Objectives:
The goal was to estimate the prevalence of laryngopharyngeal reflux (LPR) in patients with laryngeal and voice disorders.
Study Design And Setting:
This was a prospective study of 113 unselected, new patients with laryngeal and voice disorders. Patients completed an extensive medical history form including a reflux symptom profile. A comprehensive otolaryngologic examination was performed with photographic transnasal fiberoptic laryngoscopy. Patients with both symptoms and findings of LPR (78/133, 69%) underwent ambulatory 24-hour double-probe pH monitoring.
Results:
Seventy-three percent (57/78) of patients undergoing pH testing had abnormal studies. Thus 50% (57/113) of the entire the study population had pH-documented reflux. Of the diagnostic sub-groups studied, the highest incidence of reflux was found in patients with vocal cord neoplastic lesions (88%) and patients with muscle tension dysphonias (70%). LPR was infrequently found in patients with neuromuscular disorders.
Conclusion:
LPR occurs in at least 50% of all patients at our center with laryngeal and voice disorders at presentation.
