Background

  • Also know as "Ramsay Hunt syndrome"
  • Acute peripheral facial neuropathy associated with erythematous vesicular rash of the skin of the ear canal, auricle, or mucous membrane of the oropharynx
  • Associated facial paralysis usually involving CN VII but may involve CN VIII
    • geniculate ganglion: movements of the facial muscles, sensation of parts of the ear and ear canal, taste function of the tongue, and lubrication of the eyes and oral mucosa
    • vestibulocochlear nerve is close to the geniculate ganglion, patients may complain of tinnitus, hearing loss, and vertigo
  • Caused by herpes zoster

Clinical Features

Ear findings and facial droop classic for Ramsey Hunt Syndrome.
  • URI symptoms common for 1-3 days prior
  • Paroxysmal pain deep within ear: radiates outward into the pinna of the ear[1]
    • Usually precedes the rash by several hours and even days
    • Erythema and Swelling of auricle
    • Vesicles within external ear canal and on auricle
  • Facial pain
    • Develop over 3-7 days

Differential Diagnosis

Facial paralysis

Ear Diagnoses

External

Internal

Inner/vestibular

Varicella zoster virus

Evaluation

  • Otoscopy
  • Neuro exam focusing on Cranial nerve, crossed findings, upper and lower motor neuron involvement

Management

Most effective when started within 3 days of symptom onset

Disposition

  • Outpatient primary care follow-up

Prognosis

  • Poor prognostic factors for good functional recovery include[3]
    • age older than 50 years
    • complete facial paralysis
    • lack of CN VII nerve excitability
