Both have their own characteristics. As far as the material itself is concerned, silica gel is superior to the block in maintaining the carved shape, and can quickly recover to its original state after removing the external force that denatures it. Swelling is characterized by micropores and soft texture. Micropores are beneficial to the growth of microvessels and small nerves and are firmly combined with their own tissues. In case the implanted prosthesis needs to be taken out, the silicone prosthesis is easier to take out with less local damage. Whether the effect of rhinoplasty is natural or not mainly depends on the aesthetics of both doctors and patients, the technique of carving prosthesis by surgeons and the technique of separating implant cavities.
