Video 2 - Videofluoroscopic example of cricopharyngeal bar.

The videoclip is of a lateral view on videofluoroscopy in a patient with a cricopharyngeal bar, which is seen impinging on the barium column posteriorly (arrow). Note that after completion of the initial swallow there is slight retention of residue in the valleculae and piriform sinuses. This is mostly cleared on a subsequent dry swallow. The speed of the videoclip has been reduced slightly from real time to aid comprehension.
