OBJECT: Presentation of a 34-year-old pregnant woman with skew deviation due to peripheral vestibular dysfunction caused by herpes zoster oticus. METHODS: A multidisciplinary approach (neuroophthalmology, otorhinolaryngology, neuroradiology) revealed the diagnosis of Ramsey-Hunt syndrome. CASE REPORT: The patient presented with painful herpes zoster vesicles of the left ear, associated with a rotatory vertigo and hearing loss. Otorhinolaryngological examination showed a unilateral peripheral vestibular loss, a nystagmus towards the unaffected right side, no facial nerve dysfunction and a left perception hearing loss, mainly in the frequencies between 2-6 KHz. The patient was treated with Zovirax IV. Neuroradiological examination (MRI without contrast) revealed no abnormalities. Vertical diplopia from skew deviation was noted +/- 10 days after onset of herpes zoster oticus. Neuroophthalmological and orthoptic examination showed a comitant right hypertropia of 6 diopters and a spontaneous nystagmus to the right. CONCLUSION: Skew deviation can be caused by a sudden unilateral cochleo-vestibular loss as described by A.B. Safran. (4,6,7,8).
