the effect of endoscopic sinus surgery in chronic rhinosinusitis patients with concurrent asthma

background chronic rhinosinusitis (crs) and asthma are among the most important health-related conditions with evident socio-economic effects. the relationship between asthma and crs has been considered in medical references for centuries. previous studies have shown that treatment interventions targeting disease in one part of the airway are effective for general asthma management. however, the effect of endoscopic sinus surgery (ess) in crs patients with concurrent asthma remains controversial. therefore, we aimed to assess the effects of ess on improvement of asthma in crs patients with concurrent asthma. objectives the aim of this study was to evaluate the impact of ess on asthma in crs patients. methods twenty-five crs patients with asthma who met our inclusion criteria after taking a complete history underwent physical examination and diagnostic nasal endoscopy, and the asthma control test (act) questionnaire was administered to them. six months after ess, the patients’ asthma was again assessed using the act questionnaire. results overall, the mean act score significantly increased from 12.56 at the baseline to 20.71 after a six-month follow up period (0.001). conclusions given the remarkable improvement in asthma control levels, ess can be considered a useful method for treating crs patients suffering from asthma.
