Pneumomediastinum is air leakage to mediastinal space from various potential sites, including lung, esophagus, trachea, and neck. It is a rare condition that develops either spontaneously with increased intraalveolar or intrabronchial pressure, or due to trauma. Although cases with face or neck trauma with subcutaneous emphysema that extended to mediastinal cavity via anatomical connections in face and neck have been reported, orbital traumas leading to pneumomediastinum is a very rare occurence that that has only been reported in a few reports. This paper reports a 17-year-old male who presented with diffuse subcutaneous emphysema involving paraorbital, facial areas, which extended to neck and mediastinal cavity from there.
