• Orbital emphysema is a rare complication of orbital and facial trauma, involving the sinuses and occasionally the nasal cavity. Most cases occur as a result of trauma but spontaneous orbital emphysema has been reported. Clinical manifestations are often delayed until the upper airway pressure increases as when blowing or coughing. Along with the fracture, the rupture of the underlying mucosa is essential for emphysema to manifest. We report a 29-years-old male who consulted in the emergency room due to eyelid swelling after a Valsalva maneuver, a couple of hours after suffering a facial injury secondary to a fall. In the presence of eyelid emphysema, the patient underwent craniofacial imaging studies, confirming an ethmoidal lamina papyracea fracture.
