Before rhinoplasty, the doctor will ask you what kind of rhinoplasty material to choose. Silicone prosthesis is the most used material, but now many plastic surgery institutions promote the expansion of the material rhinoplasty, expansion material rhinoplasty is really better than silicone material? We made the following comparison objectively through systematic observation of some rhinoplasty candidates. Histocompatibility comparison: bulging materials and silicone prosthesis are better, high and low temperature resistance, chemical stability, corrosion resistance, good tissue compatibility, non-toxic, non-cancerous, non-teratogenic, but there are very few people will produce rejection. Due to the special structure of the expanded material, blood vessels and nerves can gradually grow into the inside of the expanded body, so that the expanded body and human tissue grow together. Silicone prosthesis can not grow together with human tissue, implanted in the body, the local may be a mild one-time inflammatory reaction, and later formed a thin layer of fiber around its capsule. Shape comparison: 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, nasal tip effect is not good. Silicone prosthesis itself has the basic shape of the nose, can be sculpted at will on its basis, prefabricated into a variety of shapes and models of nasal prosthesis with nasal tip, nasal wing, nasal column, commonly used are “L” shape, “T” shape and willow leaf shape, flexibility and elasticity is better. Strong sense of three-dimensional. Comparison of realism: the expansion material in the case of organic tissue growth into the original flexibility will be lost, becoming very solid, which makes its appearance and feel lost realism, the nose appears more unnatural. Silicone implants do not have such problems, they do not change shape over time, there is no tissue growth and no change in feel, and the toughness and elasticity are more stable, so they are very natural. Comparison of the difficulty of the second surgery to remove: As the bentonite material will have the characteristics of tissue growth into, so the second surgery to the candidate brings difficulties, through the observation found that the longer the bentonite material in the body, the more detrimental to the removal of 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 with the disadvantages of tissue growth together, the general surgery into the cavity of the prosthesis will not change much, the prosthesis in the body is like wearing a dress as wrapped by a layer of fiber capsule, so remove the silicone prosthesis can be removed intact, will not cause damage to the surrounding tissue.
