Brief summary (from the registry)

Tonsillectomies are frequently followed by severe postoperative pain, hence high analgetics consumption and prolonged hospitalization. Also, postoperative hemorrhages can be hazardous. Constant evaluation of surgical techniques is paramount to improve safety and cost-effectiveness. Frequently tonsillectomies are performed in cold steel technique. Aim of this study will be the evaluation of handling, surgical time, postoperative pain and postoperative hemorrhage rates using the BiZactTM-Device in comparison to traditional techniques on the contralateral side. In one patient, two different techniques will be used. The primary objective will be the surgical time. Regardless of surgeon handedness, surgeons will randomly be assigned to either start with the left or right tonsil, and randomly either to start with the BiZact™ Device or with "cold steel" methods. Additionally, time to stop bleeding, intraoperative blood loss, tonsil mobility, device handling, as well as wound healing will be assessed.
