Reconstruction of lower lip with myomucosal advancement flap.

Background: In this article, a new surgical procedure that can be used for reconstruction of lower lip defects of any size is described.

Methods: In this prospective study, the surgical procedure was applied in 16 patients. In this procedure, the mucosa and the orbicularis oris muscle of the lower lip are repaired with a composite flap, and the skin defect is closed using local skin flaps. The patients were assessed in terms of complications, mouth opening, sphincter function of the mouth, and sensation in the lower lip.

Results: The aesthetic results obtained in all patients were satisfactory. Sufficient oral sphincter function was achieved in all patients.

Conclusion: Reconstruction of lower lip defects using the procedure described here can be performed in patients with lower lip defects of any size as long as the mucosal and skin repair lines are not superimposed. This procedure yielded good sphincter function and aesthetic results.
