Abstract
Spontaneous rupture of the pulmonary alveoli after a sudden increase in int ra-alveolar pressure is a common cause of pneumomediastinum, which is usual ly seen in healthy young men. Other common causes are traumatic and iatroge nic rupture of the airway and esophagus; however, pneumomediastinum followi ng cervicofacial emphysema is much rarer and is occasionally found after de ntal surgical procedures, head and neck surgery, or accidental trauma. We p resent four cases of subcutaneous emphysema and pneumomediastinum with two secondary pneumothoraces after self-induced punctures in the oral cavity. T hey constitute an uncommon clinical entity that, to our knowledge, has not been reported in the literature. Its radiologic appearance, clinical presen tation, and diagnosis are described.
