title: [Pneumomediastinum, a rare complication secondary to a minor maxillary fracture].
abstract: METHODS
  A pneumomediastinum was discovered fortuitously on a CT scan prescribed to a patient for facial and cranial trauma. Emphysema was attributed secondarily to an anterolateral maxillary wall fracture. The evolution was favorable after simple clinical and radiological surveillance.
  
  
  CONCLUSIONS
  The observation of a pneumomediastinum should first be related to a tracheal or esophageal wound with a severe prognosis. Endoscopy under general anesthesia was not necessary for our patient thanks to CT scan with 3D reconstruction. There is no consensus for systematic antibioprophylaxis.
