Changes in the hypopharynx may suggest supraesophageal reflux disease

Supraesophageal reflux disease is difficult to diagnose because its markers are not well defined. However, debate among gastroenterologists continues about the possibility that changes in the appearance and function of the hypopharynx can be valid indicators of atypical reflux disease. Detecting these indicators presents a challenge, albeit a necessary one, if reflux disease is to be identified and treated appropriately. This paper reviews the anatomical and functional characteristics of supraesophageal reflux disease.
