OBJECTIVES Tonsillectomy remains one of the commonest operations performed in children. Post-operative diet may affect post-tonsillectomy haemorrhage rate, although post-operative dietary advice varies. We undertook a systematic review of the published literature to assess if and how different post-operative diets were associated with differences in PTH rates following paediatric tonsillectomy, to provide an evidence base to inform individual otorhinolaryngologists' practice and for future guideline development. METHODS A systematic review of the published English literature of the PubMed, Medline and Cochrane Collaboration databases, using search terms used included 'post-tonsillectomy', 'diet', 'dietary advice', 'bleeding', 'haemorrhage', 'paediatric' &'children'. RESULTS Eight publications were included in the review, including 5 randomised controlled trials, 2 case-control studies and 1 cohort study. These involved 1039 patients with 545 patients following a restricted/non-additive diet after tonsillectomy and 494 patients following an unrestricted/additive diet. The average reported PTH rate of patients in the restricted diet groups was 2.3% and 0.8% in patients in the unrestricted diet groups, which is not statistically significant (p = 0.12, one tailed t-test). CONCLUSION PTH following paediatric surgery does not appear to be affected by different post-operative diets or regimes followed by patients. Clinicians should not change the advice provided regarding oral intake and diet following tonsillectomy surgery in children.
