Abstracts

Generally, 5 mm is a standard clear and free excised margin at the oral cavity. However, regarding the application of conservative surgical approaches and acceptable outcomes gained by postoperative adjuvant therapies, it is necessary to consider a lesser margin in distinct subsites. Besides these factors, heterogeneous anatomical features influencing surgical margins could have been under-discussed. For example, the early stage of buccal mucosa cancer is less likely to invade deep structures and rarely spread behind the muscular and fascial planes. In addition, the cortical bone of jaws may play an anatomical blockage tumor invasion. Therefore, a conceptual surgical approach is introduced that utilizes surrounding anatomic structures as a natural margin that forms a barrier to gaining more significant functional and resected outcomes. Conclusively, the idea of a “standard clear margin” could be questioned by surgeons. Therefore, we should reconsider an optimal standard resection margin that is the relevancy of anatomicopathological features in oral cavity cancer.
