Telescopic-assisted radiofrequency adenoidectomy: a prospective randomized controlled trial.

OBJECTIVES/HYPOTHESIS: The objective was to conduct a prospective randomized controlled trial describing and investigating the efficacy and safety of transoral telescopic-assisted radiofrequency adenoidectomy in young children.

STUDY DESIGN: Prospective randomized controlled trial.

METHODS: One hundred twenty patients who were 36 months of age or less and planned to undergo adenoidectomy or adenoidectomy with insertion of tympanostomy tubes were included in the study. Children were prospectively and randomly assigned into two equal treatment groups: the telescopic-assisted adenoidectomy using radiofrequency curette and the conventional adenoid-curette adenoidectomy. The main parameters included visual analogue scale score for nasal breathing, amount of blood loss, operating time, completeness of adenoid resection, smoothness of postoperative recovery, and complications.

RESULTS: Both groups had a significant improvement in the visual analogue scale score after surgery with no evidence for a significant difference between the conventional adenoid-curette and radiofrequency groups. The amount of blood lost during radiofrequency adenoidectomy was minimal, with a mean difference of 31 mL and a median difference of 26 mL. There was a tendency for shorter operative time in the radiofrequency group, but this did not reach a statistical significance. No evidence for a significant difference was noticed in the smoothness of postoperative recovery or complication rate.

CONCLUSION: Telescopic-assisted radiofrequency-curette adenoidectomy allows removal of huge adenoids completely in a precise, easy, and cost-effective procedure, with minimal blood loss and short operating time. The use of transoral telescopes provides a clear visualization that helps complete removal of the adenoids, reduction of unnecessary trauma, and effective control of bleeding.
