Deep Neck Infections.

Deep neck infections are less common in the antibiotic era, but when they do occur they remain serious infections. Historically, these infections carried significant morbidity and mortality due to the proximity of the airway, mediastinum, and other vital structures. Deep neck infections were once routinely treated with penicillin, and if infection progressed to abscess, surgical drainage was performed. In recent years the standard medical, surgical, and diagnostic approaches to deep neck infection have changed, and they continue to evolve. Physicians must be aware of these changes to optimally manage patients with deep neck infections.
