Abstract
The authors describe the anatomic aspects and surgical technique of the depressor anguli oris musculocutaneous flap for reconstruction of the upper and lower lips. Twenty patients were submitted to surgical treatment, 19 for carcinoma and for upper lip scar deformity. In all patients the repair was performed with the depressor anguli oris musculocutaneous island flap. At the follow-up, lip function was satisfactory in 19 patients and unsatisfactory in 1 patient. The aesthetic results were considered satisfactory in all patients. The depressor anguli oris musculocutaneous island flap is safe for upper and lower lip reconstruction, with good functional and aesthetic results, and can be added as a new flap for lip reconstruction.
