[Post-traumatic pneumomediastinum (not associated with pleuro-mediastinical organ's lesion). Two cases (author's transl)].

The authors of this article describe two cases of post-traumatic pneumomediastinum, without pneumothorax and oesophageal or bronchial mucosal lesions. Both cases had a benign evolution. General considerations are discussed and the authors concluded that when pneumomediastinum is not associated with lesions of mediastinical organs no surgical treatment is usually required.
