 Introduction: Based on the unified airway concept, Bronchial Asthma and Chronic Rhinosinusitis have significant effect on each other in terms of disease severity and progression.  Aim: To find clinical co-relation between the degree of severity of sinonasal symptoms of Chronic Rhinosinusitis in asthmatic patients.  Methodology: A prospective study was conducted to examine the co-relation between the sino nasal symptoms severity of CRS in asthmatic patients using SNOT-22 questionnaire. 100 patients with bronchial asthma were evaluated for the severity of the sinonasal symptoms of Chronic Rhinosinusitis. A score of more than 22 was considered to be significant.  Results: 60 patients with bronchial asthma were evaluated. SNOT-22 scoring was mild (8-20) in 9 patients, moderate (20-50) in 32 patients and severe (more than 50) in 9 patients. The mean average score was 41.4.  Conclusion: Chronic Rhinosinusitis and Asthma are in fact dependent and have disastrous effects on each other if not controlled properly. Therefore Bronchial Asthma and Chronic Rhinosinusitis must be regarded and dealt with as a unified airway disease for better disease control.
