Surgical planning. The technique is based on the shape of two trapezium flaps, 12 mm in width and 10 mm in length each, interconnecting at the narrow base. The narrow base of each flap measures half of the width. Each flap is marked equatorially across the midline with opposite cut-outs and included in the midline resection The blood supply entering the flap is ensured over the non-dissected half distance of the wider base (6 mm), thus not exceeding the generally accepted length-to-width ratio of 1:2 for random-pattern flaps.
