Primary tumor was identified on 38% of DLBx and 74% of combined primary and secondary TORS. Only 19% of all cTx patients remained true unknown primary on final pathology (pT0). Demographics and perioperative courses were similar between the two groups. TORS was able to detect primary tumor in the majority of tongue base disease (83%). There were no differences in overall primary tumor size (median 0.8 vs. 1.0\u2009cm), nodal burden, tumor, node, metastasis classification, adjuvant treatment, or 5\u2010year disease\u2010free
