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

Kayvon F Sharif et al. Laryngoscope. 2023 Aug.

Abstract

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.

Keywords: 3D scanning; 3D specimen mapping; communication; frozen section; head and neck; margin analysis.

Virtual 3D specimen map of an anterior oral cavity composite resection specimen. Labeled white rectangles represent areas of the main specimen where margins were sampled for frozen section analysis (FSA). Red markings represent areas of focal positivity or close (<5 mm) distance to tumor edge determined by FSA.
