Virtual 3D Specimen Mapping in Head & Neck Oncologic Surgery

Abstract

ObjectivesVirtual 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.MethodsA retrospective review of our 3D specimen model biorepository was performed. Surgical specimens were 3D scanned and then graphically annotated (or “mapped”) during routine pathologic processing. The resulting 3D specimen maps were distributed to the multidisciplinary oncologic care team. Final margin status and any use of the 3D specimen maps were recorded.ResultsA total of 28 cases were included. Virtual 3D specimen maps were utilized by the cancer care team in 8 cases (29%), including 2 positive margin cases, 2 close margin cases, and 4 indeterminate margin cases. 3D specimen maps were used to visualize positive margin sites for pathologist‐surgeon communication as a visual reference during tumor board discussions and to inform radiation treatment planning.ConclusionPost‐operative virtual 3D specimen mapping of oncologic specimens creates a permanent visual record of the specimen and the margins sampled and may serve as a beneficial tool for communication amongst the multidisciplinary cancer care team.Level of EvidenceLevel 4 Laryngoscope, 2023

The art of specimen orientation: Two‐dimensional maps for oropharynx squamous cell carcinoma

“…New studies explore the use of intraoperative scanning of specimens to build a 3D computer-generated map for specimen orientation. [9][10][11] Unlike these methods, however, which require an intraoperative 3D scanner and designated personnel, our 2D maps are standardized and easily adapted to the surgeon and pathologist workup with minimally added time and tools.…”
