Imaging Studies

See the list below:

  • The single most informative radiologic study used in diagnosing mandibular fractures is the panoramic radiograph.

    • Panorex provides the ability to view the entire mandible in one radiograph.

    • Panorex requires an upright patient, and it lacks fine detail in the TMJ, symphysis, and dental/alveolar process regions.

  • Plain films, including lateral-oblique, occlusal, posteroanterior, and periapical views, may be helpful.

    • The lateral-oblique view helps in diagnosing ramus, angle, or posterior body fractures. The condyle, bicuspid, and symphysis regions often are unclear.

    • Mandibular occlusal views show discrepancies in the medial and lateral position of the body fractures.

    • Caldwell posteroanterior views demonstrate any medial or lateral displacement of ramus, angle, body, or symphysis fractures.

  • CT scanning may also be helpful.

    • CT scanning allows physicians to survey for facial fractures in other areas, including the frontal bone, naso-ethmoid-orbital complex, orbits, and the entire craniofacial horizontal and vertical buttress systems.

    • Reconstruction of the facial skeleton is often helpful to conceptualize the injury.

    • CT scanning is also ideal for condylar fractures, which are difficult to visualize.
