Brief Summary

Post-tonsillectomy hemorrhage (PTH) is a feared complication to tonsillectomy. Tonsillectomy may be performed using different surgical techniques, which include both "cold" and "hot" dissection and hemostasis - but the technique may have a great impact on the risk of PTH. As of today there is no standard on how to perform hemostasis during tonsillectomy in Denmark. The aim of this study is to clarify whether cold dissection with either cold or hot hemostasis during the surgical procedure of tonsillectomy holds the lowest risk of PTH. Secondary objective is to address whether there is a difference in pain perception associated with the two procedures. The null hypothesis is that there is no difference in PTH between cold and hot hemostasis in tonsillectomy.
