Result: In 33 composite flaps used, flap width to thigh circumference less than 20% in 27 cases (81.8%), more than 20% in 6 cases (18.20%); There were 28 cases in which the donor site was directly closed, 5 cases required skin graft; All direct closed cases had flap width / thigh circumference index below 20%; On the contrary, in cases having this index greater than 20%, the donor site required skin graft with p < 0.01.
