[Measurement of pH of the rhinopharynx in children with gastroesophageal reflux].
The relationship between gastro-oesophageal reflux and inflammatory airway pathology is well known as regards the trachea and bronchi. It is disputed by some authors but clearly established by others as regards the pharynx and larynx (recurrent laryngitis, subglottic stenosis, laryngospasm). A number of authors have empirically observed that gastro-oesophageal reflux is associated in some cases with chronic inflammation of the rhinopharynx and middle ear. We studied the 24-hour pH of the rhinopharyngeal mucosa in 3 groups of children: 3 healthy children acting as controls, 1 child with known gastro-oesophageal reflux but without rhinopharyngeal pathology, and 2 children with both gastro-oesophageal reflux and mucosal obstruction of the nose and pharynx unascribable to the usual causes. Minimal to considerable variations of rhinopharyngeal pH were observed in children of the third group, while controls had a remarkably stable 24-hour pH (6.7 to 7.4 depending on the subject). Owing to the small number of cases studied, these results should be regarded as preliminary and devoid of significant value concerning the real impact of the acid reflux on rhinopharyngeal pathology.
