Cervical lymph node metastasis in oral squamous carcinoma preoperative assessment and histopathology after neck dissection

摘要

The presence or absence of nodal metastasis has a great impact on the prognosis and survival of patients with head and neck cancer. The risk of occult metastasis is related to the method by which the lymph nodes are evaluated. It is possible to reduce the risk of undiagnosed metastasis with accurate imaging techniques and thus probably reduce the number of elective neck treatments.
