Surgical implant materials generally include autologous tissues and artificial materials. 1. Autologous tissue: usually includes dermal fat, fascia and bone. The advantage of autologous tissue is that there is no rejection reaction. The disadvantages are limited access to materials, increased new trauma, and poor plasticity. It is generally believed that for the absorption of autologous tissue, fat has the highest absorption rate, followed by dermis, fascia, bone and cartilage. 2. Artificial materials: Generally speaking, there are many kinds of artificial materials, such as metal, silicon sponge, silicone, PTFE, carbon fiber. However, these materials are less biocompatible and therefore have a higher incidence of displacement, rejection and infection after implantation. Therefore, patients should choose the appropriate implant material according to their own situation. If discomfort occurs, it is recommended to seek medical attention promptly to avoid delay.
