[Suppurative abscess-forming mediastinitis after tooth extraction. Consequences for therapeutic approach].

Purulent mediastinitis is a rare but serious complication of a descending odontogenic infection with a high mortality. Diagnosis is difficult and frequently delayed. Physical examination is often nondiagnostic, but may include pronounced edema of the neck and chest. CT scan is the single most important tool for early diagnosis. The treatment is always is surgical, in combination with an extremely high dose of combined antibiotics. Ultimately, we only could save our patient with this therapy.
