Background: The palatal augmentation prosthesis (PAP) is an intraoral prosthesis used in the treatment of dysphagia. Aim: The objective of the study is to examine the effect of PAP using tongue pressure and the Videofluoroscopic Dysphagia Scale (VDS) to understand the precise mechanism for improvement in swallowing function with PAP for oral cancer at retrospective survey. Methods and results: Fifteen patients were provided PAPs. Tongue pressure and VDS were evaluated with and without PAP. After intervention with PAP, tongue pressure significantly increased as compared to when without PAP (p <.05). The total mean VDS score with PAP was found to have significantly improved (p <.05). The mean VDS score of the oral phase also significantly improved with the PAP compared to without the PAP group (p <.05). Significant differences (p <.01) were found in each category, such as tongue to palate contact and pyriform sinus residue. Conclusion: PAP can improve tongue pressure, tongue to palate contact, and pyriform sinus residue.
