PURPOSE: This paper presents surgical techniques for reconstruction of the cheek, oral commissure and vermillion in the repair of full-thickness cheek defects after resection of buccal-mucosal squamous cell carcinoma. PATIENTS AND METHODS: Four reconstructions in one-stage surgery with either a free radial forearm flap or a rectus abdominis musculocutaneous flap for cheek and oral commissure were carried out. There were combined with a new approach for vermillion advancement flaps. Most challenging was the need not only for morphological reconstruction of the orifice, but also for physiological reestablishment of sphincteric and sensory functions in the vermillion. RESULTS: Morphological and physiological reconstruction of the lip with sphincteric and sensory functions was attained. CONCLUSION: This valuable reconstruction technique was demonstrated in large, full thickness defects involving the cheek, oral commissure and vermilion.
