Reconstruction of the lower lip defect using a tongue flap after excision of verrucous carcinoma

A 64 year old man came to us with and irregularly 4.2×1.5cm sized warty lesion which had been existed for about ten years in the vermillion border of his lower lip. The biopsy-proved diagnosis was verrucous carcinoma. Deep lip shave was performed with a 5mm safe margin, and a small amount of orbicularis oris muscle was included and resulted in a defect of almost four fifths of the entire lower lip vermillion. The flap from the end of the tongue was reflected dorsally and mobilized into the area of the full thickness defect of the lower lip under general anesthesia. After 15days, the tongue flap was cut and insetted after trimming for the reconstruction of the defected vermillion border. The postoperative result was very excellent in view of esthetic and function. For three years after surgery, there is no evidence of recurrence. We found that tongue flap can retain both a sufficient buccal cavity and the contour of vermillion border, and it is a very useful alternative to other local flaps for the vermilion defect.
