    An updated CT scan protocol aids in diagnosing parapharyngeal space masses, reducing the need for angiography. This imaging approach achieves high diagnostic accuracy, improving preoperative planning for patients.

    Area of Science:

    • Radiology
    • Head and Neck Surgery
    • Oncology

    Background:

    • Parapharyngeal space masses present diagnostic challenges.
    • Accurate preoperative diagnosis is crucial for effective surgical planning and patient outcomes.

    Purpose of the Study:

    • To develop and evaluate an updated CT imaging protocol for parapharyngeal space masses.
    • To assess the diagnostic accuracy of the proposed CT protocol.

    Main Methods:

    • Retrospective analysis of CT and surgical data from 104 patients with parapharyngeal space masses.
    • Implementation and evaluation of a dynamic CT scanning protocol.

    Main Results:

    • The updated CT protocol achieved a specific preoperative diagnosis in 88% of cases.

  • A limited differential diagnosis, including the final diagnosis, was possible in nearly all cases.
  • Dynamic CT scanning obviated the need for diagnostic angiography or digital venous imaging (DVI) in most patients.

    • Conclusions:

    • The developed CT protocol significantly enhances preoperative diagnostic accuracy for parapharyngeal space masses.
    • Dynamic CT scanning is a valuable tool, potentially replacing conventional angiography in evaluating these lesions.
    • The study provides evidence for the origin of minor salivary gland benign mixed tumors.
