Characterization of Cervicofacial Lymphnodes - A Clinical and Ultrasonographic Study

Lymph nodes undergo reactive changes in response to a wide variety of stimuli, the most common cause being inflammatory and immune reactions, apart from primary malignant neoplasms and metastatic tumours. It is well accepted that a clinical examination alone cannot be considered diagnostic to justify the involvement of cervicofacial lymph nodes especially deep and small nodes. Ultrasonography is an easy, reproducible, non invasive, non-ionizing imaging modality to evaluate cervicofacial lymph nodes.
