Purpose: A 53-year-old institutionalized male patient with a history of postoperative bilateral hypoglossal nerve injury was admitted for treatment of dysphagia. He experienced dysphagia involving oral cavity-to-pharynx bolus transportation because of restricted tongue movement and was treated with a palatal augmentation prosthesis (PAP), which resulted in improved bolus transportation, pharyngeal swallowing pressure, and clearance of oral and pharyngeal residue. The mean pharyngeal swallowing pressure at tongue base with the PAP (145.5±7.5mmHg) was significantly greater than that observed immediately after removal of the PAP (118.3±10.1mmHg; p<0.05; independent t-test). Dysphagia rehabilitation with the PAP was continued. Approximately 1 month after PAP application, the patient could orally consume three meals, with the exception of foods particularly difficult to swallow. Discussion: The supporting contact between the tongue and palate enabled by the PAP resulted in improvement of bolus transportation, which is the most important effect of a PAP. The increase in pharyngeal swallowing pressure at the tongue base because of PAPenabled tongue–palate contact might play an important role in this improvement. Since a PAP augments the volume of the palate, it enables easy contact between the tongue and palate, resulting in the formation of an anchor point for tongue movement during swallowing. Thus, application of a PAP increases the tongue force, especially that of the basal tongue. Conclusion: A palatal augmentation prosthesis helps improve pharyngeal swallowing pressure at the basal tongue region and might contribute to the decrease of oral as well as pharyngeal residue.
