[Two cases of descending necrotizing mediastinitis].

Descending necrotizing mediastinitis (DNM) is relatively rare inflammatory lesion with high mortality unless an appropriate surgical treatment is undertaken. Recently we successfully treated two surgical cases of DNM. In both cases, the disease started with pharyngeal abscess, and the mediastinal swelling followed. The surgery consisted with neck drainage and the mediastinal drainage through thoracotomy at the same time. A continuous mediastinal irrigation was performed postoperatively, and both patients recovered well. Immediate drainage of the primary lesion and the mediastinum is important once the diagnosis of DNM is established.
