicone material? We have made a systematic observation and comparison through a part of rhinoplasty patients, objectively make the following comparison. First, from the tissue compatibility of the two materials to compare. Inflatable materials and silicone prosthesis are better, high and low temperature resistance, chemical stability, corrosion resistance, tissue compatibility are good, non-toxic, non-cancerous, non-teratogenic. But there are very few people will have rejection of both, due to the special structure of the material, blood vessels and nerves can gradually grow into the interior of the bulge, so that the bulge and human tissue grow together, while silicone prosthesis is not and human tissue grow together, implanted in the body, the local may be a mild one-time inflammatory reaction, the late formation of a thin layer of fiber around the capsule, is currently the most used in rhinoplasty, the It is one of the most used and effective materials in rhinoplasty. Second, the comparison of the two plasticity in surgery. Although the expansion material has a certain degree of flexibility, but the elasticity and three-dimensional sense is poor, not suitable for sculpting and shaping, used to support the nasal column, the tip of the nose effect is not good. Silicone prosthesis itself has the basic shape of the nose and can be sculpted at will on its basis. Silicone rubber can be prefabricated into a variety of shapes and models of nasal prosthesis with nasal tip, nasal wing, nasal column and so on. Flexibility and elasticity are better, and the three-dimensional sense is strong. Third, we found through the observation of a part of the patient. Inflatable material will lose its original flexibility and become very solid when there is tissue growing into it, which makes its appearance and feel lose its realism, making the nose look dull and unnatural. The silicone implant does not have such a problem, it will not change its shape over time, there will be no tissue growth, and there will be no change in feel. And toughness and elasticity is more stable, so very natural. Fourth, because the expansion material will have the characteristics of tissue growth into. So this brings trouble to the patient’s secondary surgery, through the observation we found that the longer the bentonite material in the body, the more detrimental to the removal of the bentonite material. Due to the growth of tissue into the body, bulging and human tissue combined tightly, the formation of the cavity is becoming smaller and smaller, so if you take out the bulging material is like taking out a piece of their own tissue, the damage to the surrounding tissue is self-evident. Silicone prosthesis in the body does not exist in the tissue growing together in the trouble, the general surgery into the cavity of the prosthesis will not change much, the prosthesis in the body is like wearing a piece of clothing wrapped in a layer of fiber capsule, so take out the silicone prosthesis is as simple as taking something out of the pocket, will not produce any damage to the surrounding tissue. Fifth, the cost of tumescent material is generally about two times the cost of silicone materials. But the price of surgery is equivalent to 7 to 10 times the silicone material, so that is why the expansion has been strongly promoted by some plastic surgery institutions.
