Background:
Tissue preservation and tumor clearance are hallmarks of Mohs micrographic surgery, but no standardized method currently exists to guide trainees on how to balance the two.
Objective:
The authors provided residents and fellows with additional histologic information to enhance their surgical decision-making without changing the standard methodology of Mohs surgery.
Methods And Materials:
Trainees were provided initial biopsy slides (IS) and frozen vertical sections (VS) of the first Mohs layer. All Mohs layers were excised in standard fashion, and vertically oriented sections were taken from the layer without disturbing the surgical margins to obtain VS. Surveys were used to assess trainees' confidence in performing Mohs surgery with and without these tools.
Results:
Trainees reported increased confidence in performing Mohs surgery when they reviewed IS before surgery and viewed VS of the first layer.
Conclusion:
Reviewing IS and VS improved trainees' confidence in performing Mohs surgery. This additional histological information was obtained while maintaining the usual steps of Mohs surgery. Objective information obtained from IS and VS may explain why trainees' confidence increased using this technique. Both IS and VS can be valuable teaching tools that may enhance trainees' ability to perform Mohs surgery.
