Indications for ultrasonography in parotid pathologies.

J N Bruneton, M Sicart, P Roux

    Summary

    Ultrasonography effectively differentiates benign from malignant parotid tumors, serving as a primary diagnostic tool for parotid region swellings. CT scans are recommended for suspected malignant lesions to assess deep extension.

    Area of Science:

    • Radiology
    • Otolaryngology
    • Medical Imaging

    Background:

    • Salivary gland tumors, including parotid tumors, represent a significant clinical challenge.
    • Accurate initial assessment is crucial for appropriate patient management and treatment planning.

    Purpose of the Study:

    • To define the role of ultrasonography in evaluating salivary gland pathologies, specifically parotid tumors, adenopathies, and parotitis.
    • To assess the efficacy of ultrasonography in differentiating benign from malignant parotid tumors.

    Main Methods:

    • Retrospective analysis of 141 parotid tumors, 21 parotid region adenopathies, and 22 cases of parotitis.
    • Application of specific ultrasonographic criteria for lesion characterization.
    • Correlation of ultrasonographic findings with subsequent diagnostic imaging (CT scan) and histopathology.

    Main Results:

    • Ultrasonography demonstrated a sensitivity of 79.8% in differentiating benign from malignant parotid tumors using defined criteria.
    • Ultrasonography is proposed as the initial imaging modality for parotid region tumefactions.
    • CT scans are essential for evaluating the extent of malignant lesions identified by ultrasonography.
    • Ultrasonography is not recommended for diagnosing parotitis or lithiasic pathologies.

    Conclusions:

    • Ultrasonography is a valuable, sensitive tool for the initial evaluation of parotid tumors, aiding in the distinction between benign and malignant types.
    • For suspected malignant parotid lesions, ultrasonography guides the need for further investigation with CT scans.
    • Ultrasonography has limited utility in the diagnosis of parotitis and salivary gland stones.
