This study aims to evaluate the subjective, objective and overall quality of life improvement in CRS patients following FESS surgery. Sinonasal outcome index-22, modified Lund-Mackay score and Rhinosinusitis Disability Index were used to evaluate subjective, objective and overall quality of life in patients with CRS. The questionnaires were asked before the surgery and three months after surgery. A total of 110 patients were enrolled in the study. All three types of evaluation showed improvement following FESS surgery. FESS in CRS patients refractory to medical management caused significant improvement in symptom intensity, endoscopic score and overall quality of life.en-USSinonasal outcome index-22Modified Lund- Mackay scoreRhinosinusitis disability indexArticle
