Evaluation of endoscopic sinus surgery by Glasgow benefit inventory

Introduction: Functional endoscopic sinus surgery is a common adjunct to medical therapy in cases of chronic rhinosinusitis and nasal polyposis. Aim: The objective of this study was to assess patients' quality of life up to two years after endoscopic sinus surgery. Method: Fifty consecutive patients attending a rhinology clinic filled in the Glasgow benefit inventory. The patients were divided into three groups according to the time period elapsed since surgery (i.e. six months, 12 months or up to two years). Results: The results showed that, generally, the Glasgow benefit inventory scores indicated a benefit from the procedure. Overall, surgery led to statistically significant improvements in both total and general scores (p < 0.05). Comparison of endoscopic sinus surgery with nasal polypectomy (plus endoscopic sinus surgery) indicated a greater benefit for polyp disease. No statistical difference was observed between the scores for females vs males or for various post-operative follow-up periods.
