Background: Deviated nasal septum (DNS) is a quite common problem in all age groups Although DNS is an idiopathic problem but encountered by otolaryngologists A variety of surgical procedures or approaches are being practiced by ENT surgeons that are cost-effective on the other hand safer post-surgically. Materials and methods: Sixty patients aged between 18 and 50 years having DNS, nasal obstruction chronic rhinosinusitis, epistaxis, and headache were studied, 30 patients were operated on by conventional septoplasty, 30 patients by endoscopic septoplasty and post-surgical complications were studied. Results: A total of 14 (23.3%) had right DNS among them eight had undergone conventional and six for endoscopic septoplasty. A total of 12 (20%) had left DNS out of them seven underwent conventional five for endoscopic septoplasty. A total of 10 (16.6%) had spur among them six had undergone conventional four for endoscopic septoplasty, 18 (30%) had hypertrophied IT, eight underwent conventional 10 patients underwent endoscopic septoplasty 2 (3.33%) had polypoid MT undergone endoscopic septoplasty 1 (1.6%) had concha bullosa undergone endoscopic septoplasty, 3 (5%) had nasal discharge two underwent conventional and one for endoscopic septoplasty. The operative complication was 1 (3.3%) bleeding observed in conventional septoplasty 2 (6.6%) synechiae observed in conventional 1 (3.3%) in endoscopic septoplasty 5 (16.6%) DNS recurrence was observed in conventional 2 (6.6%) in endoscopic, 2 (6.6%) Epistaxis in conventional 1 (3.33%) in Endoscopic septoplasty crusting was observed only in conventional septoplasty. Conclusion: The majority of postoperative complications were observed only in conventional septoplasty. As endoscopic septoplasty was more illuminative least incision, precise cutting is an ideal technique for nasal diseases.
