In many respects, craniofacial trauma in children is akin to that in adults. The appearance of fractures and associated injuries is frequently similar. ⋯ In addition, there are unique aspects that must be considered when imaging the posttraumatic pediatric face. Some of these are based on normal growth and development of the skull base and craniofacial structures, and others on the varying etiologies and mechanisms of craniofacial injury in children, such as injuries related to toppled furniture, nonaccidental trauma, all-terrain vehicle accidents, and impalement injuries.

Over the last two decades, there has been a marked increase in the number of computed tomography (CT) studies performed in the United States, with a resultant increase in the radiation dose delivered to patients. Hence there is an urgent need to optimize CT protocols and to get familiar with the factors affecting the CT radiation dose and with available dose reduction options. This article discusses the basic physics related to CT technique and describes current and future methods of dose reduction. Also briefly described are other CT techniques applicable in the maxillofacial region, such as three-dimensional CT, cone beam CT, and dual-energy CT.

In the clinical assessment of orbital trauma, visual acuity and extraocular muscle motility are critical for rapid evaluation of injury severity. However, assessment of these parameters may be limited by edema and concomitant injuries. ⋯ This review focuses on orbital soft-tissue injuries that can exist with or without orbital fracture. Imaging techniques and soft-tissue injuries, including those involving the anterior chamber, iris and ciliary body, lens, globe, posterior segment, and optic nerve, are reviewed, in addition to intraocular foreign bodies and cavernous-carotid fistulas.
