3. CT Scan
A CT scan is ideal when visualization is difficult, especially visualization
of the condylar head and high condylar neck. CT is generally the
preferred method of imaging for multiple mandibular fractures, and is
especially helpful in the multiply traumatized patient requiring images
of the cervical spine, cranium, and carotid arteries. Also, 3-D CT
scanning capabilities add immeasurably to the diagnosis and treatment
planning of complex facial fractures.
4. MRI Scan
Magnetic resonance imaging (MRI) is better for evaluating soft-tissue
disease, such as hematoma and complications of trauma.
5. Occlusal View
An occlusal view will show symphysis fractures.
6. Periapical Radiographs
Periapical radiographs show dental root fractures next to mandible and
alveolar fractures.
