Objectives: To analyze the area under the curve (AUC) from 24-hour pharyngeal pH probes and evaluate this parameter as a predictor of disease severity for laryngopharyngeal reflux.
Methods: Eighty patients met inclusion criteria of a completed 24-hour pharyngeal pH probe and Reflux Symptom Index (RSI) questionnaire. The AUC was calculated below a pH threshold of 5.
