Pharyngeal Manometry

Testing Information: Pharyngeal Manometry

What is Pharyngeal Manometry?

The Pharyngeal Manometry Test is a test done to evaluate the swallowing mechanism. Pharyngeal and upper sphincter manometry can detect failure of relaxation of the sphincter and how well the coordination is between the contraction of the pharynx and the relaxation of the upper esophageal sphincter.


Some patients may experience throat discomfort and nosebleed.

What to do the night before the procedure

Do not eat or drink anything for 6 – 8 hours prior to your test.

Preparing for the procedure

Do not smoke the day of your 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.

During the procedure

This study is done by passing small pressure transducers through the nose into the throat and upper esophagus and measuring pressures from different locations during swallowing of 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 – 60 minutes.

After the procedure

You may drive yourself home after the procedure.
