Descending mediastinitis.

We studied 13 patients with mediastinal abscesses caused by oropharyngeal infections, who presented between April 2007 and June 2011. All patients were operated on after maxillofacial and ear, nose and throat surgeons had treated the primary source and drained all collections in the neck. Thoracic surgery was performed in the same session. Anterior mediastinal collections were drained via a small mediastinotomy. Posterior collections were approached via a thoracotomy. Chest computed tomography was essential to delineate the extent of disease. A thoracotomy approach was used in 7 patients; 2 of them required an anterior mediastinotomy on the opposite side. The others had an anterior mediastinotomy which was bilateral in 2 cases. After repeat computed tomography, 5 patients were operated on for suspected new loculations; tissue edema had caused false imaging in 3 of them. There was no mortality. Early after eradication of the source and pathways to the mediastinum, gravity drainage of mediastinal abscesses, and good antibiotic cover, with repeat computed tomography after 3 days, was an effective approach in this highly fatal disease.
