Treatment for Bell's Palsy

First-Line Treatment

  • The American Academy of Otolaryngology-Head and Neck Surgery recommends prescribing oral corticosteroids within 72 hours of symptom onset for all patients 16 years and older with Bell's palsy 1, 2
  • A recommended regimen is a 10-day course with at least 5 days at high dose using either Prednisolone 50 mg daily for 10 days or Prednisone 60 mg daily for 5 days followed by a 5-day taper 1, 2

Combination Therapy Considerations

  • The American Academy of Otolaryngology-Head and Neck Surgery does not recommend antiviral monotherapy for Bell's palsy treatment 3, 4
  • Combination therapy with oral antiviral therapy and corticosteroids within 72 hours of symptom onset may be considered as an option 4
  • One study showed higher complete recovery rates with combination therapy (96.5%) compared to steroids alone (89.7%) 4

Special Considerations

  • Current guidelines do not provide specific recommendations based on CRP levels for Bell's palsy treatment 1, 5, 6
  • For children, evidence for steroid use is less conclusive as children show higher rates of spontaneous recovery than adults 2, 3

Follow-up and Monitoring

  • Reassess or refer to a facial nerve specialist if new or worsening neurologic findings develop, ocular symptoms develop, or incomplete facial recovery persists 3 months after initial symptom onset 7, 8
  • Implement eye protection for patients with impaired eye closure 8

Common Pitfalls to Avoid

  • Delaying treatment beyond 72 hours reduces effectiveness of therapy 2
  • Using antiviral therapy alone is ineffective and not recommended 3, 4
  • Failing to rule out other causes of facial weakness before diagnosing Bell's palsy 9, 7
  • Not providing adequate eye protection for patients with impaired eye closure, which can lead to corneal damage 8
  • Routine laboratory testing and imaging are not required for typical presentations of Bell's palsy 7
