목적: Septoplasty is well-described surgical technique for management of nasal airway obstruction (NAO) and improve access for endoscopic sinus surgery (ESS). The advances in endoscopic techniques have facilitated endoscopic septoplasty (ES). A study was carried out to compare the pre and postoperative symptoms, objective results among patients of ES and CS. 방법:Thirty patients symptomatic deviated nasal septum (DNS) were randomly divided into two groups of 15 patients each. Demographic data, operative indications, adjunctive procedures, pre and postoperative subjective, objective results were recorded by questionnaire, visual analogue scale (VAS), Glatzel mirror (GM) and peak nasal inspiratory flow (PNIF) measurements,respectively. 결과:Indications for all septoplasy included NAO (76.7%), facial pain (13.3%) and ESS access (10%). The most common concomitant diagnoses included turbinate hypertrophy (43.3%), chronic rhinosinusitis (16.7%), allergic rhinitis (13.3%) and sinonasal polyposis (6.7%). Concomitant procedures performed included turbinate reduction (43.3%) and ESS (16.7%). In the postoperative facial swelling, pain and NAO, ES group was significantly better than CS group. (p<0.05) In both groups, preoperative narrowed side were fixed postoperatively, which was confirmed (p<0.01) by using GM after 2 months. And preoperative PNIF volume were also significantly increased (p<0.01) after 2 months by PNIF measuring device confirmation, respectively. 결론:In this study, there is no difference in objective postoperative nasal findings between two groups. And ES has more limitation on subperichondrial and subperiosteal plane dissection in deviated nasal septum. But improvement of postoperative symptoms is significantly faster in ES group than CS group. And ES has another several advantages than CS as like the enhanced visualization of septal deviation on operation field and facilitating of teaching endeavors through video monitors.
