Figure 2. Surgical technique for the medially based de-epithelialized flap. (A and B): A circumferential incision along the nostril sill and alar base freed the alar base from the upper lip. At the columellar base, fresh epithelium was shaved on the medial side of the incision line. The widened scar on the upper lip was excised. (C and D): The raw (denuded and de-epithelialized) tip of the columellar base was pulled under the medial tip of the alar base flap and sutured tightly. (A and C): frontal view; (B and D): worm's eye view
