Severity and radiological score in nasal polyposis associated with asthma : comparison between asthmatic and non-asthmatic patients

Introduction : Chronic rhinosinusitis with nasal polyps (CRSwNP) is frequently associated with asthma. The computed tomography of paranasal sinuses is performed for the majority of patients who are going to be operated. Objective : This work aims to provide an overview of chronic CRSwNP focusing on its asthma-related radilogical presentations. Materiels and methods : This is a retrospective study about 150 patients operated for CRSwNP during a 9-year period between November 2011 and December 2020. Results : Our series included 70 men (46.7%) and 80 women (53.3%) with a sex ratio of 0.87. Asthma was noted in 62 patients (41.3%). There was no statistically significant correlation between asthma and the clinical stage of nasal polyposis (p>0.05). The mean Lund Mackay score was 21.01 in non-asthmatics and 21.94 in asthmatics. It appears that asthma was not objectively correlated with a higher Lund Mackay radiologic score (p=0.14). There is a more pronounced involvement of the sphenoidal sinuses in asthmatic patients. The involvement of the other sinuses and the ostio meatal complex was almost the same in patients with and without asthma. Conclusion : Asthma-associated CRSwNP is recognized as a more aggressive subtype of CRSwNP. In our population of patients, Asthma is an additional symptom and the radiologic presentation was not a therapeutic indicator for asthmatic patients.
