What is Ludwig Angina?

Ludwig angina is a rapidly progressive, bilateral cellulitis involving the submandibular, sublingual and submental spaces of the floor of the mouth. It is a life-threatening deep neck infection because the inflammation can elevate and posteriorly displace the tongue, causing airway obstruction. Without prompt intervention, mortality from asphyxiation or sepsis remains significant.

The infection is typically polymicrobial including streptococci, staphylococci, anaerobes (Bacteroides, Fusobacterium) and oral flora. Most cases (70-90%) originate from odontogenic infections of the second and third mandibular molars whose roots extend below the mylohyoid line, allowing direct spread into the submandibular space. Other sources include sialadenitis, oral trauma, mandible fracture and tongue piercing infections.

Symptoms

Bilateral submandibular swelling and induration
Brawny, woody neck with elevation of tongue
Drooling and inability to swallow secretions
Severe trismus (mouth opening difficulty)
Muffled or hot potato voice
Stridor and respiratory distress (late finding)
High fever and toxic appearance
Severe oral pain and dysphagia
Recent dental infection or extraction

Risk Factors

Untreated mandibular molar infections
Recent dental extraction or surgery
Diabetes mellitus
Immunosuppression and malnutrition
Alcohol abuse
Poor oral hygiene
Mandibular trauma or fracture
Sialadenitis or sialolithiasis
IV drug use

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Severe neck swelling with mouth pain (emergency)
  • Difficulty breathing or swallowing saliva
  • Tongue elevation or oral floor swelling
  • Trismus with high fever
  • Voice changes with neck swelling
  • Any neck swelling after dental procedure

Treatment Methods

01
Immediate airway assessment and securing (highest priority)
02
Awake fiberoptic intubation or tracheostomy if needed
03
CT neck with contrast to assess extent and rule out abscess
04
Empiric IV broad-spectrum antibiotics covering anaerobes
05
Ampicillin-sulbactam or piperacillin-tazobactam plus clindamycin
06
Add vancomycin in severe cases or MRSA risk
07
Urgent surgical incision and drainage if abscess present
08
Removal of source dental infection
09
ICU monitoring with airway readiness
10
Dexamethasone consideration to reduce edema
11
Hyperbaric oxygen therapy in severe necrotizing cases

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
