Diagnosis of lateral hypopharyngeal pouches: a comparative study of videofluorography and pseudovalsalva maneuver in double contrast pharyngography

Abstract

Double-contrast pharyngography using the pseudovalsalva maneuver is not a reliable method for the diagnosis of lateral hypopharyngeal pouches.

Videofluoroscopic assessment of pharyngeal stage delay reflects pathophysiology after brain infarction

“…All subjects swallowed 10 mL of a thin liquid (iohexol: nonionic water‐soluble iodine‐containing contrast medium) twice and were viewed radiographically in the lateral plane by four to five reviewers. This thin liquid was chosen because its tissue invasion is considerably less than that of barium, and it is less likely to cause pneumonia10 and acute inflammation of the bronchial wall 11, 12…”

Bilateral hypopharyngeal diverticulum

“…Lateral pharyngeal pouches are more common in older people, unlike our report, and are usually unilateral, with small dimensions but no sex, volume, or side preference. These pouches can be asymptomatic when small, but usually can cause subjective complaints such as foreign body sensation, hoarseness, globus hystericus, dysphagia, the urge to swallow again, regurgitation of undigested food, worsening in pulmonary symptoms, cervical ache, odynophagia, and suffocation 1 - 4 …”

[1][2][3][4] This entity should be diagnosed with the use of a physiological examination technique such as the video fluorographic swallowing examination, 4 in which the diverticulum can be visualized in frontal radiological images as ears with an isthmus projected at the vallecula level. 1,3 Surgery is the treatment of choice only in symptomatic patients and can be performed by either an external or endoscopic approach with or without the use of staplers.…”
