The pharyngeal manometry test evaluates your swallowing. Pharyngeal and upper sphincter manometry can detect the sphincter’s (muscle that maintains constriction of a natural body passage) failure to relax and assess the coordination between the contraction of the pharynx and the relaxation of the upper esophageal sphincter.
About the Pharyngeal Manometry Procedure
This test is done by passing small pressure transducers through the nose into the throat and upper esophagus and measuring pressures from different locations while you swallow water or different food substances, such as liquid or solid material like pudding. This is sometimes done using simultaneous X-rays. The test lasts about 45 to 60 minutes. You may drive yourself home afterwards.
Some patients may experience throat discomfort and nosebleed.
Patients should not eat or drink anything for six to eight hours prior to the test, or smoke the day of the test. Unless your doctor instructs you otherwise, do not take your medications the day of the test. If you are an asthma patient, bring your inhaler.
