A dangerous cause of airway obstruction: deep neck infection

Abstract

Deep neck infection (DNI) is an infection in the fascial spaces of the neck. Complications of DNI, including mediastinitis, internal jugular vein thrombosis, and upper airway obstruction, are severe and potentially life threatening. Therefore, early identification and accurate management of DNI are essential. We review the anatomy of the deep spaces of the neck to determine the route of DNI spread so that emergency doctors, physicians, and otorhinolaryngologists can quickly recognize the development of lethal complications of DNI, such as asphyxia from airway obstruction.
