## Executive Summary & Key Highlights
Since 1992, the approach to melanoma surgery has shifted from elective lymph node dissection to sentinel node biopsy, due to advancements in treatment methods.
## In-Depth Reporting & Editorial Analysis
Since 1992, melanoma surgical treatments have evolved significantly. In the context of a clinically negative nodal basin, the traditional elective lymph node dissection has largely been replaced by sentinel node biopsy (SNB). This new approach is followed by complete lymph node dissection if SNB results indicate positivity upon histopathological analysis. Numerous studies have explored various aspects of these techniques, particularly examining factors like micro-metastases vs. macro-metastases, SNB tumor burden, and the number of positive or excised non-sentinel lymph nodes.
