Fig. 1 5- 1 2 Lateral projection with exposuremade at peak of laryngeal elevation.Hyoid bone (white arrow) is almost at levelof mandible. Pharynx (between large arrows)is completely distended with barium.

Fig. 1 5- 13 AP projection of the same patientas in Fig. 1 5- 1 2. Epiglottis divides bolusinto two streams, filling the piriform recessbelow. Barium can also be seen enteringupper esophagus.

Fig. 1 5- 1 4 AP projection of pharynx and upper esophagus with barium. A, Head wasturned to right. with resultant asymmetric filling of pharynx. Bolus is passing through left piriformrecess, leaving right side unfilled (arrow). B, Lateral projection after patient swallowedbarium, showing a diverticulum (arrow). C, Lateral projection made Slightly later,showing only filling of upper esophagus.

Fig. 1 5- 1 5 A, Ordinary dark shoelace has been tied snugly around patient's neck abovethe Adam 's apple. B, Exposure was made at peak of superior and anterior movement oflarynx during swallowing. At this moment the pharynx is completely filled with barium,which is the ideal instant for making x-ray exposure. C, Double-exposure photograph emphasizingmovement of Adam's apple during swallowing. Note extent of anterior and superiorexcursion (arrows).
