Ludwig’s Angina

Ludwig’s Angina is a rapidly progressive, potentially life-threatening form of cellulitis involving the submandibular, sublingual, and submental spaces. Characterized by bilateral involvement, it often originates from dental infections and carries a high risk of airway obstruction due to the upward and backward displacement of the tongue.

Most cases (up to 90%) arise from odontogenic infections, particularly of the second or third mandibular molars. It is typically a polymicrobial infection involving both aerobic and anaerobic bacteria, most commonly Streptococcus, Staphylococcus, and Bacteroides species.

The infection spreads through the fascial spaces of the floor of the mouth. Because these spaces are continuous, the infection rapidly progresses bilaterally. The accumulation of pus and inflammatory edema leads to "woody" induration of the submandibular region, elevating the tongue against the soft palate and narrowing the oropharyngeal lumen.

It predominantly affects adults in their 30s to 60s, though it can occur at any age. There is a slight male predilection. Incidence is higher in populations with limited access to dental care.

Poor oral hygiene, dental caries, recent tooth extraction, trauma to the floor of the mouth, diabetes mellitus, malnutrition, and immunocompromised states (e.g., HIV/AIDS, chemotherapy).

A. Early Symptoms

• Fever


• Malaise


• Dental pain


• Mild neck swelling B. Common Symptoms


• Drooling


• Dysphagia (difficulty swallowing)


• Odynophagia (painful swallowing)


• Neck stiffness


• Floor of mouth swelling C. Advanced Symptoms


• Trismus (lockjaw)


• Dyspnea (difficulty breathing)


• Stridor


• Muffled voice ("hot potato" voice) D. Emergency Symptoms


• Cyanosis


• Agitation/Confusion (hypoxia)


• Complete airway obstruction

Inspection reveals bilateral submandibular swelling, elevated tongue, and drooling. Palpation demonstrates a characteristic "woody," firm, non-fluctuant induration. Vital signs often show tachycardia and tachypnea.

A. Clinical Assessment: Primarily diagnosis based on history and physical exam.
B. Laboratory Testing: CBC and inflammatory markers.
C. Imaging Studies: CT scan with contrast is the gold standard.
D. Functional Tests: Pulse oximetry.
E. Biopsy Findings: Generally not indicated.
F. Genetic Testing: Not applicable.
G. Differential Diagnosis: Angioedema, epiglottitis, retropharyngeal abscess.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: Assess for infection
Expected Findings: Leukocytosis with left shift
Interpretation: Suggests systemic inflammatory response

Contrast-enhanced CT Neck: Essential for defining the extent of space involvement and identifying potential abscess collections versus diffuse cellulitis.

Angioedema (lacks fever/pain), Epiglottitis (involves supraglottic structures), Retropharyngeal abscess (posterior to the pharynx), or deep neck space tumors.

Airway obstruction (most lethal), sepsis, mediastinitis, carotid sheath involvement, and aspiration pneumonia.

A. Lifestyle Modifications: Not applicable.
B. Preventive Measures: Excellent dental hygiene and routine oral checkups.
C. Medical Treatment: High-dose intravenous broad-spectrum antibiotics (e.g., Ampicillin-Sulbactam or Clindamycin).
D. Surgical Treatment: Incision and drainage of the submandibular space.
E. Interventional Procedures: Fiberoptic-guided intubation or emergency tracheostomy.
F. Rehabilitation: Speech and swallowing therapy.
G. Emergency Management: Airway protection is the absolute priority.

Good if identified early and treated aggressively. Mortality has significantly decreased with modern antibiotics and airway management.

Early treatment of dental caries and abscesses; management of underlying systemic metabolic disorders.
