[An association between adenoid hypertrophy and exstra-gastroesophageal reflux disease].

Adenoid hypertrophy is a disease that mostly occurs among children of 3-5 years old. It is caused by repeated inflammation and infection of nasopharynx and its adjoin parts, or the adenoid itself, which will finally leads to pathological hyperplasia of adenoid. With so much information we have acquired about this disease, its specific mechanism remains unknown. In recent years, some researches have indicated that adenoid hypertrophy may have something to do with extra-gastroesophageal reflux, in which pepsin plays a very important role, and pepsin will do a series of pathological damages to the upper airway as it reaches the upper respiratory tract. Based on relative domestic and foreign literature, this paper attempts to make a review about the relationship between gastroesophageal reflux and adenoid hypertrophy.
