    Computed tomographic (CT) scanning accurately detects head and neck cancer metastases in lymph nodes. CT scans are superior to clinical examination for identifying occult nodal disease, improving preoperative staging.

    Area of Science:

    • Oncology
    • Radiology
    • Head and Neck Surgery

    Background:

    • Computed tomographic (CT) scanning is utilized in preoperative assessments for head and neck cancer.
    • Previous studies suggested CT's utility in evaluating cervical lymphadenopathy, but its accuracy for nodal metastases detection remained unconfirmed.

    Purpose of the Study:

    • To establish the accuracy of CT scanning in detecting nodal metastases in head and neck cancer patients.
    • To compare the diagnostic accuracy of CT scans with clinical staging in preoperative evaluation.

    Main Methods:

    • Fifty consecutive patients with head and neck cancer underwent radical neck dissection and preoperative CT scanning.
    • Clinical staging, CT diagnoses, and pathological findings were correlated.
    • CT scan accuracy was compared against clinical examination accuracy.

    Main Results:

    • The overall accuracy of CT diagnoses in detecting nodal metastases was 90%.
    • CT scanning demonstrated superiority over clinical examination, especially in identifying occult metastases.
    • CT improved the detection rate of metastatic lymph nodes compared to traditional clinical staging.

    Conclusions:

    • CT scanning is a highly accurate tool for preoperative staging of head and neck cancer, particularly for lymph node involvement.
    • CT imaging offers significant advantages over clinical assessment in identifying metastatic disease, aiding in surgical planning.
    • The findings support the routine use of CT scans in the preoperative evaluation of patients with head and neck malignancies.
