Sino-Nasal Outcome Test-22 is a questionnaire that evaluates the specific quality of life in chronic rhinosinusitis and was widely used in scientific literature. The aim of our study was to translate and culturally adapt Sino-Nasal Outcome Test-22 for the Portuguese reality and validate the version obtained for use in Portugal. ⋯ Until now, there were no validated questionnaires to evaluate quality of life in patients with chronic rhinosinusitis in Portugal. Translation and validation of Sino-Nasal Outcome Test-22 in Portugal will allow a more consistent assessment of the specific quality of life of these patients and the comparison with international data. Thus, we recommend this version for use with the Portuguese population with chronic rhinosinusitis.
