TREATMENT MEDICATIONS  ▪ Antibiotics for severe infections  SURGERY  ▪ Removal of infected tissue if severe  Figure 39.4 An individual with a severe case of gingivitis. The gums are swollen and hemorrhagic. There is visible plaque covering the free gingival margin of both maxillary incisors.  LUDWIG'S ANGINA osms.it/ludwigs-angina PATHOLOGY & CAUSES ▪ Bilateral infection of submandibular space (sublingual, submylohoid)  CAUSES  ▪ Spread from infection of 2nd/3rd mandibular molars, pericoronitis, parotitis, peritonsillar abscess ▪ Mandibular fracture, piercings ▪ Causative agents polymicrobial from mouth ﬂora, dominated by Streptococcus viridans; staphylococci, bacteroides also common  RISK FACTORS  ▪ DM, hypertension, HIV infection, immunosuppression  COMPLICATIONS  ▪ Airway obstruction, mediastinitis, necrotizing cellulitis, sepsis, asphyxia  338 OSMOSIS.ORG  SIGNS & SYMPTOMS ▪ Infection ▫ Fever, chills, malaise, pain ▪ Stiff neck, dysphagia, individual leans forward to expand airway, no lymphadenopathy, bilateral, sudden aggressive spread, enlarged tongue, drooling ▪ Critical symptoms ▫ Stridor, cyanosis ▪ No abscess formation  DIAGNOSIS DIAGNOSTIC IMAGING CT scan ▪ Rule out abscess formation (occurs late in disease) ▪ Chest CT scan ▫ Mediastinitis
