“…Spontaneous pneumomediastinum is usually seen in healthy young persons as a result of rupture of peripheral pulmonary alveoli due to a sudden increase of intraalveolar pressure after an exaggerated Valsalva maneuver. [3] Similarly, acute asthma attack, [4] strenous cough, [5] vomiting, [6] rapid vaginal birth, [7] barotrauma, [8] and even cocaine and similar drugs [9] have all been reported to cause pneumomediastinum and subcutaneous emphysema by leading to increased alveolar and intrabronchial pressures. [3,10] Traumatic pneumomediastinum, on the other hand, develops as a consequence of external head, neck, and thoracic traumas as well as iatrogenically with invasive medical procedures such as esophagoscopy, bronchoscopy, endotracheal intubation, and tooth extraction.…”

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 where 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 are very rare occurrences that have seldom been reported. This paper documents a 17-year-old male who presented with diffuse subcutaneous emphysema involving paraorbital facial areas, which extended to neck and mediastinal cavity.
