Abstract: PURPOSE: The design and harvest of radial forearm (RF) flap was modified with kiss flap technique in order to achieve the aim that skin-graft in donor site was not necessarily performed. Methods: The shape of RF flap was designed as two components of kiss flaps like flying wings. The long axis of the two components formed a V shape, and the surrounding retained tissues formed a V-Y geometry after the flap was harvested.The length and width of the components can be adjusted according to the size of the defects.Side-to-side stitching of the two components formed the final surface area to match recipient site and reconstruct the defect and the donor site was directly closed based on V-Y plasty. Results: Reassembling of the two components of RF kiss flap reached the same area of traditional radial forearm flap and the components survived well based on the cutaneous perforator vessels. The donor-site was directly closed without skin-grafting. Conclusions: Kiss design of RF is an ideal technique as donor-site can be directly closed with less donor-site morbidities,less scar formation and no skin-grafting.
