Lip reconstruction remains a challenge because of the high specifications for functional performance and acceptable cosmesis. The technique used depends on the size, location, and depth of the defect. Primary closure and wedge resection can be used for smaller defects on the upper and lower lip, respectively. The Abbe flap can be used for intermediate-sized, full thickness defects located in the central and lateral subunits of the upper lip. A radial forearm free flap can used for subtotal upper lip defects, whereas near total lower lip defects benefit from the use of Karapandzic flap. The Estlander flap is reserved for intermediate-sized lower lip defects involving the oral commissure. Special attention must be paid to vermillion reconstruction as even small defects may be noticed by the casual observer. The vermilion advancement flap and the vermilion switch flap are two flaps typically used for larger defects involving the vermilion.
