Subcutaneous emphysema on the head, neck, and pneumomediastinum are, abnomal but well-documented, presence of air in the subcutaneous tissue and mediastinum, and can be diagnosed by palpation of the soft tissues, lateral or crosstable cervical
radiograph and upright chest radiograph.
The commom clinical features of cervical emphysema and pneumomediastinum were facial and cervical swelling, presence of crepitation on palpation of the soft tissue, and retrosternal pain.
Subcutaneous emphysema may arise from use of high-speed air turbine drills, facial trauma, trachea branchial tear, endotracheal intubation, mechanical ventilation, chest injury, tracheostomy, following Lefort I osteotomy, and spontaneously.
Symptoms of subcutaneous emphysema and pneumomediastium are generally self-limiting and eventually subside with conservative therapy.
As we report a case of traumatic subcutaneous emphysema and pneumomediastinum after facial injury with clinical presentation and treatment consideration.
