Ramsay Hunt Syndrome Clinical Presentation

History
A careful history must be obtained in patients with suspected Ramsay Hunt syndrome.
- Patients usually present with paroxysmal pain deep within the ear. The pain often radiates outward into the pinna of the ear and may be associated with a more constant, diffuse, and dull background pain.
- The onset of pain usually precedes the rash by several hours and even days.
- Classic Ramsay Hunt syndrome can be associated with the following:
- Vesicular rash of the ear or mouth (as many as 80% of cases)
- The rash might precede the onset of facial paresis/palsy (involvement of the seventh cranial nerve [CN VII])
- Ipsilateral lower motor neuron facial paresis/palsy (CN VII)
- Vertigo and ipsilateral hearing loss (CN VII)
- Tinnitus
- Otalgia
- Headaches
- Dysarthria
- Gait ataxia
- Fever
- Cervical adenopathy
- Facial weakness usually reaches maximum severity by 1 week after the onset of symptoms.
- Other cranial neuropathies might be present and may involve cranial nerves (CNs) VIII, IX, X, V, and VI.
- Ipsilateral hearing loss has been reported in as many as 50% of cases.
- Blisters of the skin of the ear canal, auricle, or both may become secondarily infected, causing cellulitis.
- Poor prognostic factors for good functional recovery include the following:
- Age older than 50 years
- Complete facial paralysis
- Lack of CN VII nerve excitability
Physical
- The primary physical findings in classic Ramsay Hunt syndrome include peripheral facial nerve paresis with associated rash or herpetic blisters in the distribution of the nervus intermedius.[6]
- The location of the accompanying rash varies from patient to patient, as does the area innervated by the nervus intermedius. It may include the following:
- Anterior two thirds of the tongue
- Soft palate
- External auditory canal
- Pinna
- The patient may have associated ipsilateral hearing loss and balance problems.
- A thorough physical examination must be performed, including neuro-otologic and audiometric assessment.
Causes
- Classic Ramsay Hunt syndrome is ascribed to infection of the geniculate ganglion by herpesvirus 3 (varicella-zoster virus [VZV]).
