Decoding Pediatric Laryngopharyngeal Reflux: Unraveling Symptoms Through Multichannel Intraluminal Impedance and pH Insights.

The relationship between symptoms of laryngopharyngeal reflux (LPR) and objective reflux measurements obtained through multichannel intraluminal impedance-pH (MII-pH) monitoring remains unclear. The aim of this study was to investigate the relationship between LPR symptoms and objective reflux episodes and possible associations between fibreoptic ENT findings, eosinophil counts, and serum IgE levels with reflux episodes detected by MII-pH. In this prospective study, MII-pH monitoring, fiberoptic laryngoscopy, nasal swabs for eosinophils, total serum IgE levels, and symptom assessment (Reflux Symptom Index, RSI) were performed in all children with suspected LPR.
