Eligible patients found to have nasal polyps will be offered the chance to participate in this study. They will undergo non-invasive pH probe monitoring for 24 hours. If extraesophageal (laryngopharyngeal) reflux is discovered, they will be provided (at no cost) proton pump inhibitor medication (PPI), prescribed in accordance with published standards in the otolaryngology literature. Their polyposis will be treated as any other patient presenting with polyposis; participation in the study will not affect the course of polyp treatment. The incidence of recurrence will be monitored and recorded over the first year after treatment.
