Pneumomediastinum[Mediastinal emphysema is characterized by the presence of air in the mediastinum, and classified as spontaneous[occurring without obvious cause or secondary[caused by a trauma or artificial ventilation . To study the clinical evaluation of pneumomediastinum, data were obtained from 20 patients. The incidences of spontaneous pneumomedisastinum were 5 and those of secondary pneumomedistinum were 15 cases. The mean age was 21.2$\pm$3.4 years[$\pm$SD in spontaneous pneumomediastinum and 44.1$\pm$20.0 years[$\pm$SD in secondary pneumomediastinum. There were 16 male and 4 female patients. The common presenting compliants were retrosternal pain in 19 patients[95% , dyspnea in 12[60% , and hoarsness in 2[10% . The predisposing factors were asthma,excessive exercise and vomiting in spontaneous pneumomediastinum;trauma, artificial ventilation, tracheostomy, the rupture of trachea or esophagus in secondary pneumomediastinum. The physical findings were subcutaneous emphysema in 17 patients[85% , Hamman`s sign in 11 patients[55% and decreased cardiac dullness in 2 patients[10% . Spontaneous pneumomediastinums were managed conservatively, however, surigical procedures were needed in secondary pneumomediastinums. There was no recurrence, but one patinet died of tension pneumomedistinum. We concluded that spontaneous pneumomediastinum is uncommon, usually benign, and self-limited and secondary pneumomedistinum due to trauma or artificial ventilation is more increasing, and necessitates the early, aggressive intervention.

Hamman 증후군으로 불리기도 하는 종격동기흉은 종격동의 근막내부에 공기가 존재하는 질환이다. 드물지 않게 종격동과 경부 근막 사이의 교통공간을 통해 공기의 확산이 발생할 수 있다. 이런 종격 동기홍의 원인은 기도-기관지 질환 및 식도손상이지만 대부분의 경우에 명확하지가 않다. 몇몇의 증례에서 Macklin효과가 원인으로 알려져 있다. 저자들은 흉부 외상 후 발생한 종격동기흉의 원인으로 전산화단층촬영에서 확인된 Macklin효과의 증례가 있어 이를 보고하고자 한다.

Spontaneous rupture of the pulmonary alveoli after a sudden increase intra-alveolar pressure is a common cause of pneumomediastinum, which is usually seen in healthy young men. Other common causes are traumatic and iatrogenic rupture of the airway and esophagus; however, pneumomediastinum following cervicofacial emphysema is much rarer and is occasionally found after dental surgical procedures, head and neck surgery, or accidental trauma. We present two cases of pneumomediastinum following cervicofacial subcutaneous emphysema after oral trauma. They constitute an uncommon clinical entity, So its radiologic appearance, clinical presentation, and diagnosis are described.

Cervical emphysema and Spontaneous pneumomediastinum is an uncommon disease. Cervical emphysema is mainly caused by trauma or head and neck surgery. Here, we report a case of cervical emphysema and spontaneous pneumomediastinum in a 15-year-old man. This case emphasizes that cervical swelling patients with negative inflammation findings should be scrutinized for cervical emphysema and spontaneous pneumomediastinum.

특징적인 피부병변, 근력약화 등 분명한 피부근염의 임상소견을 보이지 않는 환자에서 동반된 NSIP 치료경과 중 자발성 종격동기종, 피하기종 및 대장기종이 발생한 증례를 경험하였고 스테로이드와 cyclosporin을 사용하여 좋은 치료반응을 경험하였다. 간질성폐렴을 동반한 피부근염에서 자발성 종격동기종, 피하기종 또는 대장기종 등이 드물게 보고되었고 이 경우 나쁜 예후를 보이므로 주의할 필요가 있다. 비교적 드물지만 NSIP에서 종격동기종, 대장기종이 발생하는 경우 임상경과 중 피부근염이 동반 또는 이환되었는지 세심한 관찰이 필요하겠다. 또 NSIP에서 기종이 발견되는 경우 스테로이드와 cyclosporin 또는 다른 면역억제제의 병용투여 등 적극적인 치료가 치료반응과 예후에 좋은 영향을 주리라 사료되어 본 증례를 보고하는 바이다.

