Outline of Final Research Achievements

Pharyngeal residue is severe finding for dysphagia patients, because it may cause aspiration after swallow. Swallowing cannot be observed outside．For dysphaiga rehabilitation, imaging evaluation is indispensable to understand the pathophysiology of pharyngeal residue or aspiration by detail, to execute accurate kinematic analysis, and to provide the appropriate intervention based on the evaluation. In this study we combined the evaluation of swallowing CT as a kinematic analysis and the evaluation of high resolution manometry as kinetic analysis for understanding the pharyngeal residue. Kinematic and kinetic analysis provided the better understanding the cause of pharyngeal residue and selection of swallowing maneuvers more effectively. The results confirmed the significance of treatment oriented evaluation for each dysphgic patients.
