Video 4 - Aspiration before the swallow.

a: The first clip shows a patient as had his epiglottis resected. He is taking his first liquid bolus after surgery. The initiation of the swallow appears delayed. Because the vallecular pocket has been eliminated by removal of the epiglottis, the small amount of liquid given to him spills directly into the laryngeal vestibule before the swallow is triggered. b: The second clip shows a patient after a stroke who is not timing the onset of the swallow the bolus flow. He directs the bolus into his pharynx a few seconds before initiating the swallow and the bolus falls directly into the laryngeal vestibule.
