Objective: The aim of this study is to compare the postoperative outcome between endoscopic and conventional septoplasty patients. Patients and Methods: This study was carried out on one hundred patients, fifty three males and forty seven females suffering from chronic nasal obstruction due to deviated nasal septum. The patients were selected from the E.N.T. Out-Patient Clinics of Al-Azhar University Hospital (Assiut) in the period from March 2016 to January 2019.The age of the patients ranged from sixteen years to forty three years. Half of the patients underwent endoscopic septoplasty group (A), while other fifty patients underwent conventional septoplasty group (B). Pre and postoperative evaluations were done in the form of history taking, clinical examination CT scan and nasal endoscopy. Endoscopic septoplasty was done for various types of septal deviations to show the technique and to compare efficacy with conventional septoplasty. Results: It was found that endoscopic septoplasty is more effective than conventional septoplasty in treating nasal obstruction, correction of posterior deviations and septal spurs. Conclusion: We conclude from this study that complaining deviated nasal septum can be treated by various techniques. Endoscopic septoplasty gives an excellent alternative to conventional head light one with many advantages as easy, safe, rapid, limited dissection of the flaps, good access to posterior and high deviations, good illumination and visualization less complications(odema, tear, perforation, hematoma crustation).
