Background: Sinonasal illness frequently results in a significant reduction in quality of life, more so in chronic situations. The most frequent issue is a deviated nasal septum (DNS). This study compared the postoperative results for patients who underwent traditional septoplasty and endoscopic septoplasty. Methods: A prospective study conducted on patients, attending the Department of ENT on an in-patient basis who are diagnosed to have DNS, and other associated pathologies like chronic rhinosinusitis, polyps, and nasal cavity mass were selected on a simple random basis for this study from March 2020 to August 2021. The patients were subjected for either conventional/endoscopic septoplasty, postoperatively patients followed up, and assessed for symptom relief [Nasal Obstruction Symptom Evaluation (NOSE) score] and other complications. Results: One of the most common causes of nasal obstruction is a DNS. In our study, second-decade age was more commonly affected, men are more common (60%). Type III and type V are the most common endoscopic type of septal deviations according to the Jain Bhalerao (JB) endoscopic classification. The NOSE questionnaire was given to all patients preoperatively and postoperatively at 1 and 3 months to both the study group, and p-value was calculated, which was <0.001 when compared between conventional septoplasty and endoscopic septoplasty, which indicates it as highly significant. Conclusion: Endoscopic septoplasty is better than conventional septoplasty with regards to better visualization, good access to the posterior part of the septum, better illumination, limited resection and postoperative improvement, and complications are less in comparison with conventional septoplasty.
