흡입식 절삭기를 이용한 비내시경하 경비강 아데노이드 절제술

Background and Objectives: The conventional adenoidectomy with adenoid currette, adenotome, and adenoid punch result in various complication such as bleeding and damage to the mucosa of posterior nasopharyngeal wall or orifice of Eustachian tube. This procedure may be left relatively much remnant adenoid tissue. The purpose of this paper is to compare conventional adenoidectomy with transnasal microdebrider-assisted adenoi- dectomy under endoscopy based on postoperative outcome and intraoperative effectiveness. Subjects and Methods: We performed a prospective study comparing sixty seven cases of conventional adenoidectomy with sixty two cases of transnasal microdebrider-assisted adenoidectomy under endoscopy. We evaluated postoperative change of symptoms, endoscopic grade, lateral skull radiographs, operation time and complication. Results: There was no statistical difference in the subjective symptoms and operation time. However, it was found that patients, who had been performed transnasal microdebrider assisted adenoidectomy under endoscopy, had better outcomes in the postoperative endoscopic grade and improvement in lateral skull radiographs. Conclusion: Compared to the conventional method, transnasal microdebrider assisted adenoidectomy under endoscopy removed adenoid tissue precisely and safety. So we suggest that this procedure is an attractive surgical method in removal of severe vegetated adenoid. (J Clinical Otolaryngol 2007;18:41–46)
