Simultaneous videofluoroscopy with anatomical referents (left) and high-resolution manometry with pressure-related regions of interest (right). Velopharyngeal pressure relates to pressure generated from the soft palate and pharyngeal constriction. Hypopharyngeal pressure relates to pressure generated in between the tongue base and upper esophageal sphincter. Upper esophageal sphincter may cover up to 6 pressure sensors due to movement of pharyngeal and laryngeal structures during swallowing.
