Videofluoroscopic identification of two types of swallowing.
Two forms of swallowing were observed during videofluoroscopy in 166 asymptomatic patients, consisting of an air-containing ("open") pharynx in 120 (72%) and an occluded ("closed") pharynx in 46 (28%). The epiglottis inverted differently in the two forms of swallowing.
