Background: Adenoidectomy by conventional method is an old procedure. Several new techniques discovered in this field as an electronic molecular resonance, suction diathermy, microdebrider, endoscopy, and laser.
Objectives: to assess advantages of endoscopic assessed microdebrider adenoidectomy over the conventional method intra and post operative.
Patients and methods: 218 patients were scheduled for adenoidectomy were divided into two groups) underwent conventional curettage, group B (106 patients) underwent endoscopic assessed microdebrider. Follow up for 2 weeks ended by endoscopic evaluation.
Results: This study included 218 patients (110 males and 108 females)  aged 2 years till 14 years, divided randomly into two groups group A 112 patients group B 106 patients. This study reported statistically longer time of operation in group B than group A (13.7 for group B ± 3.5 versus 3.5 ± 1.3). Blood loss was statistically more in group A ((26.7 ± 7.5 for group A versus 17. 9 ± 5.2). Adenoid tissues remnants in group A were statistically higher than group B (27.4 % ± 11.6 for group A versus 1.7% ± .86). Regarding pain it was significantly lower in group B in the six day (4.2 ± 1.2 for group A versus 2.3 ± .5).
Conclusion: endoscopic assessed adenoidectomy is significantly better than conventional adenoidectomy regarding blood loss, post operative remnants and post operative pain.
