Abstract

There have been no substantial reports on the incidence of deglutition disorders at private ENT clinics in Japan. In this study, 81 subjects over the age of 75 years who visited Nishiyama ENT Clinic were examined for their deglutition functions. As the methods of examination, a speci-fically prepared questionnaire and videoendoscopy were selected. The subjects were classified into 3 groups: aspiration group (26), penetration group (21) and normal group (34). Weight loss over 2 kg within 1 year was noted in 7 cases within the aspiration group, 2 in the penetration group and 1 in the normal group. In those subjects who presented apparent misdeglutition, tactile sensation of the pharyngolaryngeal mucosa was deteriorated and effective cough ability was sup-pressed, and as a result the incidence of aspiration pneumonia increased. The findings suggest that aspiration pneumonia increases calorie consumption and leads to loss of body weight.
