Emergency pediatric ear, nose, and throat imaging

Pediatric ear, nose, and throat emergencies broadly comprise infection, trauma, and airway obstruction secondary to a multitude of etiologies. Imaging occupies center stage in the diagnosis of many of these conditions and their complications, making it imperative for radiologists and other physicians covering the pediatric emergency department to familiarize themselves with the imaging appearances of these entities. Toward this goal, this article describes the imaging features of common pediatric ear, nose, and throat emergencies. Differential considerations, potential fallacies, and complications have been discussed when appropriate. Because a sound knowledge of the most relevant, efficient, time, and cost-effective imaging modality is of undisputable value in the acute setting, the preferred modality for each specific condition has been outlined. Finally, in alignment with our commitment to using radiation judiciously, we have suggested using ultrasonography and magnetic resonance instead of computed tomography, where possible, to optimize cost-benefit ratio for our young patients.
