The incidence of multiple swallows for liquid and paste, and the time delay between multiple swallows, was determined from
videofluoroscopic records of modified barium swallow tests. In a comparison of liquid and paste, the overall incidence of
multiple swallows did not differ, for either patients with head and neck cancer or normal controls. However, for liquid swallows
the incidence in patients with cancer was abnormally high, predominantly in patients with pharyngeal cancer.
