    Summary
    This summary is machine-generated.

    Realtime sonography is an effective, noninvasive tool for staging oral and oropharyngeal tumors, complementing orthopantomography. It accurately defines tumor characteristics and bone invasion, aiding diagnosis of primary and recurrent diseases.

    Area of Science:

    • Radiology
    • Oncology
    • Diagnostic Imaging

    Context:

    • Oral cavity and oropharyngeal tumors require accurate staging for effective treatment.
    • Orthopantomography is a standard imaging technique for these regions.
    • Realtime sonography offers a noninvasive adjunct for detailed soft tissue and bone assessment.

    Purpose:

    • To evaluate the utility of realtime sonography as an adjunct to orthopantomography for staging oral and oropharyngeal tumors.
    • To assess the accuracy of sonography in defining tumor characteristics, relationship to bony structures, and cortical invasion.
    • To compare preoperative sonographic and orthopantomographic findings with intraoperative and histopathological results.

    Summary:

    • 109 patients with oral/oropharyngeal tumors underwent 123 orthopantomography and realtime sonography examinations.

  • Sonography accurately defined tumor size, shape, structure, and relation to bone.
  • The method demonstrated high sensitivity for detecting cortical invasion and periosteal reaction, correlating well with surgical and pathological findings.

    • Impact:

    • Realtime sonography is a valuable, noninvasive, and cost-effective diagnostic tool for oral and oropharyngeal tumors.
    • It enhances the diagnostic capabilities of orthopantomography, particularly in assessing bone involvement.
    • Understanding sonography's limitations, such as potential false positives post-procedure, is crucial for accurate interpretation.
