Abstract Objective We aimed to elucidate the dynamics of deglutition during head rotation by acquiring 320‐row area detector computed tomography (320‐ADCT) images and analyzing deglutition during head rotation. Methods This study included 11 patients experiencing globus pharyngeus. A 320‐ADCT was used to acquire images in two types of viscosity (thin and thick), with the head rotated to the left. We measured the movement time of deglutition‐related organs (soft palate, epiglottis, upper esophageal sphincter [UES], and true vocal cords) and pharyngeal volume (bolus ratio at the start of UES opening [Bolus ratio], pharyngeal volume contraction ratio [PVCR], and pharyngeal volume before swallowing [PVBS]). A two‐way analysis of variance was performed for statistical analysis, and all items were compared for significant differences in terms of head rotation and viscosity. EZR was used for all statistical analyses (p‐value
