- The hypopharynx and
cervical esophagus are to be included in the esophageal study if disease is
suspected in this region or if the patient refers symptoms to the throat or neck.
- Perform the study
with the patient upright (or as nearly upright as possible).
- Use "thick barium"
(high-density, high-viscosity).
- Record swallowing
dynamics in both lateral and AP projections with a digital or photospot
camera set at 4 frames per second and 90 kVp.
- Record anatomy of
hypopharynx in AP and lateral projections while patient is phonating.
- Explain the procedure
to patient. You will count "one, two, three" out loud. For each swallow, you
will have the patient swallow barium on the count of "three", but you will
begin rapid sequence (4/sec) filming with the camera on the count of "two".
