Background: To compare the effectiveness of endoscopic septoplasty and conventional septoplasty in the treatment of deviated nasal septa.Materials and methods: The research comprised 80 patients, of either gender, between the ages of 20 and 60, who had symptomatic deviated nasal septum (DNS). Patients experiencing symptoms from a deviated nasal septum do not respond to non-invasive medical therapy. This research covered five symptoms for consideration: nasal obstruction, postnasal discharge, headache, epistaxis, and hyposmia. The research excluded individuals with allergic or vasomotor rhinitis, nasal masses, nasal polyps, and revision patients. Group A consisted of 50 patients who received endoscopic septoplasty (ES), whereas Group B consisted of another 50 instances that underwent conventional septoplasty (CS) under local anaesthesia.Results:The current investigation revealed that the most common symptom before surgery was nasal blockage, affecting 91% of the participants. This was followed by headache (55%), postnasal drip (50%), hyposmia (48%), and epistaxis (31%). During the 90-day follow-up visit, residual deviation was seen in 42.5% of patients in the conventional group, compared to just 7.5% of patients in the endoscopic group (P = 0.001). In the conventional group, 15 out of 40 patients (37.5%) acquired synechiae, whereas in the endoscopic group, only 4 out of 40 patients (10%) got synechiae. The difference in the incidence of synechiae between the two groups was statistically significant (P = 0.01).Conclusion: Both conventional and endoscopic septoplasty were found to be highly effective in alleviating symptoms. However, endoscopic septoplasty demonstrated significantly superior results due to its precise identification of pathology, improved illumination, enhanced accessibility to remote areas, and magnification. ES is linked to a significant decrease in post-operative morbidity because it limits the occurrence of flap dehiscence.
