The ideal adenoidectomy procedure would make it easier for the surgeon to see the adenoid pad and allow for efficient tissue removal with minimal blood loss. We aimed to compare and evaluate endoscopic-assisted adenoidectomy either by microdebrider or coblation in terms of blood loss, pain, intraoperative time and short-term complications

Methods: This randomized prospective clinical trial included 54 patients with hypertrophied adenoiditis.Group I (27 patients): included patients underwent endoscopic-assisted adenoidectomy with microdebrider. Group II (27 patients): included patients underwent endoscopic-assisted adenoidectomy with coblation. Assessment of operation time, blood loss, pain, associated trauma, complete removal, and occurrence of bleeding (nasal/oral) was done for all patients.

Results: Operation time was significantly lower in group 1 (microdebrider) than group 2 (coblation) which was 20.19 min in average in group 1 and 34.26 min in group 2 (p <0.0001). Postoperative pain scores as assessed by VAS score showed significantly higher pain scores 1h post operative (p=0.001) and 1 day postoperative (P <0.0001) in Group 1 (microdebrider ) as compared to Group 2 (coblation). There was no statistically significant difference between both groups regarding Post-operative complications

Conclusion: Endoscopic-assisted coblation adenoidectomy is a safe and effective method achieving a complete adenoidectomy with less blood loss, as well as postoperative complications and a shorter duration of postoperative pain
