Enlarged lymph nodes in head and neck cancer: Analysis with triplex ultrasonography.

Background: Presence of cervical metastasis is one of the factors influencing the outcome of patients with carcinoma of the head and neck, its early detection is potentially very important. Triplex ultrasonography technology have definitive role in detecting clinically undetectable involvement of lymph nodes (LNs). The purpose of this study was to evaluate, whether triplex ultrasonography characterization of cervical LNs could, with an acceptable degree of certainty, differentiate malignant from benign/reactive LNs, in order to prevent invasive diagnostic procedures.
