5Family history

Diagnostic Methods

  • 1Clinical evaluation of facial weakness
  • 2Electromyography (EMG)
  • 3MRI or CT scan (to rule out stroke or tumor)
  • 4Blood tests

Prognosis

Excellent; 70-85% recover completely within 3 weeks to 6 months. 15-30% have some residual weakness. Higher recovery rates with early corticosteroid treatment. Recurrence in 7-10% of cases.

Prevention

  • No known prevention
  • Prompt treatment of infections

Research Status

Most people recover fully within 3-6 months without treatment. Corticosteroids may improve recovery if started early. Eye protection is crucial to prevent corneal damage. Physical therapy may help. Surgery rarely needed.
