Sino-Nasal Outcome Test-22 (SNOT-22)
Sino-Nasal Outcome Test-22 (SNOT-22)
- is a validated, 22-item patient-reported questionnaire used to measure the severity of symptoms and health-related quality of life (HRQoL) in patients with chronic rhinosinusitis (CRS) (1,2)
- assesses nasal symptoms (e.g., congestion, smell loss), sleep, and emotional issues, with higher scores (0–110) indicating greater disease burden
The survey covers a range of symptoms, including:
- nasal blockage/congestion
- sneezing
- runny nose (rhinorrhea)
- thick nasal discharge
- loss of smell or taste
- cough
- ear fullness/pain
- facial pain/pressure
- difficulty sleeping/fatigue
Study evidence found the SNOT-22 to be valid and easy to use (1):
- can be used to facilitate routine clinical practice to highlight the impact of chronic rhinosinusitis on the patient's quality of life, and may also be used to measure the outcome of surgical intervention
