Abstract

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.
