Submandibular Space Infection
A deep space infection of the floor of the mouth and submandibular region, most commonly of odontogenic origin, with the severe form known as Ludwig's angina.
Full Definition
Submandibular space infection refers to cellulitis or abscess formation in the fascial spaces below the mandible and floor of the mouth. The most frequent source is an infected lower second or third molar. When the infection spreads bilaterally to the submandibular, submental, and sublingual spaces simultaneously, the condition is termed Ludwig's angina—a potentially life-threatening emergency causing airway compromise. In editorial contexts, 'Ludwig's angina' retains the possessive apostrophe-s and is capitalised as an eponymous term. Editors must not confuse 'angina' in this context with cardiac angina pectoris.
Usage
Usage note: Retain the possessive form 'Ludwig's' with apostrophe. Clarify that 'angina' here means choking/strangling (Latin), not cardiac pain. Flag any use that conflates the two conditions.
