Upper-lip reconstruction using a free dorsalis pedis flap incorporating the extensor hallucis and digitorum brevis muscles.

The combined dorsalis pedis cutaneous, extensor hallucis and digitorum brevis muscle conjoined free flap is useful for a moderate or subtotal defect of the full-thickness lip when local or regional flaps are not applicable. This method can restore good oral competence, adequate oral aperture allowing dental hygiene, and an ability to purse the lips and create a seal.
