| Abstract: | To investigate the mechanism whereby adenoidectomy influences the subsequent course of patients with chronic otitis media with effusion, we analyzed, on the basis of adenoid size, the outcomes of 476 children randomly assigned to receive, after paracentesis and aspiration of the middle ear, either no treatment, tympanostomy tubes, adenoidectomy, or both. The two groups receiving adenoidectomy did significantly better than those who did not, and the effect was independent of adenoid size. This suggests that reduction of the adenoidal bacterial reservoir may be the mechanism whereby adenoidectomy is effective. |
