Introduction: This study focuses on the evaluation of postoperative bleeding following conventional tonsillectomies within the Treant Care Group. There is always a certain risk of bleeding after a conventional tonsillectomy, with serious consequences. The aim of this study is to evaluate the observed increase in postoperative bleeding within the Treant Care Group and to investigate potential causes for this increase. Methods: A single-centre retrospective cohort study was conducted in the Department of Otolaryngology at Treant Care Group. 1,198 patients (>11 years) who underwent a conventional tonsillectomy between 1 January 2019 and 1 November 2024, were included. The analysis focused on patient characteristics, surgical techniques, and anaesthesia to evaluate their potential role in the increase in postoperative bleeding. Additionally, a literature study was conducted to supplement the outdated ZATT guideline from 2014. Results: A significant increase in postoperative bleeding was found. The timing of the COVID-19 pandemic and changes to the pain protocol appear to be significantly associated with this increase. Inter-operator differences, male sex and older age were not associated with an increased risk of postoperative bleeding. The literature review suggested that tonsillotomy could be considered for tonsillitis to reduce postoperative bleeding. Furthermore, it could be considered to include Type 2 Diabetes Mellitus as a risk factor in the ZATT guideline. Conclusion: COVID-19 and changes to the pain protocol are significantly associated with the increase in postoperative bleeding following conventional tonsillectomies. However, no definitive conclusions can be drawn because of the overlap in timing of these events.
