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.
