The contour of the face is composed of both bony structures and soft tissues. If there is too little local soft tissue, the face will appear bony and sunken, requiring facial filler plastic surgery. Temporal area and cheek are common areas of facial depression. Currently, injectable fillers are more commonly used, either artificial materials such as hyaluronic acid or your own fat. The advantages of using one’s own fat are that it is easy to get the material, inexpensive and beautiful, and there is no rejection of the autologous tissue, but because of the high absorption rate after fat transplantation, only about 40% of the fat can survive, and it needs to be filled several times, in addition, the particles of autologous fat are coarse and easy to be uneven without excellent technique.
