    3. Child Abuse
  3. Signs: Basilar Skull Fracture
    1. Ear findings
      1. Otorrhea
      2. Hemotympanum
    2. Battle Sign (delayed by hours to 24 hours)
      1. Mastoid echymosis
    3. Racoon Eyes (occurs soon after injury)
      1. Periorbital Ecchymosis
    4. Cranial Nerve deficits
      1. Cranial Nerve V (Trigeminal Nerve)
      2. Cranial Nerve VI (Abducens Nerve)
      3. Cranial Nerve VII (Facial Nerve)
      4. Cranial Nerve VIII (Acoustic Nerve)
    5. Double Ring Sign (on bedding, paper)
      1. CSF leakage will form appearance of watermelon in cross section
      2. Large Inner ring of pink, bloody CSF fluid
      3. Small outer ring of clear CSF fluid (analogous to the rind of a watermelon)
    6. Bedside Glucose of draining fluid
      1. CSF fluid will have bedside Glucose >30 mg/dl
  4. Imaging: CT Head (skull films may show some of these findings)
    1. Temporal BoneFracture
      1. Subtle CT findings
      2. Evaluate closely for Epidural Hematoma (from middle meningeal artery injury)
      3. Images
        1. middleMeningealArtery.jpg
    2. Basilar Skull Fracture (CT may be normal)
      1. Intracranial air
      2. Sphenoid Sinus or Frontal Sinus air fluid level
      3. Cribiform PlateFracture
  5. Precautions
    1. Skull Fractures imply injury from a significant force
    2. Skull Fractures increase the risk of intracranial hematomas by 400 fold
  6. Approach
    1. Temporal Skull Fracture
      1. Monitor closely for Epidural Hematoma (from middle meningeal artery injury)
    2. Open or depressed Skull Fracture (>1 bone table width or more than thickness of adjacent skull)
      1. Risk of intracranial hematoma, Brain Contusion and Meningitis
      2. Urgent neurosurgery Consultation
      3. Antibiotics
    3. Occipital Skull Fracture
      1. Associated complications
        1. Subarachnoid Hemorrhage
        2. Contre-coup injury
        3. Posterior fossa hematoma
        4. Cranial Nerve Injury
    4. Stellate or complex Fractures
      1. Consider Child Abuse
    5. Linear non-depressed Fracture
      1. No specific management
    6. Basilar Skull Fracture
      1. CSF Leakage
        1. See Double Ring Sign above
        2. CSF leakage typically resolves within 1 week
        3. No reduction in CSF leak-related Meningitis with prophylactic antibiotics

Skull Fractures (C0037304)

Definition (NCI) A traumatic or pathologic injury to the bones of the skull in which the continuity of the bones of the skull is broken.
Definition (MSH) Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS). Skull fractures may be classified by location (e.g., SKULL FRACTURE, BASILAR), radiographic appearance (e.g., linear), or based upon cranial integrity (e.g., SKULL FRACTURE, DEPRESSED).

Skull Fracture, Basilar (C0748830)

Definition (MSH) Fractures which extend through the base of the SKULL, usually involving the PETROUS BONE. Battle's sign (characterized by skin discoloration due to extravasation of blood into the subcutaneous tissue behind the ear and over the mastoid process), CRANIAL NEUROPATHIES, TRAUMATIC; CAROTID-CAVERNOUS SINUS FISTULA; and CEREBROSPINAL FLUID OTORRHEA are relatively frequent sequelae of this condition.
