Pneumomediastinum and pneumothorax from blunt cervical trauma in children.

Abstract

Minor blunt cervical injuries in children are relatively common occurrences leading to serious sequelae in only rare circumstances, yet sufficient impact of even a seemingly minor event may lead to a significant posterior tracheal wall laceration, resulting in pneumomediastinum with or without pneumothorax. Three cases demonstrate how the mechanism of injury does not always match either the severity of initial presentation or the consequent necessary level of emergent management. Pneumomediastinum without pneumothorax often can be treated conservatively; however, the onset of massive pneumomediastinum and pneumothorax may necessitate both tracheotomy and tube thoracostomy as initial treatment.
