The etiology of benign paroxysmal positioning vertigo (h-BPPV) of the horizontal semicircular is unknown. Insight was obtained from two patients with h-BPPV and associated hearing impairment. Based on the different inner ear lesion patterns in neurolabyrinthitis contrary to ischemic labyrinthine infarction we assessed multiple vestibulo-cochlear functions for the first time in two patients who suffered from h-BPPV with sudden unilateral hearing loss. While in patient no. 1 the lesion pattern (posterior canal paresis in addition to the sudden hearing loss) could possibly be caused by ischemia of the common cochlear artery, the lesion pattern of patient no. 2 (hearing loss and ipsilateral paresis of the posterior and horizontal semicircular canal) exceeds the typical vascular labyrinthine territories and may indicate viral neurolabyrinthitis.

The purpose of the study was to evaluate prevalence, characteristic symptoms, and management of Chiari Malformation 1 (CM1). A retrospective chat review was made in Otology Tertiary Department including 439 otologic patients referred to the Helsinki University Hospital Radiology Department for head magnetic resonance imaging (MRI) during 2005 and also among 42 patients seen at the Department of Neurosurgery in years 2001-2005 with a diagnosis of CM1. We made a structured analysis of medical records focusing on patient history, neurologic symptoms, and radiologic findings. For surgical patients, information was collected on symptoms, treatment, and operative outcome. The prevalence of CM1 in the 439 otologic patients was 0.9%. Most CM1 patients sent to the Neurosurgery Department were operated on. Two months postoperatively, 26 patients (68%) had benefited from the surgery, but 12 patients (32%) experienced no change to symptoms. The possibility of CM1 should be borne in mind in patients presenting with atypical benign positional vertigo or recurrent facial paresis.
