Background Chronic rhinosinusitis represents an important health care problem in the world. Deviated nasal septum leads to increased chance of impaired mucociliary clearance, osteomeatal complex obstruction, and development of rhinosinusitis. Studies have revealed the role of septoplasty in curing chronic rhinosinusitis in patients with significant septal deviation. The purpose of this study is to reveal the role of septoplasty alone or combined with functional endoscopic sinus surgery in

... ing the outcome of chronic rhinosinusitis in patients with significant septal deviation. Results Postoperative computed tomography findings in group A (underwent septoplasty only) were mild opacity of ethmoid (25%), sinus mucosal thickening (15%), and occluded osteomeatal complex with discharge (25%). Postoperative computed tomography findings in group B mild opacity of ethmoid (30%), sinus mucosal thickening (20%), and occluded osteomeatal complex with discharge (30%). The Sino-Nasal Outcome Test score in group A decreased significantly from 85.75 to 28.85 (P < 0.05). In group B (underwent combination of septoplasty and functional endoscopic sinus surgery), the Sino-Nasal Outcome Test score also decreased significantly from 87.75 to 32.55 (P < 0.05). The improvement was 85% in group A and 80% in group B. Conclusion The post-operative improvement has no significant difference between the two groups. Hence, we suggest that septoplasty alone can be adequate for the treatment of chronic rhinosinusitis with septal deviation.
