The subject is the same as in Video 1. A marker disk is present anteriorly. During the swallow there is poor opening of the UES and substantial retention of bolus within the hypopharynx. During a subsequent dry swallow, some of this material is seen to enter the airway (dark arrowheads). The speed of the videoclip has been reduced slightly from real time to aid comprehension.
