Submental flap reconstruction of perioral electrical burn defects: A case report

Abstract

Electrical burns involving the perioral region are uncommon but often lead to full-thickness soft tissue loss, impairing both function and aesthetics. Optimal reconstructive strategy selection is pivotal, particularly challenging in settings without microsurgical resources. The submental flap provides a reliable, well-vascularized tissue source with favorable color and texture match and a concealed donor-site scar. We present a case of a male patient who sustained a low-voltage electrical burn resulting in a perioral soft tissue defect, successfully reconstructed with a pedicled submental flap. At three months postoperatively, the flap remained fully viable, with preserved oral competence, satisfactory aesthetic appearance, and no donor-site morbidity. This case underscores the submental flap as a safe, technically straightforward, and effective option for small to moderate perioral defects caused by electrical injury.
