Abstract Background The current standard of documenting and communicating frozen section margin results is inefficient. We present a novel method of generating 3D digital models of gross tumor specimens to more clearly visualize histopathological margin results. Methods Fifty‐five head and neck specimens were scanned and virtually “inked” using 3D software. These 3D specimen maps were displayed in the operating room to provide the surgeon with a real‐time specimen‐to‐defect relationship by which further resections could be guided. Results Margin results were reported within an average of 34 min using the proposed workflow. The scanner rendered accurate models of specimens that exceeded 3.0 × 3.0 × 3.0 cm. Critical specimen features to consider were size, color, textural complexity, and the presence of discernible anatomic landmarks. Conclusions Optical 3D scanning technology can improve the quality of head and neck margin documentation and the efficiency with which results are communicated between the pathologist and surgeon.
