Double probe pH-monitoring findings in patients with benign lesions of the true vocal folds: comparison with typical GERD and the effect of smoking

We conducted a pH-monitoring study to determine the prevalence of pathologic gastroesophageal reflux (GER+) and laryngopharyngeal reflux (LPR+) in patients with resected benign true vocal fold lesions (TVFLs) and positive reflux finding score (RFS). We compared our findings with those of patients with typical GER disease (GERD) symptoms and normal laryngoscopy. In the group of patients with TVFLs, we compared the pH-monitoring findings of smokers with those of non-smokers. Seventy-two [females 32, mean (SD) age 49.3 (13.1) years] patients with resected TVFLs (polyps: 32, nodules: 20, Reinke’s edema: 12, granulomas: 4, leukoplakia: 4) and 24 [females 14, mean (SD) age 42.2 (13.4) years] patients with typical GERD symptoms, who served as controls for the hypopharyngeal measurements, underwent 24-h double probe, hypopharyngeal and distal esophageal, ambulatory pH monitoring. Thirty-eight (52.8%) patients with TVFLs had GER+ and 52 (72.2%) had LPR+. More laryngopharyngeal reflux episodes (LPREs) were detected in patients with TVFLs compared to those with GERD ( P
