It looks if that Cochrane review has been removed because it's been split into two separate reviews, the relevant one of which is, I think, this? www.ncbi.nlm.nih.gov/m/pubmed/26465274/
Is that right?
If so, what you're saying about "most children" getting better with time doesn't quite seem to reflect it correctly - it says just under half in the conclusion here.
It also states that there's
"moderate quality evidence that adenotonsillectomy provides benefit in terms of quality of life, symptoms and behaviour as rated by caregivers"
And....
"high quality evidence that this procedure is beneficial in terms of polysomnography parameters"
However, it also states that;
"At the same time, high quality evidence indicates no benefit in terms of objective measures of attention and neurocognitive performance compared with watchful waiting"
That looks like quite a mixed picture re success, compared with what you've stated.
The review also specifically states that it can't comment on the benefits for UNDER 5s, like the OP's kid. So am I right that the most up to date Cochrane review doesn't cover this age group?
I'm not an expert by any means, but this does look to me as though the evidence is far more nuanced than you've communicated (and I suppose might explain GP referrals for what your paper described as non-indicated problems).
V happy to stand corrected if I've got that wrong.
