ABSTRACT
Primary nodal drainage basins in melanoma of the head and neck are often unpredictable. The ear is a notorious example of an anatomic site with ambiguous patterns of lymphatic drainage. Preoperative lymphoscintigraphy has recently emerged as one modality to assist in identifying clinically relevant nodes. We propose that the addition of intraoperative lymph node mapping techniques that utilize radioactive tracers ("intraoperative lymphoscintigraphy") can increase the accuracy of identifying sentinel nodes and help to determine which patients may benefit from a complete neck dissection. This report demonstrates the ambiguity in identifying drainage patterns in melanoma of the ear and offers a reliable method of sentinel lymph node mapping. This report also addresses current issues regarding treatment protocols of patients with micrometastatic disease in the periauricular region.
