Enhanced Communication of Tumor Margins Using 3D Scanning and Mapping

After oncologic resection of malignant tumors, specimens are sent to pathology for processing to determine the surgical margin status. These results are ...

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.

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

Structured light three-dimensional (3D) scanning is a ubiquitous mainstay of object inspection and quality control in industrial manufacturing, and has recently been integrated into various medical disciplines. Photorealistic 3D scans can readily be acquired from fresh or formalin-fixed tissue and have potential for use within anatomic pathology (AP) in a variety of scenarios, ranging from direct clinical care to documentation and education. Methods for scanning and post-processing of fresh surgical specimens rely on relatively low-cost and technically simple procedures. Here, we demonstrate potential use of 3D scanning in surgical pathology in the form of a mixed media pathology report with a novel post-scan virtual inking and marking technique to precisely demarcate areas of tissue sectioning and details of final tumor and margin status. We display a sample mixed-media pathology report (3D specimen map) which integrates 3D and conventional pathology reporting methods. Finally, we describe the potential utility of 3D specimen modeling in both didactic and experiential teaching of gross pathology lab procedures.

Ex vivo 3D scanning and specimen mapping in anatomic pathology.

Given the complex three-dimensional (3D) anatomy of head and neck cancer specimens, head and neck surgeons often have difficulty relocating the site of an initial positive margin to perform re-resection. This cadaveric study aimed to determine the feasibility and accuracy of augmented reality surgery to guide head and neck cancer re-resections.

Augmented-Reality Surgery to Guide Head and Neck Cancer Re-resection: A Feasibility and Accuracy Study.

ASO Visual Abstract: Augmented Reality Surgery to Guide Head and Neck Cancer Re-resection: A Feasibility and Accuracy Study.

Virtual 3D specimen mapping of oncologic surgical specimens provides a visual record of the specimen and margin sampling sites which can be utilized in a variety of cancer care settings. Our objective was to perform a retrospective review of head and neck surgical oncology cases where the specimen was mapped post-operatively and to evaluate the utility of these 3D specimen maps amongst the multidisciplinary cancer care team.

Virtual 3D Specimen Mapping in Head & Neck Oncologic Surgery.

Evaluation of potential gender gaps among Head and Neck (H&N) surgeons can highlight areas for increased support of female H&N surgeons and improve gender diversity within the subspecialty. To evaluate gender trends in representation and career trajectory among recent H&N surgery fellowship graduates.
