ABSTRACT
Deep neck infections are charts potentially dangerous though of low incidence. Few times linked to severe complications, as mediastinitis, of high morbi-mortality. They call for emergency procedures combining neck and thorax surgery, if there is a mediastinitis, with a broad-spectrum antibiotherapy within an Intensive Care Unit, with the aim of the maintain the patients's equilibrium constant till their reestablishment.

Nevertheless the pending severity all three survived. We emphasize the necessity of realizing the pressing surgery and the utilitarianism of broad-spectrum antibiotherapy as key elements in order to get the patient's reestablishment.
