코블레이터와 회전식 흡입기를 이용한 하비갑개 수술의 장기적 효과에 대한 비교 연구

Abstract

Background and Objectives：Various surgical methods have been tried to relieve the symptoms of nasal obstruction in patientswith inferior turbinate hypertrophy. Recently, coblators that use radiofrequency and microdebriders are increasingly usedin turbinate surgery. The aim of this study was to compare the long-term postoperative outcome between the coblator-assistedand microdebrider-assisted partial turbinoplasty. Subjects and Method：We selected 60 patients who had nasal obstruction andhypertrophied turbinate mucosa that was refractory to medical treatment. Thirty patients were treated with coblator (group 1)and 30 patients were treated with microdebrider (group 2). Postoperative changes in degree of nasal obstruction were evaluatedprospectively at 3, 6 and 12 months after the procedure. Cross-sectional area of second notch and volume of nasal cavity werecompared at 12 months after operation. Operation time, duration of crust formation, postnasal drip and postoperative bleedingwere also compared. Results：Nasal obstruction was improved significantly in both groups. However, statistical significance ofimprovement and rate of patient’s satisfaction at 12 months after surgery was higher in group 2. There were no significant differencesin the degree of postnasal drip, operation time and duration of crust formation between two groups. Conclusion：Thisstudy suggests that microdebrider-assisted partial turbinoplasty is more effective and satisfactory in long-term relief of nasalobstruction and reduction of mucosal volume in the anterior head of inferior turbinate.
