Tóm tắt	The MRC Dyspnoea Scale is a simple 5-grade ordinal classification of dyspnea severity based on the exertional threshold at which breathlessness limits activity. Developed by the UK Medical Research Council (MRC) in 1959, it remains one of the most widely used dyspnea assessments globally due to its brevity, ease of administration, and strong prognostic correlation in chronic obstructive pulmonary disease and other chronic respiratory diseases. The scale is used in clinical practice, epidemiological surveys, and longitudinal disease monitoring to grade symptom severity and guide treatment intensity.	The SNOT-22 is a 22-item disease-specific quality-of-life questionnaire designed to assess sino-nasal symptoms and their functional impact on patients with chronic rhinosinusitis, nasal polyposis, and allied conditions. Developed by Hopkins and colleagues at King's College London in 2009, it has become the most widely used instrument for measuring sino-nasal disease burden in clinical trials and rhinological practice. The SNOT-22 provides rapid, patient-centered assessment of both nasal-specific symptoms (congestion, drainage, sneezing) and general health impacts (sleep, headache, concentration).
