The swallowing patterns of four patients with oral cancer with intraoral palate reshaping/lowering protheses were studied with and without their prostheses 3 months postoperatively. The prostheses resulted in improved swallow efficiency, increased duration of tongue contact to the pharyngeal wall, and improved speed of movement of the bolus from the valleculae to the pyriform sinus. These results emphasize the effects of the tongue on the pharyngeal as well as oral stage of the swallow.
