Transoral Adenoidectomy with the Microdebrider under Transnasal Endoscopy

BACKGROUND AND OBJECTIVES: Although there have been various methods to remove adenoid, it is still difficult to achieve complete adenoidectomy due to its unfavorable anatomic structure. The aim of this study was to introduce transoral adenoidectomy using a microdebrider under transnasal endoscopy and to evaluate its efficacy. MATERIALS AND METHOD: The subjects consisted of 80 patients with adenoid vegetation. Among them, 40 patients underwent adenoidectomy using the microdebrider and other 40 cases were performed using the adenoid curette via transoral approach. Preoperative and postoperative lateral skull radiographs were obtained and compared. Also, the amount of intraoperative bleeding, complications, postoperative symptom score, and the duration of operation were compared. RESULTS: There were no statistical differences in the intraoperative bleeding, subjective symptoms after surgery and postoperative complications. But, patients, who had been performed adenoidectomy using the transoral debrider under transnasal endoscopy, had better outcomes in the nasopharyngeal ratio and the shortest nasopharyngeal diameter in lateral skull radiographs. CONCLUSION: Transoral adenoidectomy using the microdebrider under transnasal endoscopy is an effective method for more complete adenoidectomy
