Enhanced Intraoperative Communication of Tumor Margins Using 3D Scanning and Mapping: The Computer-Aided Design Margin.

We have implemented a novel intraoperative communication system for head and neck surgical pathology using 3D scanning technology and computer-aided design (CAD) software. Here, we highlight our CAD margin protocol, in which we 3D scan head and neck oncologic surgical specimens and map frozen section results. This enhances the communication of margin status between surgeons and pathologists and delivers visual anatomic guidance for re-resection when needed. Laryngoscope, 133:1914-1918, 2023.
