The application of panoramic zonography to the diagnosis of maxillofacial fractures.
Traditionally, multiple radiographic views and techniques were required to elucidate the nature and extent of fractures of the maxillofacial complex. As a result, patient cost in terms of time, expense, manipulation, and radiation exposure scaled upward. Synthesis and interpretation of the fragmented bits of information from multiple films also constituted a labor-intensive process. A new imaging modality, panoramic zonography, provides precise anatomic imaging of preselected areas of interest with minimal radiation exposure. The usefulness of this technique in the diagnosis, treatment, and follow-up of traumatic events in the mandibular and maxillofacial regions is illustrated by a series of cases.
