The Sino Nasal Outcome Test 22 score in persons without chronic rhinosinusitis

ObjectivesTo determine the Sinonasal Outcome Test 22 (SNOT 22) score in persons without chronic rhinosinusitis. Design and settingAs part of a trans-European study selected, respondents to a survey questionnaire were invited for a clinical visit. Subjective symptoms and rhinoscopy were used for the clinical diagnosis of chronic rhinosinusitis according to EPOS. ParticipantsA total of 366 persons participated at the clinical visit and of these 268 did not have chronic rhinosinusitis. All participants completed the SNOT 22. Main Outcome measuresThe SNOT 22. ResultsThe SNOT 22 score ranged from 0 to 67 with a mean score of 10.5 (CI: 9.1-11.9) and the median score was 7. Persons with allergic rhinitis and blue-collar workers had a significant higher score. ConclusionThe median value of 7 is taken as the normal SNOT 22 score in persons without CRS and can be used as a reference in clinical settings and research. Allergic rhinitis and occupation affect SNOT 22 in persons without CRS.
