Silicone and bentonite are the two most clinically used polymer chemical materials, and are also the safest and most stable nasal filler materials, which can provide strong support, good retention, suitable toughness, friendly interface, and long-lasting effect, which is incomparable to any injectable materials and linear sculpture materials. There is no denying that nasal prosthesis has problems such as light transmission, localized thinning of the skin after long-term placement and overly delicate skin, and that is why the development of tumescent materials. The greatest benefit of the expanded material is the “permeable” relationship with the periosteum of the implant. Because of the porous structure of the expanded material, human tissue cells can gradually grow into the gap, to achieve a more solid fixation effect; and because of the tissue “penetration-like” growth into the material, the equivalent of making the skin thicker and more solid, so greatly reducing the “translucency phenomenon “The skin on the surface of the prosthesis is more natural; also because of this infiltration effect, the prosthesis is very solid and not easy to shake, which is another advantage. However, there are two sides to everything, and the shortcomings of the expanded material are also very obvious. One is the problem of infection, the infection rate of expanded body is relatively higher than that of silicone, which may be related to the production process, or may be related to the susceptibility to infection of the material itself, or may be related to the operation of the doctor; the other is the difficulty of removing and the problem of side damage, once the infection must be removed. However, due to the osmotic-like effect mentioned above, the surrounding tissues have grown into the material, so it is very difficult to remove it, and it is easy to tear and damage the soft tissues of the nose itself, so it is very difficult to look at the nose after removing the bentonite. Therefore, for different nasal conditions, the best option is to choose the most suitable prosthesis by the doctor and the patient.
