[ 11 ] - Submental Artery Island Flap in Reconstruction of Harde Plate after wide Surgical Resection of Veruccous Carcinoma. Two case reports

Introduction: Reconstruction of intraoral soft tissue defects is important in restoring function and esthetic. In large defects, there will be demand for regional pedicle flaps or free flaps. Hard palate separates nasal and oral cavities. Due to the small surface area between flap and remaining palate after surgical resections, optimal blood supply of the flaps for hard palate reconstructions ...
