title: The role of 24 h pH-recording in pediatric otolaryngologic gastro-esophageal reflux disease.
abstract: The purpose of this study was to investigate the role of 24 h pH monitoring for the diagnosis of otolaryngologic including rhinologic manifestations of gastro-esophageal reflux (GER) in children and if possible to correlate the results with the efficacy of medical treatment. This is a retrospective study of 72 children from January 1997 to December 1999. The children were separated into three groups according to the main symptoms (although association of symptoms was frequent): rhinologic (n=28), laryngotracheal (n=28) and pharyngeal-otologic (n=16). With the classical gastroenterologic criterion (> or =4.2% of total time at pH < 4), the pH monitoring was positive in 56% of the patients. However, this criterion does not seem to be sensitive for otolaryngologic gastro-esophageal reflux disease (GERD) because multiple daytime short reflux episodes are often involved. Indeed, the pH monitoring was positive in 75% of the patients (82% in the rhinologic group) when a number of 40 episodes in 24h was also taken into account. The success rate of medical treatment was about 80% in case of positive pH recording. This study underlines that GER is an important factor in pediatric otolaryngologic diseases.
