OBJECTIVES: The aim of this study was to determine the severity of extraesophageal reflux (EER) in patients with various degrees of chronic rhinosinusitis (CRS), and particularly in patients with simultaneous bronchial asthma.
RESULTS: A total of 90 patients (30 in each group) were recruited for the study. Pathological EER was significantly often present in group III when compared with group I and group II in all parameters analyzed (RYAN score, number of EER episodes, total percentage of time below pH 5.5). Furthermore, patients from group III had undergone more surgeries in the past.
CONCLUSION: Patients with CRS with nasal polyps and simultaneous bronchial asthma suffer from significant EER. Antireflux therapy can be recommended for these patients. However, the effect has to be confirmed in further studies.
