The clinical presentation of Ludwig's angina consists in a severe expanding cellulitis causing swelling of the floor of the mouth, tongue and submandibular region, thus resulting in a possible obstruction of the airway and in a rapid progress in deep neck soft tissue infection and mediastinitis with potentially fatal consequences. Frequently, submandibular cellulitis develops from an acute infection spreading from the lower molar teeth. Mandibular fractures, traumatic laceration of the floor of the mouth, and peritonsillar abscesses are other concomitant clinical features. A case of Ludwig's angina associated with a large erupted odontoma and with a deeply impacted third molar displaced to the border of the mandible is described. The patient was affected by enlargement of submandibular space, marked face swelling causing an evident face deformity, tenderness and redness of the neck and limited movement of the neck and mouth. In the past, Ludwig's angina was frequently fatal, however aggressive surgical and medical therapy have significantly reduced the mortality rate. The reported case can be considered as important, not only because of the rarity of the odontoma eruption in the oral cavity, but mainly for the extent of the clinical manifestation of a lesion usually described in literature as asymptomatic.

Ludwig's angina: a clinical review.

Ludwig's angina is caused by a rapidly expanding cellulitis of the floor of the mouth and is characterized by a brawny induration of the floor and suprahyoid region (bilaterally), with an elevation of the tongue potentially obstructing the airway. In the pre-antibiotic era, Ludwig's angina was frequently fatal; however, antibiotics and aggressive surgical intervention have significantly reduced mortality. We reviewed nine patients with Ludwig's angina between July 1996 and June 2002, all of whom presented with fever, neck swelling, bilateral submandibular swelling and elevation of the tongue. In eight patients (89%) a dental infection appeared to be the underlying cause. High-dosage intravenous antibiotics directed towards the suspected causative microorganisms were given to all of the patients: two were treated successfully with conservative medical management, while seven underwent surgical drainage (a tracheotomy was necessary in one patient). Routine aerobic cultures were done on samples of drained material and the predominant microorganisms were Streptococcus species in two patients; there were none in the other five. Two patients had post-operative complications, but all recovered.
