Ludwig angina is a dreaded infection involving the sublingual, submandibular, and submental spaces. Its pathogenesis is most often related to an odontogenic infection gaining access to these spaces and thereby creating a clinical scenario manifested by painful swelling in the floor of the mouth, tense edema and induration of the submental soft tissues, and progressive elevation and posterior displacement of the tongue. The pain and trismus, along with the swelling of the oral and cervical tissues and tongue displacement, create a severely compromised airway.
