Bannister M, et al. - The intention here was to gauge if and how various post-operative diets correlated with variations in the PTH rates following paediatric tonsillectomy. Furthermore, it aimed at illustrating an evidence base to inform individual otorhinolaryngologists' practice and for prospective guideline development. The various post-operative diets or regimes followed by patients did not exert an impact on the PTH following paediatric surgery. Clinicians were recommended against changing the advice provided with regard to the oral intake and diet following tonsillectomy surgery, in children.
