Limited defects in the oral cavity can be treated with local and pedicled cheek flaps. It allows to preserve the functions of the resected organ. Large defects in the midline of the hard palate can be reconstructed with double opposing myomucosal cheek flaps. The aim of this study was to discuss the methodology of the flap harvest and to show our experiences of treatment in a group of 15 patients with oral cavity cancer. In 1 patient the double opposing myomucosal cheek flap was harvested due to the wider local defect. The small size of the flap with ability to use the double opposing cheek flap in more extended defects as well as short duration of the surgery procedure can lead to reduced risk of postoperative complications. Finally, cheek flaps form an effective method of treatment of defects in the oral cavity.
