The Abbe flap is most commonly used to repair full-thickness defects of the lip that do not involve the commissure. This well-perfused axial flap is based on the labial branches of the facial artery. The inferior labial vessels have been shown to support a cutaneous territory, including the entire lower lip, chin, and submental skin. Defects extending beyond the confines of the upper lip may be reconstructed with an extended lip switch flap that is based on the inferior labial artery. This "extended" Abbe flap allows functional and cosmetically acceptable repair of the upper lip, medial cheek, columella, and nasal sill. Case presentations illustrate the technique and outcome.
