 Inflammation of the nasal and bronchial mucosa characterizing rhinitis and asthma are probably manifestations of the same disease. Multiple functional observations, pathogenic and clinical support that assertion. It is noteworthy that most asthma patients, who underwent a nasal endoscopic polypectomy, improve your asthma after surgery. This improvement would be related to the administration of oral steroids that these patients usually receive after surgery, or the disappearance of nasal discomfort caused by nasal polyps to improve ventilation. But this does not explain why this improvement, in some cases lasting for months after the operation, and without receiving oral steroids. It is speculated that severe nasal inflammation due to nasal polyps stimulate the bone marrow to produce more eosinophils, an increased supply of blood eosinophils, and consequently, a major bronchial eosinophilic inflammation, aggravating asthma. However, it is noteworthy that studies have evaluated the clinical impact in asthma after endoscopic nasal polypectomy, are scarce or performed on a small number of cases, the results are inconsistent and do not allow categorically whether or not such positive association. And more importantly, none of them included measurements of airway inflammation and hypothesized relationship between bronchial eosinophilic inflammation and nasal polyposis, aclarar.La remains finding that provides nasal endoscopic polypectomy objective improvement of severe asthma it could be a future therapeutic option to consider in patients with asthma and rhinosinusal polyposis.
