One-stage reconstruction of a large defect of the lower lip and oral commissure

In each case, the reconstructed lower lip could maintain adequate elevation of oral the commissure using the temporal muscle was worked. The first case which used a local flap externally could avoid sialorrhea and had good sensation, and could close the mouth firmly soon after surgery. The appearance was acceptable. In the other case, leakage of oral contact and air occurred at the oral commissure because of the thickness of the forearm flap but improved after minor correction some 8 months after the surgery.
