Raccoon Eyes (Periorbital Ecchymosis) from Blunt Forehead Trauma

Bilateral periorbital ecchymosis (raccoon/panda eyes) with supraorbital laceration and forehead abrasions — classic external signs of basilar skull fracture.

Pathophysiology

What Raccoon Eyes Signify

Initial Assessment & Stabilization

1. Primary Survey (ATLS Protocol)

• Airway — protect if GCS ≤ 8 or airway at risk
• C-spine immobilization — mandatory until cleared; associated cervical injury must be excluded
• Neurological status — GCS, pupils (size, reactivity, symmetry), focal deficits

2. Immediate Red Flags Requiring Urgent Neurosurgical Consultation

• GCS < 14 or deteriorating level of consciousness
• Unequal or blown pupil
• CSF rhinorrhoea (clear watery nasal discharge — confirm with β₂-transferrin assay)
• Signs of raised intracranial pressure (Cushing's triad: hypertension, bradycardia, irregular respirations)
• Coagulopathy or anticoagulant use

Investigations

Management

A. Conservative (Most Anterior Fossa Fractures Without Complications)

• Bed rest with head elevated 30–45°
• Strict avoidance of nose-blowing, sneezing with open mouth, straining (Valsalva maneuver) — prevents pneumocephalus and CSF leak exacerbation
• Analgesia — paracetamol preferred; NSAIDs and aspirin avoided (bleeding risk)
• Monitor neurological status closely; repeat CT if deterioration

B. CSF Rhinorrhoea Management

1. Conservative first — most CSF leaks from anterior skull base settle spontaneously within 7–10 days with bed rest and head elevation
2. Lumbar drain — if leak persists beyond 7–10 days, reduces CSF pressure and allows dural healing
3. Endoscopic endonasal repair — definitive treatment for persistent or recurrent CSF leaks; bony defect identified on high-resolution CT and patched (fat, fascia, mucosal flap ± synthetic material)
4. Open craniotomy — reserved for large defects not amenable to endoscopic repair

C. Prophylactic Antibiotics

• Controversial — routine prophylactic antibiotics for basilar skull fracture are not recommended by most guidelines (Cochrane evidence shows no reduction in meningitis; may select resistant organisms)
• Treat established meningitis or sinusitis aggressively if it develops

D. Surgical Indications (Neurosurgical)

• Epidural/subdural hematoma with mass effect
• Depressed skull fracture over anterior fossa
• Persistent CSF leak (>10–14 days) or recurrent meningitis
• Significant pneumocephalus (tension pneumocephalus is a neurosurgical emergency)
• Optic canal fracture with visual compromise — decompression may be considered

E. Ophthalmological Management

• Rule out traumatic optic neuropathy, retrobulbar hematoma, globe injury
• Retrobulbar hematoma causing orbital compartment syndrome: lateral canthotomy + cantholysis is an emergency procedure

F. The Raccoon Eyes Themselves

• No specific local treatment is required for the periorbital ecchymosis per se — it resolves spontaneously over 2–3 weeks
• Cold compresses in the first 24–48 hours may limit spread
• The ecchymosis is a sign, not the primary problem; management targets the underlying injury

Complications to Monitor

Key Takeaway

1. Ruling out life-threatening intracranial injury (CT head urgently)
2. Detecting and managing CSF leak (β₂-transferrin, conservative vs. endoscopic repair)
3. Preventing infectious complications (meningitis, abscess)
4. Neurosurgical and ophthalmological consultation based on findings

Raccoon Eyes from Blunt Forehead Trauma — Without Skull Fracture

Understanding the Mechanism

• Trauma ruptures small subcutaneous and periorbital vessels in the forehead/supraorbital region
• Blood tracks downward by gravity through loose areolar tissue of the eyelids (which has virtually no resistance)
• It pools in both periorbital regions, producing bilateral ecchymosis
• The orbital septum confines the blood, giving the characteristic circumferential "raccoon" appearance

Confirming the Absence of Fracture

Management of Soft-Tissue Raccoon Eyes (No Fracture)

1. Immediate Phase (0–48 hours)

• Ice/cold compresses applied intermittently (20 min on, 20 min off) — reduces ongoing extravasation, limits ecchymosis spread and swelling
• Head elevation (30°) — reduces dependent pooling of blood in periorbital tissue
• Rest — avoid straining, bending forward
• Analgesia — paracetamol; avoid NSAIDs and aspirin (antiplatelet effect worsens bleeding)

2. Subacute Phase (48 hours–2 weeks)

• Warm compresses after 48 hours — promotes vasodilation and reabsorption of the hematoma
• Gentle massage (after 48–72 hours) — aids lymphatic drainage
• No patching or occlusion of the eye is necessary unless there is corneal/conjunctival injury

3. Eye Care

• Ophthalmology review if:
  • Visual acuity is reduced
  • Diplopia (suggests orbital floor blow-out or extraocular muscle injury)
  • Subconjunctival hemorrhage extending posteriorly (may indicate orbital fracture)
  • Proptosis or restricted eye movements
• Routine lubricating eye drops if periorbital swelling causes incomplete lid closure (exposure keratopathy risk)

4. Associated Forehead Laceration (if present)

• Clean and irrigate wound thoroughly
• Repair in layers under local anaesthesia within 24 hours
• Debride only frankly necrotic tissue — the face has rich blood supply and heals well
• Tetanus prophylaxis as appropriate

5. Patient Education

• Inform the patient the discolouration will worsen for 48–72 hours before improving — this is normal tracking of blood, not a sign of progression
• Full resolution expected in 2–3 weeks
• Return immediately if: vision changes, headache worsens, any clear nasal discharge, vomiting, or drowsiness develop

Natural History

Key Points

• Without skull fracture, raccoon eyes are a benign self-limiting soft tissue condition
• No specific treatment accelerates resolution significantly — management is supportive
• The priority remains excluding intracranial and orbital injury before labelling it as purely soft tissue
• No antibiotics, no surgery, no steroids are indicated
• Ophthalmology referral is only needed if ocular symptoms are present
