B-SIT, Brief Smell Identification Test. RARS, recurrent acute rhinosinusitis. CRSsNP, chronic rhinosinusitis without nasal polyposis. CRSwNP, chronic rhinosinusitis with nasal polyposis. QOL, quality of life. SD, standard deviation. SNOT-22, 22-Item Sinonasal Outcome Test. RSDI, Rhinosinusitis Disability Index.
