Introduction:
Documenting orientation of resection specimens in head and neck surgery can be challenging.
Purpose:
The primary objective of this study was to investigate an enhanced documentation method for orientation of the resection specimen.
Methods:
A feasibility study was conducted to explore the potential of using a 3D scanner to improve documentation of the orientation of the resection specimen. 3D scans of the resection specimen were registered on a CT-based 3D model of the patient's original anatomy, resulting in 3D models of the resection specimen in the correct anatomical position and orientation.
Results:
The scanning, orientation, and verification processes are explained in detail.
Conclusion:
This innovative approach for documenting the orientation of resection specimens can improve the understanding of precise anatomical locations of close or positive margins. This understanding is crucial for determining the necessity and precise location of adjuvant therapy, minimising adverse effects and lowering the risk of local recurrence.
