Maxillofacial injuries account for a large portion of emergency department visits and often result in surgical consultation. Although many of the principles of fracture detection and repair are basic, the evolution of technology and therapeutic strategies has led to improved patient outcomes. This article aims to provide a clinical review of imaging aspects involved in maxillofacial trauma and to delineate its relevance to patient management.

ReviewEmergent Neuroimaging During Pregnancy and the Postpartum Period.
Acute neurologic emergencies in pregnancy often require neuroimaging to guide diagnosis and treatment. Implementation of a patient-centered care model in radiology can alleviate a patient's stress, reinforce appropriate imaging workup, improve patient satisfaction, and lead to improved outcomes. The authors present the evaluation, differential diagnosis, and recommended imaging protocols for the three most common acute neurologic symptoms in pregnancy and the postpartum period: headache, seizure, and focal neurologic deficits. With the patient's symptoms as a reference point, the referring physician in consultation with the radiologist can effectively implement the optimal imaging procedures.

ReviewCurrent Challenges in the Use of Computed Tomography and MR Imaging in Suspected Cervical Spine Trauma.
There is controversy regarding the optimal imaging strategy in adult blunt trauma patients for suspected cervical spine trauma. Some investigators recommend negative computed tomography (CT) alone to clear the cervical spine in adult blunt trauma patients, while others insist that MR imaging is necessary, especially among obtunded adult blunt trauma patients. CT is an excellent imaging modality for bony cervical spine injury; however, there is a nonzero rate of clinically significant cervical spine injuries missed on CT. MR imaging has high sensitivity for soft tissue cervical spine injuries, but low specificity for the rare isolated unstable ligamentous cervical spine injury.

ReviewHead and Neck Injuries: Special Considerations in the Elderly Patient.
Traumatic injuries to the head and neck are common in the elderly, which is a rapidly growing sector of the American population. Most injuries result from low-energy falls and therefore might be at risk for delayed presentation and undertriage. Imaging, particularly with computed tomography, plays a vital role in the evaluation of traumatic head and neck injuries in geriatric patients. A thorough understanding of the differing patterns of trauma in the elderly patient and the factors that are associated with poorer outcomes is essential.

ReviewImaging of Submandibular and Sublingual Salivary Glands.
The submandibular and sublingual salivary glands are major salivary glands with a wide spectrum of pathologic conditions. The corresponding spaces along the floor of mouth have complex anatomy, best evaluated with cross-sectional imaging. ⋯ The most common abnormalities in these spaces are inflammatory and infectious, and computed tomography is currently the most common imaging modality used. The anatomy of these spaces is much better depicted with MR; however, all the modalities have their unique roles.
