Objective To examine the eff ects of age, gender and bolus consistency in normal populations using the temporal measurement of Pharyngeal Transit Duration (PTD), which refl ects the duration of bolus fl ow from the ramus of the mandible to the upper esophageal sphincter. Method 40 normal and healthy subjects had Videofl uoroscopic Swallowing Examinations (VFSEs) of 5 ml thin and nectar thick liquids, and puree consistencies. A slow motion and frame by frame analysis was performed. Th reeway analysis of variance (ANOVA) was performed to examine the main eff ect and interactions, and paired t-tests for the three consistency comparisons. Results Older subjects had a significantly longer PTD than younger subjects (p<0.01). In addition, men had significantly shorter PTDs than women (p<0.01). Puree showed a significantly longer PTD than the other two consistencies, regardless of age and gender (p<0.05). Conclusion PTD is an indicative of motor weakness in pharyngeal swallowing secondary to aging. In addition, the results supported the assumption that there is a functional diff erence in pharyngeal swallowing between men and women. It is expected that the results of this study will be used for further investigation of patients with dysphagia.
