摘　　要：All paediatric tonsillectomies were examined from 2012–2019 at a single tertiaryreferral institution,and all were performed by one of two paediatric otolaryngologists.One exclusively used the diathermy,the other exclusively used the Coblator II.Two Coblator units were purchased simultaneously in 2012 and not replaced.There was no significant difference in number of tonsillectomies performed(1298 via diathermy,1221 via Coblator),nor in postoperative day of bleed,patient age,indication for procedure,and no patient had an underlying coagulopathy.The most common indication for tonsillectomy in both groups was sleep-disordered breathing.There was no significant difference in postoperative haemorrhage rates between groups for the first six years of the study(0%-1.4%/year).Years 7 and 8 saw the Coblator group haemorrhage rate significantly increase(0%-0.6%diathermy group vs 2%-3%Coblator group),though still fell within accepted rate of postoperative haemorrhage.The devices were then replaced,and the differences in haemorrhage disappeared.There appears to be a significant increase in paediatric post-tonsillectomy haemorrhage when using a Coblator device greater than six years old.This may suggest a useful lifespan for the Coblator II device.
