Treatment Outcome Post Endoscopic Sinus Surgery(ESS) in Patients with Chronic Rhinosinusitis (CRS).

Chronic rhinosinusitis (CRS) is one of the most prevalent conditions in medicine causing a considerable amount of healthcare expenditure. This study was performed to clinically diagnose chronic rhinosinusitis with or without polyps and to measure the intensity of patients' symptoms and treatment outcomes. This was a prospective cohort study, which included 70 patients diagnosed with CRS according to the EPOS-2012 and were given SNOT-22 questionnaire preoperatively, which was repeated on 1st, 4^th, and 12th weeks post-op to determine the treatment outcome. Patients were divided into three groups according to their predominant histopathological features and the treatment outcomes were assessed based on SNOT-22 scoring system. According to our study, ESS effectively raised the quality of life for CRS patients, and one week after surgery, there was a significant improvement in total symptoms (from 49.01 ± 14.83 to 21.91 ± 8.88). it was noted that there was a decrease in SNOT-22 scores at various intervals from baseline to week 12. The four subscales of the SNOT-22 test (rhinological symptoms, ear and facial symptoms, sleep function, and psychological difficulties) showed significant improvements in quality of life across all groups, and this relationship extended beyond the relationship with rhinological symptoms. These improvements were statistically significant after three months of post operative medical therapy. SNOT-22 is determined to be reliable and convenient to use. After ESS, all of the symptoms in our study showed a drop in SNOT-22 scores from week 1 to week 12, indicating an improvement in overall symptoms. Therefore, it can be used to monitor the success of surgical intervention in addition to medicinal therapy.
