The versatility of the reverse superior labial artery flap

The reverse superior labial artery flap was introduced in 2015 as a reconstructive option for medial cheek defects. Notably, this flap can be redesigned as a more effective repair tool for large facial defect reconstruction. In this study, we redesigned the reverse superior labial artery flap to include the vascular territories of the infraorbital and transverse facial arteries in larger sizes for the repair of large facial defects. A reverse superior labial artery flap was used to repair large facial defects in 17 patients with a mean age of 74 years. The defects were located in the orbital region and entirely nasal sidewall in patient two, buccal region in patient three, and in lower lip and malar areas in patient five. The flap sizes ranged from 3.5 × 10 to 7 × 15 cm. A sensory examination was performed on the flaps at 6 and 12 months postoperatively. The mean follow-up period was 12 months. All flaps survived without partial or total loss. In a small number of flaps minor complications such as venous congestion, epidermolysis, and dehiscence were seen. No functional disability was observed in the lower eyelid or lower lip, and the esthetic appearance was evaluated as satisfactory by the patients. In all the flaps, the protective sensation was recovered in the postoperative 12th month. The reverse superior labial artery flap has an extensive arc of rotation, a reliable vascular pedicle, and a large cutaneous paddle. Therefore, this flap may be a versatile surgical repair tool for large cheek defects.
