The flap has a semi-spindle shape that extends from the angle of the mouth to the defect with a maximum transverse diameter of 16 mm (Fig. 4a). The buccinator was identified and elevated until the defect could be closed using 5-0 vicryl sutures (Fig. 4b and c).
After 6 months of follow-up, no evidence of recurrence was observed.
