Reconstruction of a subtotal upper lip defect with a facial artery musculomucosal flap, kite flap, and radial forearm free flap: a case report

For reconstructive surgeons, massive midface defects, including large, full-thickness wounds on the upper lip, can be very challenging. Although there are many methods for reconstruction of upper lip defects, it is difficult to obtain satisfactory restoration of oral functions and good cosmetic results. This case report presents a man with massive midface defects, including upper lip, left nose, and cheek defects. Over the previous 2 years, the patient had three reconstructions with sequential free flaps for the resection of recurrent tumors, the first of which was in March of 2016; this resulted in the patient having massive midface defects, including an upper lip defect, a defect on the left side of the nose, and one on the left cheek. The defects were reconstructed using a radial forearm free flap (RFFF), a facial artery musculomucosal (FAMM) flap, and a kite flap. In June 2016, he underwent a second reconstruction, this time of the left nose defect, using a left anterolateral thigh (ALT) flap. In March of 2017, the patient underwent a third reconstruction with the use of a free ALT on the left intraoral cheek and the defects on the neck. All flaps survived. No complications were encountered postoperatively. The patient regained good oral sphincter function with no reports of drooling. Although the patient underwent three surgeries, the reconstruction results were acceptable. For massive midface defects, including large, full-thickness wounds on the upper lip, the combination of a FAMM flap, kite flap, and RFFF promotes the reconstruction of the complex midface structure and improves the resulting functionality.
