Three-dimensional reconstruction of the anterior mouth floor and ventral tongue after ablative surgery can be achieved using several techniques. The ideal reconstruction should be accomplished with the same or similar type of tissue, and cheek axial myomucosal flaps based on the branches of facial or internal maxillary arteries seem ideal for this purpose. From March 2005 to May 2007, 23 patients underwent cheek axial myomucosal flap reconstruction after oral cancer surgical ablation. Thanks to their thinness and pliability, these flaps were frequently shaped to obtain an accurate reconstruction. According to Whetzel's hypothesis, an intraoral flap designed to include the axial vessel of one area can safely carry the mucosa of a neighbouring vascular area. The authors describe a large buccinator myomucosal island flap based on the branches of the facial artery and formed in a trilobed shape in order to capture the adjacent buccal mucosal angiosome from the internal maxillary artery. The flap provided the correct anatomical oral reconstruction for the anterior mouth floor and ventral tongue. The function of the tongue, oral intake and mastication were not impaired. The trilobed buccinator myomucosal island flap is a suitable option for the three-dimensional reconstruction of the anterior mouth floor and ventral tongue.
