[Severe cervical skin and soft tissue infections and necrotizing fasciitis].

Cervical severe skin and soft tissue infections and necrotizing fasciitis originate from dental or pharyngeal infections. When compared to other forms of skin and soft tissue infections, they are recognized late, usually after one week of evolution often in a patient receiving antibiotic treatments. Extensions toward adjacent anatomical structures including mediastinum lead to a life-threatening prognosis. The cutaneous appearance of these severe infections is usually inflammatory cervical signs combined to facial oedema. These moderate clinical signs require immediate surgery after CT scan imaging.
