Figure 1
Figure 1 Videofluoromanometry study. A: Aspiration after swallowing (black arrow) with stagnation in the glossoepiglottic valleys and piriform sinuses (white arrows). Incomplete upper esophageal sphincter (UES) release (arrow); B: The same occurred with the head-rotated posture; stasis persisted at the pharyngoesophageal junction (white arrow), but there was no aspiration of the contrast medium. The UES was fully open (dashed box).

Figure 2 Videofluoromanometry study. A: Aspiration during swallowing (arrow) for the reduced laryngeal closure with an incomplete upper esophageal sphincter (UES) release; B: The same occurred in the course of the chin-down posture; this posture resolved the aspiration because it placed the epiglottis in a more protective position of the airways and restricted the airway entrance.
