Sonography is valuable for staging small tonsil cancers. For larger tumors, especially those risking bone destruction, MRI or CT scans are recommended alongside ultrasound for comprehensive evaluation.

Area of Science:

  • Oncology
  • Radiology
  • Diagnostic Imaging

Background:

  • Tonsil cancers require accurate preoperative staging for effective treatment planning.
  • Sonography offers a non-invasive imaging modality for head and neck assessments.

Purpose of the Study:

  • To evaluate the utility of sonography in the preoperative staging of malignant tonsil tumors.
  • To determine the accuracy of sonography in assessing tumor extent and lymph node involvement.

Main Methods:

  • Retrospective analysis of 36 patients with malignant tonsil tumors.
  • Sonographic evaluation of tumor size, local infiltration, and cervical lymph nodes.

Main Results:

  • Sonography is effective for small tonsil tumors.

  • High accuracy (92-97%) in assessing tongue base infiltration.
  • High accuracy (94%) in detecting cervical lymph node metastasis.
  • MRI or CT recommended for larger tumors with suspected bone destruction.

    • Conclusions:

    • Sonography is a useful tool for staging small tonsil malignancies.
    • Combined imaging modalities (sonography with CT/MRI) improve staging accuracy for advanced tumors.
