Evidence for adenoidectomy in children with glue ear very uncertain

Adenoidectomy may have a small beneficial effect on the resolution of OME – fewer children who received adenoidectomy had persistent effusion at up to 3 months (low-certainty evidence) and up to 12 months (very-low-certainty evidence) of follow-up. For those who received adenoidectomy and ventilation tubes versus no treatment, there was an improvement in mean hearing threshold, but the evidence was very uncertain. This effect was much smaller after 1 and 2 years of follow-up, but it should be noted that many children in the control group had also received surgery by this time.
