We evaluated patients with oral tongue cancer suffering from recurrence, which develops in the intervening area between the primary site and the neck. Lesions in the area around the greater cornu of the hyoid bone (‘para-hyoid’ area) involve the hypoglossal nerve and the root of the lingual artery and often extend to the parapharyngeal space, resulting in treatment failure and death. This area is beyond the limits of neck dissection. We assume that metastases in occult lymph nodes along the lingual artery might be responsible for such lesions, though the clinical importance of these small nodes in cancer therapy has been underestimated so far. Once a para-hyoid lesion becomes clinically evident, salvage may appear to be difficult even with radical surgery using a microvascular free-tissue flap. We believe that a dissection of occult nodes along the lingual artery, which correspond to the draining course of the lateral lingual nodes, should be included intraoperatively in any type of neck dissection (elective or therapeutic) for patients with oral tongue cancer. This could be the key to improving the regional control rate of patients with small oral tongue cancer.
