Does diagnostic accuracy of surgeon's perception outweigh frozen section analysis in determining intraoperative clear mucosal surgical margins in oral squamous cell carcinoma patients?

Introduction: The lucrativeness of the frozen section for intraoperative margin assessment in head and neck squamous cell carcinoma is debatable till date. The purpose of this study was to evaluate whether surgeon's perception by gross examination (GE) of margin is an alternative to frozen section.

Aim: The aim was to compare the diagnostic accuracy (DA) of surgeon's perception of tumor-free mucosal and soft-tissue surgical margins intraoperatively assessed by GE and frozen section analysis (FSA).
