OBJECTIVE
To assess pharyngeal acid reflux (PAR) exposure with flexible laryngoscopy-guided pharyngeal pH monitoring in infants with laryngitis.
STUDY DESIGN
Tertiary care children's hospital.
SUBJECTS AND METHODS
Charts of 10 infants with laryngitis who underwent pharyngoesophageal pH monitoring were reviewed. Data included history, physical examination, and pharyngoesophageal pH monitoring findings.
RESULTS
Six infants had PAR. Two patients were on acid suppressive therapy and exhibited PAR. The number of PAR observed in six infants ranged between 1 and 81. The percent acid exposure time (AET) in the pharynx was between 0.1% and 1.2%. Esophageal acid reflux documented in nine infants ranged between 5 and 173. The percent AET in the esophagus was between 0.1% and 4.8%.
CONCLUSIONS
The majority of the studied infants with laryngitis had PAR. Not all esophageal acid reflux reached the pharynx. Pharyngeal pH monitoring provides additional information that cannot be obtained with esophageal pH monitoring in infants with laryngitis.
目的
通过柔性喉镜引导下的咽部pH监测评估喉炎患儿的咽部酸反流（PAR）情况。
研究设计
三级护理儿童医院。
研究对象与方法
回顾了10例接受咽食管pH监测的喉炎患儿的病历。数据包括病史、体格检查和咽食管pH监测结果。
结果
6例患儿存在PAR。2例接受抑酸治疗的患儿也出现了PAR。6例患儿中观察到的PAR次数在1至81次之间。咽部的酸暴露时间（AET）百分比在0.1%至1.2%之间。9例患儿记录到的食管酸反流次数在5至173次之间。食管的AET百分比在0.1%至4.8%之间。
结论
大多数研究的喉炎患儿存在PAR。并非所有食管酸反流都会到达咽部。咽部pH监测提供了在喉炎患儿中通过食管pH监测无法获得的额外信息。
