Treatment for Ramsay Hunt Syndrome in a 79-Year-Old Woman

The recommended treatment for Ramsay Hunt syndrome in a 79-year-old woman is a combination of antiviral therapy (acyclovir 800 mg five times daily or famciclovir 500 mg three times daily) and oral corticosteroids (prednisone 60 mg daily) for 7-10 days, started as early as possible after symptom onset. 1

Pathophysiology and Clinical Features

• Ramsay Hunt syndrome is caused by reactivation of varicella-zoster virus (VZV) in the geniculate ganglion, resulting in facial nerve palsy accompanied by vesicular rash on the ear (zoster oticus) or in the mouth 1
• Common associated symptoms include tinnitus, hearing loss, nausea, vomiting, vertigo, and nystagmus due to the close proximity of the geniculate ganglion to the vestibulocochlear nerve within the bony facial canal 2, 1
• Patients with Ramsay Hunt syndrome often have more severe facial paralysis at onset and are less likely to recover completely compared to those with Bell's palsy 1

First-Line Treatment

1. Antiviral Therapy:

   • Acyclovir 800 mg five times daily for 7-10 days 1, 3
   • OR Famciclovir 500 mg three times daily for 7-10 days 1
   • Treatment should be initiated as soon as possible, ideally within 72 hours of symptom onset 4, 3

2. Corticosteroid Therapy:

   • Prednisone 60 mg daily for 3-5 days 1
   • Corticosteroids reduce inflammation and edema of the facial nerve 3

3. Combined Therapy:

   • The combination of antiviral and corticosteroid therapy has been shown to improve recovery rates of facial nerve function compared to corticosteroids alone 3
   • In one study, complete recovery of facial nerve function was achieved in 90% of patients treated with combined acyclovir and steroids, compared to only 64% with steroids alone 3

Treatment for Non-Responders or Severe Cases

• For patients not responding to standard oral therapy, consider intravenous high-dose methylprednisolone 5
• This approach has shown benefit even when administered as late treatment in patients with poor prognostic factors 5
• Patients with multiple cranial nerve involvement may particularly benefit from aggressive treatment 6

Supportive Care and Follow-up

• Audiometric evaluation should be performed at the conclusion of treatment and within 6 months to assess hearing recovery 7
• Eye protection is essential if facial weakness prevents complete eye closure
• Patients with residual hearing loss and/or tinnitus should be counseled about possible benefits of audiological rehabilitation 7

Prognostic Factors

• Negative prognostic factors include:
  • Advanced age (particularly relevant for a 79-year-old patient)
  • High-grade facial weakness at presentation
  • Absence of R1 and R2 response on blink reflex test
  • Delayed initiation of treatment 5

Special Considerations for Elderly Patients

• Monitor for potential side effects of corticosteroids, including:
  • Elevated blood glucose
  • Hypertension
  • Electrolyte imbalances
  • Increased risk of infection
• Adjust dosing if necessary based on renal function and comorbidities
• Consider prophylaxis for gastrointestinal protection during corticosteroid treatment

Early diagnosis and prompt initiation of combined antiviral and corticosteroid therapy are crucial for optimal outcomes in elderly patients with Ramsay Hunt syndrome 4, 3.
