Bilateral reverse Yu flap for upper lip reconstruction after oncologic resection

摘要

A 79-year-old man was referred to our department for surgical treatment of a biopsy-proven Merkel cell carcinoma on his upper lip. Wide tumor excision was performed. The resulting full-thickness inverted heart-shaped defect measured 4 cm in the transverse axis and involved almost two-thirds of the upper lip (Figure 1).