Spontaneous pneumomediastinum is a very uncommon entity that is defined as the presence of free air in the mediastinum without an obvious etiology. The presence of air in the spinal canal, known as concurrent pneumorrhachis, is an extremely rare epiphenomenon of spontaneous pneumomediastinum. We report a rare case of spontaneous pneumomediastinum with pneumorrhachis associated with influenza. The patient was diagnosed without invasive procedures, was managed with supportive treatment, and recovered without any complications.

Background: Spontaneous pneumomediastinum is a rare and benign condition that generally occurs in young generations without any precipitating factor or underlying disease. The purpose of this study is to review our experience in dealing with this entity and detail a reasonable course of assessment and management. Methods: From December 1999 to May 2012, 32 spontaneous pneumomediastinum patients were managed in our hospital. We retrospectively reviewed the result of management. Results: Patients ranged in age from 10 to 38 years, with the mean age of $18.3{\pm}5.6$ years. Twenty-five patients were men and seven were women. Initial WBC count was $10,039{\pm}2,993/{\mu}L$ and thirty-one patients underwent computed tomography. Twenty-two patients underwent esophagography and results were shown to be normal. Twenty-five patients were admitted in the hospital and the mean duration of admission was $3.4{\pm}2.0$ days. All patients were managed conservatively and discharged without any complications. Conclusion: Spontaneous pneumomediastinum is a benign condition combined with mild inflammatory signs and secondary causes must to excluded to avoid unfavorable outcomes and select proper management modality.

Mediastinal emphysema, also referred to as pneumomediastinum or Hamman's syndrome, is defined as the presence of air or gas within the fascial planes of the mediastinum. Superior extension of air into the cervicofacial subcutaneous space via communications between the mediastinum and cervical fascial planes or spaces occurs occasionally. The mediastinal air may originate from the respiratory tract, the intrathoracic airway, the lung parenchyma, or the gastrointestinal tract. The presence of air in the mediastinum may be spontaneous, iatrogenic or due to penetrating trauma. Pneumothorax is defined as the presence of air or gas within the pleural cavity. A pneumothorax can occur spontaneously. It can also occur as the result of a disease or injury to the lung or due to a puncture to the chest wall. Pneumomediastinum and pneumothorax is a rare complication of head and neck surgery. Nevertheless, when it occurs, it is usually considered to result from direct dissection by the air at the time of injury or of surgery. Most of the cases of pneumomediastinum and pneumothorax that have been described in the oral and maxillofacial surgery literature result from air dissecting down the fascial planes of the neck. The authors report a case with subcutaneous emphysema, pneumomediastinum and pneumothorax after orthognathic surgery.

종격동기종은 치과 영역에서 매우 드물고 잠재적으로 위험한 합병증이다. 이의 흔한 원인으로는 핸드피스와 고압 공기/물 주사기를 사용하는 발치, 근관치료, 잇몸 밑 치은연하 소파술 등이 있다. 본 증례는 임플란트 식립을 위한 전 치료로 주사기를 이용하여 상악동에 골이식을 시행받은 61세 여자에게서 발생한 대량의 종격동기종과 피하기종의 증례이다. 환자는 치료 도중 갑작스럽게 발생한 구강 통증과 함께 의식 소실이 발생하였고, 응급실로 전원 되었다. 영상학적 검사상 종격동기종과 함께 얼굴과 목부위 전체에 피하기종이 발견되었다. 예방적 항생제, 산소 흡입, 금식 등의 보존적 치료가 이루어졌고, 합병증 없이 7일 만에 퇴원하였다. 환자의 실신은 시술 중 상악동 천공 후 과량의 공기유입으로 인해 발생한 종격동기종에 의해 순간적인 강한 흉부 압박으로 혈압 감소와 통증 쇽에 의한 것으로 생각된다. 치과 치료 중 환자가 의식을 잃었다면 기도 폐쇄의 위험성이 있기 때문에 종격동기종을 즉각적으로 감별하고 치료해야 한다.
