II. Pathophysiology

  1. Dental Infection spread to bilateral submandibular space with rapid progression
  2. Infection displaces the Tongue posteriorly

III. Causes

  1. Dental Infection (Odontogenic infection)
  2. Mandibular Fracture Complication
  3. Tongue or frenulum piercing

IV. Symptoms

  1. Choking sensation (Ludwig's Angina)
  2. Dental Infection or lesion
  3. Facial pain, swelling, redness

V. Signs

  1. Fever
  2. Cellulitis of lower face and neck
  3. Stridor
  4. Trismus
  5. Firm, indurated floor of mouth
    1. Not Ludwig's Angina if this space is soft

VI. Management

  1. Emergent orofacial surgery or otolaryngology Consultation
    1. Surgical debridement if abscess seen on imaging
  2. Airway management
    1. Intubation is typically required to secure the airway
    2. Consider intravenous Dexamethasone to reduce airway impingement
    3. Consider nebulized Epinephrine
  3. Antibiotics: Immunocompetent (2-3 agent protocol)
    1. Metronidazole 500 mg IV every 6 hours and
    2. Penicillin G 3 MUIV q6 hours
      1. If severe, replace Penicillin with Zosyn or Meropenem
      2. Piperacillin-Tazobactam (Zosyn) 4.5 g IV every 6 hours or
      3. Meropenem 1 g IV q8 hours
    3. Add Vancomycin 1 g IV every 6 hours if Staphylococcus aureus infection (presumed MRSA)
      1. Indicated if Gram Stain with Gram Positive Cocci in clusters
  4. Antibiotics: Immunocompromised
    1. Piperacillin-Tazobactam (Zosyn) 4.5 g IV every 6 hours (or Meropenem 1 g IV q8 hours) and
    2. Vancomycin 1 g IV every 6 hours
  5. Antibiotics: Less Severe Infections
    1. Amoxicillin-Clavulanate 875-125 mg orally twice daily every 12 hours
  6. Antibiotics: Penicillin Allergy
    1. Clindamycin 500 mg IV every 6-8 hours

VII. Complications

  1. Airway obstruction
  2. Mediastinal spread via the parapharyngeal space
