Preliminary Exploration of Variations in Measures of Pharyngeal Area During Nonswallowing Tasks.

Purpose: Age- and disease-related changes in oropharyngeal anatomy and physiology may be identified through quantitative videofluoroscopic measures of pharyngeal area and dynamics. Pixel-based measures of nonconstricted pharyngeal area (PhAR) are typically taken during oral bolus hold tasks or on po...
