Hello, I want to know which of these two materials is better. The most important thing is to know the indications first. Silica gel material is inert and will not decompose in the body. Its advantages are good flexibility, easy to shape and carve, and it can be easily taken out completely even after many years. Its disadvantage is that its stability is slightly poor. The application of silicone nose prosthesis is the mainstream at present; The biggest advantage of swelling material is that it can fuse with its own tissue and has good stability, but its plasticity and flexibility are not as good as that of silicone, and it is expensive, so it is widely used in traumatic rhinoplasty.
