Cochrane review: tonsil removal for repeated throat infections

Tonsillectomy or adenotonsillectomy versus non-surgical treatment for chronic/recurrent acute tonsillitis.

Overview

Burton MJ et al.. Cochrane Database Syst Rev 2014 · PMID 25407135 · DOI 10.1002/14651858.CD001802.pub3

Surgery reduced sore throats modestly in the first year (about 0.6 episodes fewer in children); many children get better without surgery.

Does the study support the specific claim? Partly · Methodological quality: high

5. Actual results

Results

Children: 3.0 vs 3.6 sore-throat episodes in first year (difference 0.6; moderate quality); sore-throat days 18 vs 23 (difference 5.1). Less severely affected children had more moderate/severe episodes after surgery (1.2 vs 0.4) counting the postoperative one. Adults: 3.6 fewer episodes (low quality), 10.6 fewer sore-throat days.

Absolute risks

not reported

Authors' conclusion

Modest benefit in children in first year; more severely affected benefit more; insufficient adult evidence; weigh against haemorrhage and pain.

10. Relevance to the specific claim

Shows modest benefit and that many children improve without surgery; partly supports caution (C-ORG-01) but contradicts blanket rejection.

11. Independent contrary findings

12. Transferability to Germany and Europe

Applicable.

13. Overall methodological judgement

Balanced evidence: surgery helps selected patients modestly.
