Skull fracture

This page is for adult patients; for pediatric patients see Skull fracture (peds)

Background

• Presence of skull fracture significantly increases risk of underlying intracranial injury

Clinical Features

Linear skull fracture

• Often no physical exam findings

Depressed skull fracture

• Depression may be palpable on physical exam

Basilar skull fracture

• Raccoon eyes
• Battle sign
• Hemotympanum
• Clear rhinorrhea or ottorhea may indicate CSF leak from dural tear associated with fracture

Differential Diagnosis

Head trauma

• Traumatic brain injury
  • Intracranial hemorrhage
    • Intra-axial
      • Traumatic intracerebral hemorrhage
    • Extra-axial
      • Epidural hemorrhage
      • Subdural hemorrhage
      • Subarachnoid hemorrhage
  • Moderate-to-severe traumatic brain injury
    • Elevated intracranial pressure
  • Mild traumatic brain injury

Evaluation

• CT head
• CBC
• Coags

Management

Linear Skull Fracture

• If no intracranial bleed or other injuries, observe for 4-6 hrs and discharge
  • Patients with advanced age, coagulopathy, or other co-morbidities may benefit from admission

Depressed Skull Fracture

• Neurosurgery consult
• Antibiotics, seizure prophylaxis, surgery/wound debridement may be indicated in discussion with a neurosurgeon

Basilar Skull Fracture

• Neurosurgery consult
• Antibiotic prophylaxis is often started in setting of CSF leak but should be discussed with a neurosurgeon

Disposition

• Admit - except for simple linear skull fracture with no other injuries
