Studies of Diagnosis and Management of Swallowing Disorders

Abstract

The number of patients with dysphagia has been rapidly increasing with the rising number of senior citizens. For screening procedures, characteristic symptoms and swallowing sounds of dysphagia patients were clarified so that a new test series for swallowing disorders has been developed.
As for instrumental techniques, new measurements of videofluorography were demonstrated, including time analysis, residue places of the bolus, and shape and movement of the epiglottis. Furthermore, an acoustic analysis of the expiratory sound immediately after swallowing and new equipment using light-emitted diode (LED) have been developed.
For management, systemic and handy assessment was established in connection with management programs. A new swallowing maneuver was also developed. Food texture suitable for patients who need special care for eating has also been clarified.
For the future, new noninvasive diagnostic instruments and new management strategies will be necessary, besides studies on how to use parenteral intake together with oral intake.
