203 Developing and Fine-Tuning Novel 3D-Printed Biodegradable Scaffolds to Promote Auricular Cartilaginous Regeneration for Surgical Implantation

Abstract

in surgeons' personal lives (98/116) and professional lives (63/116). Most respondees agreed that surgeons have a responsibility to be aware of the environmental impact of surgical services (101/116). Surgeons were generally not aware of any environmental training or education in the workplace and felt efforts towards improving surgical sustainability in their workplace were minimal. Surgeons would welcome more national guidance (103/116) and would welcome more regulation and monitoring (93/116). Conclusions: Our results indicate that surgeons are concerned about climate change and they are willing to engage in efforts to transition to more sustainable practice. 724 Improving the Lives of Patients with Large Amelobastomas In Ethiopia: Long-Term Outcomes of Mandibular Reconstruction for Ameloblastoma Using Non-prognosis are not well described and optimum management remains debated. This study aims to calculate the incidence of CL, identify risk factors, consider effect on patient outcome, and propose a simple management algorithm. Method: This is a retrospective review of all patients who developed CL following PD between January 2006 and April 2020. The following details were obtained from a prospectively maintained database: age, ASA grade, BMI, details of operation, tumour histology, length of stay, and mortality. Results: A total of 560 patients underwent PD and 17 (3.04%) developed CL. These patients had significantly higher BMI (P < 0.01) and significantly longer operation times (P < 0.05). CL patients had a higher rate of portal vein (PV) tumour adherence, PV resection, and intra-operative blood transfusion although this was not statistically significant. Sixteen CL patients (94.1%) were managed successfully with a non-operative approach. Conclusions: 3.04% of patients who underwent PD developed CL. CL was associated with higher BMI and longer operation time. CL did not affect length of stay. The vast majority of CL cases can be managed successfully with a non-operative approach.
