RESUMO
<p><b>OBJECTIVE</b>To introduce a new method for enlarging the survival area of an expanded flap.</p><p><b>METHODS</b>After the skin expander was inflated with enough injection, the first delaying was performed. In the operation, two incisions were made in the skin and subcutaneous tissue superficial to the expander capsule on both sides of the long axis of the expanded flap. After 10 to 14 days, the second delaying followed, in which one pedicle was divided to form a unilateral-pedicled, super-long random flap. When the flap was transferred to the recipient Since 2000,this technique has been used in 16 patients. All the area, the door site was closed directly.</p><p><b>RESULTS</b>flaps survived completely.</p><p><b>CONCLUSIONS</b>The technique of twice delaying can enlarge the survival area of the expanded skin flap.</p>
