Effect of endoscopic sinus surgery on asthmatic patients with chronic rhinosinusitis

There have been several reports on the effectiveness of endoscopic sinus surgery (ESS) in asthmatic patients with chronic rhinosinusitis. Whether ESS has a positive effect on the clinical course of asthma still remains controversial. There have been several subjective evaluations but few objective results. We performed a study to evaluate the effectiveness of ESS in 19 patients with asthma who underwent ESS for rhinosinusitis. The use of antiasthma medication and postoperative asthma symptoms was analyzed. Objective changes of pulmonary function tests were evaluated. There was a significant improvement in diurnal and nocturnal asthma symptoms. Improvements in asthma medication scores were also confirmed, and individual asthma symptoms (dyspnea, cough, wheezing, and sputum production) improved significantly. Despite a reduction in use of antiasthma medication after ESS, the parameters of the pulmonary function tests did not change. Both subjectively and objectively, it seems that ESS, when used to treat asthmatic patients with chronic rhinosinusitis, can play a significant role in the clinical improvement of asthma.
