Summary
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.
