Background:. Problems with poor circulation often occur when a large defect or a distant region, such as the apex of the nose, is covered with a paramedian forehead flap. Delay technique increases the safety of reconstruction procedures, but it has been used less frequently because a 2-stage surgery is necessary, and various other flaps and techniques have been developed. Method:. We performed the delay technique of paramedian forehead flap at the same time as tumor resection. For the flap, a narrow pedicle of about 1-cm was prepared on the supratrochlear artery and vein, and the incision was extended toward the lateral side conforming to the defect morphology, and a paramedian forehead flap with a design consistent with the esthetic unit containing the defect was prepared. The region below the flap was dissected to create the flap bipedicle, and surgery was completed. Result:. This procedure was used in 4 patients with malignant tumor of the external nose, and the flap survived perfectly in all patients. The postoperative esthetic outcome was also found to be good. Conclusions:. This procedure does not increase the frequency of surgery, circulation in the flap is maintained, the flap pedicle on the supratrochlear artery can be made narrow, and flap thinning can be performed from the beginning. Coverage of an extensive defect is possible because a large flap can be excised, and satisfactory esthetic appearance can be obtained by matching with the esthetic unit. The delay technique for various flaps (not limited to forehead flap alone) should be considered an effective technique for the current treatment of malignant tumors.
