The Diagnostics of Extraesophageal Reflux With the Restech System

The aim of the project is to define the frequency with which EER is present in patient with chronic rhinosinusitis (CHR). The measurement will be carried out with a 24-hour monitoring of the pH using the Restech system. This modern device is equipped with a narrow antimony probe. The sensor is able to record not only liquid but also aerosol reflux episodes. The second aim is to determine the relation among EER, CHR and asthma bronchiale. We will compare the presence of reflux in three different patient groups (1. CHR without nasal polyposis, without asthma bronchiale or ASA syndrome, 2. CHR with nasal polyposis, without asthma bronchiale or ASA syndrome, 3. CHR with nasal polyposis and asthma bronchiale and/or ASA syndrome). We expect to find a significantly more frequent presence of EER in patients with CHR and asthma bronchiale or ASA syndrome. In case our hypothesis is confirmed, it will be especially these patients(with a difficult to manage nasal polyposis) benefiting from the antireflux therapy.
