AbstractAbstract PDF
Ramsay Hunt syndrome occurs when the varicella zoster virus reactivates. Classic findings include the triad of facial paralysis, otic pain and herpetic lesions due to the pathogenesis associated with anterograde axonal reactivation of the varicella zoster virus in the geniculate ganglion. In addition to the classic triad, rare features such as a central type of vestibular function test may be observed due to the retrograde spread of the varicella zoster virus from the geniculate ganglion into the brain stem, including involvement of the vestibular nucleus. We present a case of Ramsay Hunt syndrome in a 57-year-old male patients, manifesting not only the typical triad of symptoms but also the unique features associated with brain stem involvement. This presented as direction-changing gaze-evoked nystagmus and a decrease in gain on both sides on video head impulse test. And brain magnetic resonance imaging showed a lesion in the vestibular nucleus of the brain stem.

AbstractAbstract PDF
Facial palsy can be caused by central and peripheral causes, and it can also be caused by brain tumors or infarction. A 59-year-old male, who lost his right hearing 13 years ago due to Ramsay Hunt syndrome, visited our hospital with facial palsy and dizziness. Initial brain diffusion-weighted magnetic resonance imaging (MRI) showed no abnormal findings, and recurrent Ramsay Hunt syndrome or a neoplastic lesion in the internal auditory canal was suspected. After hospitalization, the patient was administered high-dose steroids, and the videonystagmography showed direction-changing gaze-induced nystagmus, so a brain MRI reexamination was scheduled. While waiting for MRI, the patient complained of neurological symptoms such as diplopia, and right lower pontine infarction was diagnosed on MRI. The patient was transferred to the neurologic department and was discharged on the 10th day after conservative treatment. During the 1-year follow-up, pontine infarction did not recur, and neurological symptoms such as facial palsy gradually improved.

AbstractAbstract PDF
Herpes zoster oticus (HZO) is characterized by facial nerve palsy, otalgia and auricular vesicles on the affected side and accepted to be caused by the reactivation of varicella zoster virus (VZV) in the geniculate ganglion. Vestibulocochlear deficits are known to be frequently accompanied by HZO. Unusual clinical manifestations such as only vertigo without facial nerve palsy or hearing loss has been reported. We report a case of 27-year-old man presented with vertigo, sensorineural hearing loss and vesicular eruptions on the left auricle without facial nerve palsy. Serologic test revealed that the patient was positive for immunoglobulin G (IgG) and IgM antibodies against VZV.

AbstractAbstract PDF
Herpes zoster oticus usually accompanies vestibulopathy on the ipsilateral ear. However we have encountered two herpes zoster oticus patients with bilateral vestibulopathies. Bilateral vestibulopathy was detected on the 2nd month and 19th day of herpes zoster oticus, respectively. While the contralateral vestibulopathy was detected 2 month after the ipsilateral vestibulopathy in the first patient, the vestibular function deteriorated simultaneously on the 19th day in the second patient. It seems that the bilateral vestibulopathy was caused by an autoimmune process in both cases, but the initiating event is different. The ipsilateral vestibular damage may have sensitized the immune system in the first patient resulting in sympathetic vestibulopathy. But in the second patient, the ipsilateral cochlear damage may have sensitized the immune system resulting in simultaneous bilateral vestibulopathy. Key words: Herpes zoster oticus, Bilateral vestibulopathy, Autoimmune, Sympathetic vestibulopathy

AbstractAbstract PDF
Herpes zoster oticus (HZO) is characterized by auricular vesicles, facial palsy and vestibulocochlear dysfunction. The 8th cranial nerve can be most frequently involved. Rarely, it may be associated with the involvement of 5th, 6th, 9th, 11th or 12th cranial nerve. However, only few cases of HZO involving vestibular nerve without facial nerve palsy have been previously reported. We experienced an unusual case of 38-year-old woman who presented with auricular vesicles, otalgia, and vertigo of whilrling nature but not with facial palsy. Vestibular evoked myogenic potential (VEMP) and caloric tests that were performed to determine which division of vestibular nerve was involved demonstrated that decreased responses in this case. We report a case of HZO involving superior and inferior vestibular nerve without facial palsy that was confirmed by VEMP and caloric tests with a review of literature.

AbstractAbstract PDF
Herpes zoster oticus (Ramsay Hunt syndrome) is characterized by facial nerve paralysis associated with vesticular eruptions and cochleovestibular symptoms. Many evidences have supported that it is caused by the reactivation of latent varicella-zoster virus in the geniculate ganglion. Recently we experienced a case 49-year-old man presented severe vertigo and a vesicular eruptions of auricle and external ear canal. It is an unusual variant of herpes zoster oticus that involves only vestibular nerve without facial nerve palsy and hearing loss. We believe this case results from reactivation of latent varicella zoster virus in the vestibular ganglion and report with a review of literatures. Key Words: Herpes zoster oticus, Vestibular nerve, Vertigo, Dizziness

AbstractAbstract PDF
Background
: Acute vestibular neuronitis is the disease of which the etiology and pathophysiology are largely unknown . But the viral infection and ischemia of the labyrinth and the vestibular nerve are considered as general etiology. This study was performed to support the viral infection rather than the ischemic theory. Materials & Methods : We studied seventy years old female patient who showed painful vesicles on left auricle and vertigo with spontaneous nystagmus to the right side. We performed physical examination, serologic test, ENG test, pure tone audiogram, brain magnetic resonance imaging and polymerase chain reaction.
Results
: We found small vesicles and vascular injection in left EAC, herpes zoster IgG positive, spontaneous right beating in electronystagmograpy, 54% left canal paresis in Caloric test , decreasing left side Tc in velocity step rotatory test, decresed gain, deviation to left in symmetry and phase lead in sinusoidal harmonic acceleration test, normal range hearing in pure tone audiogram, microangiopathy on cortex in brain MRI and negative PCR.
Conclusion
: This case supports viral infection etiology rather than ischemia in vestibular neuritis. But more studies to find the etiology of vestibular neuronitis are required. Key Words : Herpes zoster oticus, Vestibular neuronitis.
