The advantage of the vascular anastomotic free flap is that any part of the body with a vascular supply of tissue is the donor area. It can be intercepted in relatively hidden places of the body, such as the abdomen, anterior femur or posterior lateral femur, etc., and the amount of tissue can be made larger or thinner, so its function is more able to meet the clinical needs. The disadvantage is that it requires more anatomical familiarity, skilled vascular anastomosis, and higher requirements for surgical operation. With vascular anastomosis of the free flap, the donor area is better hidden, can be in the thigh area or abdominal area to take skin, or take muscle, tissue, these parts are relatively hidden. In the summer, when the shoulders are bare, the traces can not be seen, with a part of the cosmetic function.
