BackgroundUntreated dental caries or even dental manipulations, such as a tooth extraction, might cause direct spread of an odontogenic infection and consequently the development of life-threatening conditions such as deep neck infections (DNI). The most common source of DNI is of odontogenic origin (38.8-49%). Abscess formation or cellulitis can lead to life-threatening complications, despite new diagnostic imaging technology and widespread availability of antibiotics.ObjectivesTo demonstrate the dangers of DNI, which can create life-threatening situations.MethodsFive cases of DNI of odontogenic origin, which were referred to the oral and maxillofacial surgery unit, are presented.ResultsClinical manifestations included trismus, dysphagia, dysphonia, dyspnea, and infection symptoms. In all cases, computed tomography confirmed diagnosis and extent of abscess. Complications included mediastinitis, respiratory distress, osteomyelitis of the jaws, and in rare cases the mandibular condyle. Treatment included securing the airway, immediate surgical drainage, removal of the infection source, and antibiotic therapy. All patients were discharged in stable and improved condition.ConclusionsDNI treatment on an emergency basis requires proper diagnosis and effective management. To confirm diagnosis and prevent serious complications, it is essential for physicians to recognize the spaces of the head and neck that are likely to be affected by DNI.
