Accurate radiographic evaluation of mandibular fractures

Proper radiographic evaluation is essential to confirm the presence and location of a mandibular fracture. There are several radiographic methods available to evaluate the mandible, including plain film roentgenograms, panoramic tomography and computed tomographic scanning. The plain film radiographs commonly used to evaluate the mandible are the mandiblar series that includes two oblique lateral views a posteroanterior view and Towne s view. Panormanic view is superior to the mandibular series for the diagnosis of mandibular fractures. But, nine cases of mandibular fractures are presented in which a panoramic view failed to demonstrate fractures of the mandible. Therefore, the combination of the mandibular series with the panoramic view provides increased diagnostic information that should enable accurate diagnosis of fractures in all areas of the mandible.
