Abstract

Ludwig’s Angina (LA) is a rare but rapidly evolving form of toxic cellulitis with heavy clinical symptoms and the potential of a rapid spread to adjacent cervical triangles. possible expansion. Although the diagnosis of Ludwig's angina is more clinical, ultrasound is a necessary complementary examination to delineate the extent of the inflammation and to highlight its most common complications, such as obstruction of the airway, abscess formation, osteomyelitis and vascular clots which are indications for more immediate treatment. The use of ultrasound for evaluating the extent of the condition is not often reported (and it is reported as isolated case reports) in the literature which allows for a high end and detailed estimation of the infection and its surrounding tissues. This case series describe the USG features examination of and highlights the importance of USG imaging of spreading infections caused by dentomaxillofacial pathologies.
