Manometry of the pharynx and the upper esophageal sphincter (UES) provides important information on the swallowing mechanism, especially about details on the pharyngeal contraction and relaxation of the UES. However, UES manometry is challenging because of the radial asymmetry of the sphincter, and upward movement of the UES during swallowing. In addition, the rapidity of contraction of the pharyngoesophageal segment requires high frequency recording for capturing these changes in pressure; this is best done with the use of solid state transducers and high-resolution manometry. UES manometry is not required for routine patient care, when esophageal manometry is being performed. The major usefulness of UES manometry in clinical practice is in the evaluation of patients with oropharyngeal dysphagia.
咽部和上食管括约肌（UES）测压提供了有关吞咽机制的重要信息，特别是有关UES 咽部收缩和松弛的详细信息。然而，UES 测压具有挑战性，因为括约肌的径向不对称以及吞咽时 UES 的向上运动。此外，食管下括约肌段的收缩速度很快，需要高频记录来捕捉这些压力变化；这最好使用固态换能器和高分辨率测压法来完成。当进行食管测压时，UES 测压不需要常规用于患者护理。UES 测压在临床实践中的主要用途是评估口咽吞咽困难的患者。
