Pneumomediastinum (spontaneous, iatrogenic and traumatic) is a relatively uncommon infrequently reported entity. The most common cause is the rupture of marginal pulmonary alveoli, allowing bubbles of air to dissect along the vascular sheaths and connective tissue planes to the mediastinum. Rupture of the trachea or thoracic traumas are other causes of pneumomediastinum. The most common presenting complaint was retrosternal pain, dyspnea, dysphagia, weakness and neck pain. Physical finding revealed: subcutaneous emphysema extended to face, chest or neck, and Hamman's sign. Chest X-ray was made in all cases and diagnosis was completed with chest CT scan and tracheoscopy. We present our series of 34 PM between January 1.1993 to July 31.1995 and discuss about etiology, diagnosis and treatment of this entity.
纵隔气肿（自发性、医源性和创伤性）是一种相对罕见且报道较少的病症。最常见的病因是边缘性肺泡破裂，使气泡沿着血管鞘和结缔组织平面扩散至纵隔。气管破裂或胸部创伤是纵隔气肿的其他病因。最常见的主诉是胸骨后疼痛、呼吸困难、吞咽困难、乏力和颈部疼痛。体格检查发现：皮下气肿扩展至面部、胸部或颈部，以及Hamman征。所有病例均进行了胸部X线检查，并通过胸部CT扫描和气管镜检查完成诊断。我们呈现了1993年1月1日至1995年7月31日期间收治的34例纵隔气肿病例系列，并讨论了该病症的病因、诊断和治疗。
