Near infrared spectroscopy (NIR) in combination with indocyanine green (ICG) dye can assist surgeons in determining lymph node groups which are likely affected by metastatic cutaneous squamous cell carcinoma of the head, face and neck in real-time based on an individual patient's lymphatic anatomy. NIR ICG can identify aberrant lymphatic drainage routes which may cause metastatic disease to arise in unexpected areas. NIR mapping can help to inform the magnitude of surgery required and guide less-invasive clearance procedures in patients at high risk of perioperative morbidity and mortality.
