Before facial fillers can be performed to improve the shape of the face, the filler material must be selected first. Because not only the facial contour and shape should be considered, the texture is also crucial, such as the forehead should be bony (hard texture), the cheeks should be soft (soft texture), and the temporal area should be in between the first two. In addition, the stability of the postoperative period should be considered. Thus, reasonable selection of filling materials is a prerequisite for successful surgery. At present, the materials commonly used for facial filling are: 1, synthetic molding materials: silicone, expanded polytetrafluoroethylene (referred to as tumescent) 2, autologous materials: autologous fat 3, injectable filler materials: Abelef (non-absorbable, permanent), hyaluronic acid and colloidal materials (absorbable, temporary). 4, of course, there are other unlisted materials available. However, the most commonly used now is autologous fat and tumescent. For forehead and temporal fillers, it is better to choose harder filler materials due to the need for texture, so the flexible material of tumescent is the ideal choice. It can be implanted through a small incision in the hairline, and has good tissue compatibility and is very stable after implantation, and can be surgically removed if you are not satisfied with the results after surgery. If you choose autologous fat injection grafting to fill the frontal temporal area, the texture is a bit “facial”. For cheek filler, due to the texture requirements, it is best to choose autologous fat tissue injection grafting, which can be well activated and become one in the cheek area after injection grafting, with no difference in form and texture and permanent. In the past, silicone material was often chosen to fill the forehead and temporal area, but it is rarely used due to the poor compliance of the hard material, the need for large incisions for implantation during surgery, and the poor tissue compatibility, and the easy formation of fluid around the material after surgery, which affects the surgical effect.
