[Pharyngeal acid load and different functional endoscopy findings]. HNO. 2019 Aug 12;: Authors: Michel F, Dannesberger R, Stroh T, Fritsche R, Ahrens P Abstract The findings of functional endoscopy (upper esophageal sphincter insufficiency, cardia insufficiency, esophagitis, gastric heterotopia, axial sliding hernia, and visible aerosols) can be traced back to pharyngeal acid exposure by oropharyngeal pH measurement. Significantly increased pharyngeal acid loads are seen in gastric heterotopy and axial sliding hernia. For all measured statistics, the pharyngeal acid load is in the pathological or even very pathological range. The value of functional endoscopy in the context of laryngopharyngeal reflux diagnosis is clearly documented. The findings "heterotopic gastric mucosa" and "axial sliding hernia" may cause marked airway symptoms and a pathogenetic relationship with otorhinolaryngologic reflux-associated symptoms must be postulated for these entities.
