Impact of FESS on the Pulmonary Function of Patients with Chronic Rhinosinusitis

Abstract

Background and Aims There is interdependence between the upper and lower airway has led to the concept of a unified airway. Here we aim to study the impact of functional endoscopic sinus surgery (FESS) on the pulmonary function (PFT) of patients with chronic rhinosinusitis (CRS). Methods The proposed study is undertaken in the department of ENT, PGIMER & Dr. RML Hospital, New Delhi. It is a prospective study of 34 patients fulfilling the clinical criteria for (CRS) from the study period of Oct 2015 to Dec 2017 not responding to medical management and taken up for fess and follow up done with (PFT). ResultsThe maximum incidence of cases was seen in the age group [ 40 years. Chronic rhinosinusitis predominantly affected the male population. Nasal discharge was the commonest presenting complaint. A marked reduction is seen in the frequency of symptoms post-surgery. Conclusion CRS affected persons of adult age with maximum number in the age group of [ 40 years, with a male:female ratio of approximately 2:1. Percentage improvement in FEV1 and FVC is more in age group [ 40 years while percentage improvement in FEV1/FVC ratio is more in age group 31-40 years. Percentage increase in FEV1 and FVC is more in males while percentage increase in FEV1/FVC is more in females. Percentage increase in FEV1 and FVC is more in males and FEV1/ FVC is more in females. Percentage increase in FEV1, FVC and FEV1/FVC ratio is more in cases of bilateral diseases then those with unilateral disease.
