    High-resolution real-time sonography accurately detects cervical lymph node metastases in head and neck cancers, outperforming palpation. This imaging modality is crucial for preoperative staging and identifying complications like venous thrombosis.

    Area of Science:

    • Oncology
    • Radiology
    • Medical Imaging

    Context:

    • Head and neck cancers often metastasize to cervical lymph nodes, complicating treatment and prognosis.
    • Accurate staging of lymph node involvement is critical for effective head and neck cancer management.
    • Traditional palpation has limitations in detecting small or deep lymph node metastases.

    Purpose:

    • To evaluate the diagnostic accuracy of high-resolution real-time sonography for cervical lymph node staging in head and neck cancers.
    • To compare sonography's effectiveness against clinical palpation in detecting metastases.
    • To assess sonography's utility in identifying associated complications, such as internal jugular vein thrombosis.

    Summary:

    • High-resolution real-time sonography demonstrated 89% accuracy in detecting cervical lymph node metastases, surpassing palpation's 80% accuracy in 118 histologically confirmed cases.

  • Sonography identified internal jugular vein thrombosis in 9 patients and provided insights into tumorous infiltration of arterial vessel walls in 12 patients.
  • The study highlights sonography's unique ability to resolve imaging artifacts, ensuring reliable staging.

    • Impact:

    • Sonography offers superior diagnostic accuracy for cervical lymph node staging in head and neck cancers compared to palpation.
    • Preoperative sonographic evaluation is recommended for all patients with malignant head and neck tumors to guide surgical and treatment planning.
    • This modality aids in detecting critical vascular complications and improving the overall management of head and neck malignancies.
