Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Ludwig angina is defined as rapidly spreading bilateral cellulitis of the submandibular and sublingual spaces with associated tongue elevation. A characteristic painful, brawny induration is present in the involved tissue. The posterior mandibular molars are the usual odontogenic origin for the infection. Streptococcus, Staphylococcus, and Bacteroides species are the most common pathogens. Affected individuals are typically 20 to 60 years old, with a male predominance. Patients are usually febrile and may demonstrate impressive trismus, dysphonia, and odynophagia. Dysphagia and drooling are secondary to tongue displacement and oropharyngeal swelling. Potential airway compromise or spread of infection to the deep cervical layers and the mediastinum is possible.
