title: Frequency of pharyngeal reflux in children with adenoid hyperplasia.
abstract: OBJECTIVE
  The purpose of the study is to investigate whether there is any association between pharyngeal reflux and adenoid hyperplasia by using 24-h esophageal pH monitoring with a dual probe in children.
  
  
  METHODS
  The study group consisted of 30 children with adenoid hyperplasia, and the control group consisted of 12 healthy children, studied prospectively. All children underwent 24-h esophageal pH monitoring with a dual probe (distal and proximal esophageal pH monitoring). The results were evaluated by the Measurement and Analysis Software of Medical Measurement System program (Version: 7.2a).
  
  
  RESULTS
  In the study group, the frequency of pharyngeal reflux was 46.7% and the gastroesophageal reflux (GER) was 64.5%, while, in the control group, they were 8.3% and 25%, respectively. There was a significant difference between study and control groups for frequencies of pharyngeal reflux and GER. Mean adenoid nasopharyngeal ratio (ANR) was 0.78+/-0.11 in children with adenoid hyperplasia. There was not a significant difference between positive pharyngeal reflux, positive GER and mean ANR (p>0.05).
  
  
  CONCLUSIONS
  Children with adenoid hyperplasia had higher frequency of pharyngeal reflux than children at the same age healthy group. These results supported that pharyngeal reflux may play an important role in the etiology of adenoid hyperplasia.
