This study will validate translated versions of the same set of questionnaires simultaneously in the centers involved after recruiting a total of 1000 patients, while data collection, statistical analysis, and creation of the study report will be carried out by the statistical department of the University of Leuven.
Patients will be recruited from the regular ENT practice of their hospital to minimize the complexity of the study.
