Gastroesophageal reflux and ENT disorders in childhood

Among controversies in pediatric otorhinolaryngology, the role of gastroesophageal reflux (GER) in inflammatory disorders of the upper airway remains of major concern. A laryngeal involvement by GER was demonstrated in adults and a correlation with GER has been found in pediatric populations with recurrent croup. However, although considered statistically significant, these results concern a few patients only and are inconclusive for a causal relationship. In addition, pH monitoring, often considered as the gold standard for the diagnosis of GER disease, has failed in giving normal values in ENT disorders. Eventually, upper pharyngeal and nasal involvements by GER and GER-related otitis media or otalgia have been suggested by some authors. In the 6th International Congress on Pediatric Otolaryngology, the Symposium on GER was designed to help physicians in improving their knowledge of the data from the literature and their understanding of the involved mechanisms. Bearing in mind the potential severity of GER disease, the audience also heard and debated the most up-to-date methods of assessing GER and treating it in patients with possibly related otorhinolaryngological symptoms. Here is the summary of this symposium.
