Neumomediastino secundario a fractura aislada de piso de órbita

Introduction: Pneumomediastinum is defined as the presence of air or gas within the fascial planes of the mediastinum. It is usually a phenomenon secondary to traumatic perforations of the aerodigestive tract. Pneumomediastinum secondary to an orbital fracture is a rare event. And it is related to life-threatening complications such as pneumothorax, pneumopericardium and mediastinitis. Aim: To describe a case of pneumomediastinum secondary to an isolated orbital floor fracture and its medical-surgical management. Clinical case: A 42-year-old female patient who suffers trauma to the facial, cervical and thoracic regions, secondary development of a subcutaneous panfacial emphysema and pneumomediastinum, which resolves successfully. Discussion: Pneumomediastinum following an isolated orbital floor fracture is a very rare event. The air can descend along the fascial spaces to the mediastinum. In this sense, blowing your nose is a risk factor to develop this pathology. Conclusion: After a maxillofacial trauma, emphysema of the deep spaces of the head, neck and even the mediastinum can occur.
