(A) The remaining nasal mucosa was used to create a new upper layer for the palate. The buccal fat pad is dissected. (B) The buccal fat pad was flattened and spread under the new sinus floor mucosa. (C) A mucosal flap was harvested from the cheek above the level of the Stensen's duct to form the oral roof mucosa. Transfixing sutures ensure the good contact between the three layers. (D) Final external aspect with the tumor that has been removed. (E) Continuous sutures ensure a good contact of the oral cavity roof mucosa (picture taken 3 days after the surgery).
