ABSTRACT

Ludwig's angina is a rare, life-threatening deep neck space infection involving the bilateral sub-mandibular and sublingual spaces, often caused by dental infections. This case highlights a 30-year-old male with uncontrolled type 2 diabetes and poor oral hygiene who presented with neck swelling, fever, pain, dysphagia, and respiratory distress. Physical examination revealed submandibular swelling, tenderness, and dental caries. Laboratory findings confirmed elevated ESR and Streptococcus viridans as the causative organism. Prompt treatment included airway management, broad-spectrum antibiotics (metronidazole and ampicillin), surgical drainage, and supportive care, which improved clinical outcomes. Ludwig’s angina requires timely diagnosis and treatment to prevent complications like airway obstruction, sepsis, and respiratory collapse. Most cases stem from odontogenic infections, with Streptococcus and Staphylococcus species being common pathogens. Effective management includes airway stabilization, incision and drainage, and targeted antibiotics based on culture sensitivity. Clinicians must maintain a high index of suspicion for Ludwig's angina in patients with dental infections and bilateral submandibular swelling to ensure prompt and lifesaving interventions.
