Change in mean postoperative pain in patients undergoing tonsillectomy with cold water versus usual practice: A pragmatic trial.

In this trial, we report a reduced pain score at all days of observation in the intervention group. Irrigation of the tonsillar fossa is a safe, cost-effective, and less technically demanding technique that could be employed to reduce postoperative pain. Further studies with randomization, blinding and a larger sample size could further improve on our results.
