title: [Pneumomediastinum Due to the Fracture of the Maxillary Antrum].
abstract: A 47-year-old man was admitted to the emergency room, half a day after having fallen down on his right cheek drunkenly onto a concrete block. Physical examination revealed that the contusion was limited to the right side of his face, only around the cheek, without trauma to the neck, chest or abdomen. But wide ranging tactile crepitus with severe swelling was present on his face and neck due to widely spread emphysema. Computed tomography (CT) scan revealed some fractures of maxillary antrum, facial and cervical emphysema spreading to the lower part of mediastinum. After a conservative treatment, he recovered without any severe systematic complication. It was found that the facial and cervical emphysema and pneumomediastimum completely disappeared on the follow-up CT scan, 18 days after the event.
