Introduction: Deviated nasal septum (DNS) is a common condition, mainly causing nasal obstruction in a person. It is usually asymptomatic but may cause interference in daily life in some. Hence symptomatic DNS patients undergo septoplasty. Septoplasty is a conservative surgical procedure, correcting the deviated parts of nasal septum. Some patients have persistent symptoms even after septoplasty. NOSE (Nasal Obstruction Symptom Evaluation) scale was used as a tool to measure nasal obstruction and evaluate the outcomes of septoplasty, in DNS patients. Aim of the Study: To compare the NOSE scores before and after conducting septoplasty in DNS patients and evaluate the effectiveness of septoplasty. Material and Methods: A prospective study was conducted in a tertiary care hospital in DNS patients undergoing septoplasty. NOSE scores were obtained preoperatively and postoperatively from them and analyzed. Results: A total of 20 patients were included in the study, for a period of 2 months from January 1, 2020 to February 28, 2020. Both male and female were included in the study. The mean age of the patients was 37.2 years. The preoperative NOSE scores showed mild obstruction in 2 (10%), moderate obstruction in 11(55%) and severe obstruction in 7(35%). The postoperative NOSE scores showed persistent nasal obstruction in 1 (5%) patient. The mean and SD of preoperative NOSE score was 47.25 and 19.83 respectively. The mean and SD of postoperative NOSE score was 0.25 and 1.11 respectively (P__ampersandsignlt;0.001). The postoperative NOSE scores were less than the preoperative NOSE scores. Conclusion: Each patient showed improvement in nasal symptoms after proper treatment and septoplasty was found to be effective in 95% of the patients.
