Full-Thickness Skin Graft from the Submental Triangle for Facial Defect Reconstruction

Full-thickness skin grafting plays an important role in facial reconstruction for excessive skin defects or possible eye, nose, or lip distortion after a malignant tumor excision. For esthetic consideration, full-thickness skin grafts of the retroauricular region can be used, but the amount of skin is limited. The skin of the submental triangle has similar cutaneous features and provides a large graft. We aimed to evaluate the feasibility of using full-thickness skin grafts harvested from the submental triangle to reconstruct facial skin defects. We retrospectively analyzed 14 cases treated at a single institution to evaluate the clinical and esthetic outcomes, and patients' satisfaction. During 6-24 months of follow-up, the wounds healed with well-matched color, texture, and contour. No obvious hypertrophies or distortions were observed. Additionally, the removal of redundant submental triangle skin resulted in the secondary gain of double chin reduction. All patients were satisfied with the appearance of both donor and recipient sites. In conclusion, the submental triangle is a good possible option for full-thickness skin grafts used to resurface facial skin defects. Using this approach, both donor and recipient sites can achieve satisfactory esthetic outcomes.
