Impact of Functional Endoscopic Sinus Surgery on the Pulmonary Function of Patients with Chronic Rhinosinusitis: A Prospective Study.

The study was conducted between September 2007 and March 2009 at Maulana Azad Medical College to compare the pulmonary function of patients with chronic rhinosinusitis presurgically and postsurgically. Thirty patients between 18 and 55 years of age with no prior history of respiratory illness were selected and pulmonary function test was conducted pre and post surgically. There was a significant difference between the pre and postoperative FEV1 and FEV1/FVC with the reading taken at 1 and 3 months post-surgically. The improvement in the PFT values signifies a decrease in the bronchial hyperresponsiveness as compared to the pre-operative condition.
