A new flap design for reconstruction of full-thickness defects of the lower lip: The extended upper lip island (EULI) flap

SummaryThe extended upper lip island (EULI) flap has two advantages. It provides a wide mucosal surface, like that of the facial artery musculomucosal flap and does not leave a pedicle across the mouth. Aesthetic results with the EULI flap are almost as good as those with the cross-lip flap. An 89-year-old woman presented with squamous cell carcinoma of the lower oral vestibule. Full-thickness lower lip resection and marginal mandibulectomy, including resection of the surrounding gingiva and mucosa, were performed. The defect was reconstructed with an EULI flap that included the facial artery and vein. There were no severe postoperative complications, but two mild complications did occur: mild congestion of the distal end of the skin paddle and mucosa for two days after surgery and partial paralysis of the orbicularis oris and levator anguli oris muscles. The EULI flap is useful for extended lower lip reconstruction.
