Video 1 - Videofluoroscopic example of premature spill.

The videoclip is from a patient with severe oropharyngeal dysphagia. The orientation is anterior-posterior. Before the swallow onset, retained material is seen in the valleculae and piriform sinuses (the oval density is an external marker). Before the swallow onset premature spill (white arrow) is observed on the right. The speed of the videoclip has been reduced slightly from real time to aid comprehension.
