| Abstract;The purpose of this study was to quantify the changes in the swallowing function that occur as a result of the aging process itself. Videofluoroscopic examinations of oropharyngeal swallowing, 3 bolus volumes (1,5,10 ml), were performed by six men over the age of 85 years and by six men under the age of 60 years. None of the subjects had any present or past history related to swallowing problems. Data analysis compared 1) abnormal findings (premature spillage, laryngeal penetration and aspiration); 2) temporal relationships of oropharyngeal events; and 3) biomechanical computer analysis of swallowing events. As bolus volume increased, an increase was observed in the frequency of premature spillage and laryngeal penetration in the aged. The distance of the laryngeal movement during swallowing was significantly longer in the aged than in the controls. However, the degree of the laryngeal elevation at the oral onset was significantly higher in the aged than in the controls, so that the range of laryngeal elevation during the pharyngeal swallow was not different between the two groups. The %LE (P) at the time the bolus arrived at the pyriform sinus was significantly lower in the aged than in the controls. On the other hand, the range of auterior laryngeal movement and the width of the cricopharyngeal opening as the bolus volume increased were significantly higher in the controls. These exhibited the same degree in the aged. We concluded that normal aging dose not affect the overall efficiency of oropharyngeal swallowing. However, pharyngeal delay, and a small capacity in the range of laryngeal motion and cricopharyngeal flexibility were present with normal aging, and these changes might be contributing factors in the development of potential aspiration and swallowing disturbances in the elderly.
