Diagnosis and clinical presentation of pediatric laryngopharyngeal reflux (LPR) is still controversial. The aims of this work were to study the possibility of performing 24-hour oropharyngeal pH monitoring for children in the outpatient clinic setup and to explore the results of this test in correlation to airway-related problems.
In this descriptive qualitative study, 26 children suffering from airway-related problems were included. Oropharyngeal 24-hour pH monitoring was performed for all subjects in the outpatient clinic setting. The distribution of airway diagnoses among the study group was studied versus the results of the pH monitoring.
There were 16 males and 10 females participated in the study with a mean age of 6.88 (SD, ±5.77) years. Thirty-five percent of the patients were under the age of 3 years (range, 11 months to 3 years). Eight-five percent of the patients tolerated the pH probe insertion and completed 24-hour of pH recording. Laryngomalacia and subglottic stenosis (SGS) were more frequently reported in the positive LPR patients (77%).
Oropharyngeal 24-hour pH monitoring can be conducted for children in the outpatient setup even in young age children below 3 years old. Among the positive LPR group, SGS and laryngomalacia were the most commonly reported airway findings.
小儿喉咽反流（LPR）的诊断和临床表现仍存在争议。本研究的目的是探讨在门诊环境下对儿童进行24小时口咽pH监测的可能性，并探讨该测试结果与气道相关问题的相关性。
在这项描述性定性研究中，纳入了26名患有气道相关问题的儿童。在门诊环境中对所有受试者进行口咽24小时pH监测。研究了研究组中气道诊断的分布情况与pH监测结果的关系。
共有16名男性和10名女性参与研究，平均年龄为6.88（标准差，±5.77）岁。35%的患者年龄在3岁以下（范围为11个月至3岁）。85%的患者耐受pH探头插入并完成了24小时的pH记录。在LPR阳性患者中，喉软化和声门下狭窄（SGS）的报告更为频繁（77%）。
即使是3岁以下的幼儿，也可以在门诊环境中对儿童进行口咽24小时pH监测。在LPR阳性组中，SGS和喉软化是最常报告的气道发现。
