Introduction: Ludwig angina consists of a severe infectious inflammatory process, involving the sublingual and submaxillary spaces. It is generally odontogenic in origin and is characterized by firm tumefaction, diffuse, bilateral, and painful. It mainly occurs in men, young, and healthy people and has a polymicrobial nature. The patient presents fever, drooling, dysphagia, odynophagia, and trismus may also manifest with progressive respiratory obstruction, due to the supraglottic edema and dyspnea. Treatment with empirical therapy is done with antibiotics, surgical drainage with placement of Penrose drains, and maintenance of the upper airway. It can develop complications such as mediastinitis, bubpherenic abscess, pericardial and/or pleural effusion, empyema, osteomyelitis of the mandible, the carotid sheath infection, and suppurative thrombophlebitis of the internal jugular vein.
