Facial Infection & Swollen Neck Glands: What You Need to Know

A large infected facial wound can cause cervical lymphadenopathy via lymphatic drainage.

Pathophysiology

1. Bacterial inoculation → local inflammation → cytokine/chemokine release.
2. Lymph carries antigens/dendritic cells to regional nodes (submandibular, upper cervical).
3. Nodes enlarge due to lymphoid hyperplasia, edema, immune cell influx.
4. Nodes become tender, mobile, warm.

Red Flags for Complications

• Fixed, hard, matted nodes → malignancy or deep space infection.
• Overlying skin erythema/fluctuance → nodal suppuration.
• Systemic toxicity (fever >39°C, tachycardia, hypotension) → sepsis.
• Airway compromise (submandibular swelling → Ludwig's angina).

Management

• Wound care: debridement, culture, appropriate antibiotics.
• Warm compresses to nodes.
• Monitor for progression; imaging (US/CT) if deep extension suspected.

Facial infections drain to "danger triangle" (via facial vein → cavernous sinus)—monitor for orbital/central signs.
