A woman of 71 years suffered from herpes zoster oticus, 7th and 10th nerve paralysis, vertigo and hearing loss; she died after 5 weeks. Neuropathologic examination revealed intensive inflammation in the pons and medulla oblongata and necrotizing arteritis in the cerebello-pontine angle, predominantly on the clinically affected side. The adjacent facial nerve was severely damaged. For the first time, necrotizing arteritis appears as important cause of facial paralysis in the Ramsey-Hunt syndrome.

The purpose of this study is to review etiologies and identify the time-course of vertigo presenting in an ear, nose, and throat clinic, and serve as a reference guide for other clinics. The study includes retrospective chart review in a tertiary care, university hospital. The patient data with reported ICD-10 codes as causes of vertigo between April 2005 and December 2007 were extracted from the database. At each visit, the main diagnosis as to etiology, characteristics of the vertigo, its time-course, and patient demographic data were recorded. Of 547 cases, 17 diagnoses were made in 73.9%. Diagnostic categories included peripheral vertigo 72.9%, central vertigo 0.8%, psychogenic cause 0.2%, and unknown 26.1%. Common causes of vertigo were benign paroxysmal positional vertigo (BPPV) 52.5%, Meniere's disease 14.6%, and sudden idiopathic hearing loss 2.9%. Less common diagnoses were benign paroxysmal vertigo of childhood 0.7%, labyrinthitis 0.7%, and vestibular schwannoma 0.3%. Rare conditions were delayed endolymphatic hydrops, Ramsey Hunt syndrome, otosyphilis, vestibular neuritis, temporal bone fracture, post-concussion syndrome, cerebellar infarction, epilepsy, cervical vertigo, Streptococcus suis meningitis, and psychogenic vertigo. Ninety-nine cases who reported remission of vertigo during the study period had median onset of the remission at 4 weeks. In the ear, nose, and throat clinic at Chiang Mai University, a tertiary university hospital, peripheral vestibular disorders were the main etiology of vertigo. The three most common causes were BPPV, Meniere's disease, and sudden idiopathic hearing loss. Half of the cases who returned for follow up had remitted symptoms within 4 weeks.
