The present study was designed to examine age and gender differences with respect to the duration of laryngeal closure, the onset of laryngeal closure in relation to the first cricopharyngeal opening, and the duration of cricopharyngeal opening for six different groups: normal younger men and women (22-29 years), normal middle-aged men and women (45-53 years), and normal older men and women (81-94 years) (10 subjects in each group for a total of 60 subjects). Data were collected by means of videofluoroscopic studies. During swallows of liquid barium, results indicated that normal older subjects had longer cricopharyngeal opening than younger subjects (P = 0.044). Results also revealed that the mean duration of laryngeal closure was significantly longer in women than in men (P = 0.013). The onset of laryngeal closure was significantly earlier in women than in men (P = 0.006). Also, bolus volume effects were observed for both the duration of laryngeal closure (P < 0.0001) and cricopharyngeal opening (P < 0.0001). During liquid barium swallows there was a linear increase in both the duration of laryngeal closure and cricopharyngeal opening.
