Overview of the Pang Flap: Design, Technique, and Clinical Uses

The talk presents the Pang flap, also called an anchor flap or bilateral advancement rotation flap, as a versatile single-stage reconstructive option, especially for nasal defects. The speaker explains why it is favored: it uses adjacent skin for a good color and texture match, hides scars in cosmetic junctions, combines advancement and rotation to preserve or restore nasal convexity, minimizes tip or alar distortion through symmetric movement, and has a wide base with short arms for reliable healing and low complication rates. Compared with secondary intention, bilobe/trilobe flaps, bilateral advancement or transposition flaps, dorsal nasal rotation, and multistage repairs, it often provides faster healing, better contour restoration, less pin cushioning, less undermining, and fewer stages. The flap’s evolution is reviewed from early descriptions to later modifications that shift the design laterally and distally, widen the base, improve cheek advancement, and place scars in subunit junctions. Practical technique emphasizes starting at the defect’s distal point, extending laterally into the alar grooves and nasal facial sulcus, carefully preserving blood supply, undermining in the submuscular plane, and inseting the leading edge alternately on each side before excising standing cones. The speaker notes cautions for small or tight noses, dorsal humps, and excessive tension, and discusses common postoperative issues like bruising, swelling, and occasional need for dermabrasion. Although most useful for nasal tip and supratip defects, the flap can also be applied to the scalp, philtrum, and proximal nasal dorsum, with examples showing good contour preservation and high patient satisfaction.
