The computer-aided design margin: Ex vivo 3D specimen mapping to improve communication between surgeons and pathologists

Head Neck. 2023 Jan;45(1):22-31. doi: 10.1002/hed.27201. Epub 2022 Sep 26.

Abstract

Background: Numerous challenges exist in determining surgical margin status. Communication between surgeons and pathologists is crucial for specimen orientation and accurate margin assessment.

Methods: A prospective study to determine feasibility of incorporating three-dimensional (3D) scanning into surgical pathology workflow was performed. A structured-light 3D scanner captured the photorealistic surface topography of fresh surgical specimens. Computer-aided design (CAD) software was used to document sites of margin sampling and sectioning. Surveys were distributed among faculty and staff stakeholders to assess feasibility.

Results: A series of 40 cases were 3D-scanned. Median image acquisition time was 8 min. The majority of respondents agreed that the experimental 3D system helped achieve clearer communication. 3D specimen maps assisted in the communication of a focally positive or close margin in 4 of 17 cases.

Conclusions: Routine 3D scanning and specimen mapping is feasible and represents an innovative approach to intraoperative and final pathology documentation, margin analysis, and surgeon-pathologist communication.

Keywords: 3D printing; 3D scanning; frozen section analysis; head and neck cancer; pathology communication.
