“…These measurements have generally involved laser Doppler techniques (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25), which cannot resolve the blood supply to specific cochlear regions, such as the stria vascularis (8) or basilar membrane (1), that are implicated in forms of sensorineural hearing loss. Ultrasound and magnetic resonance imaging are poorer still in this regard and, although unable to resolve cochlear blood flow directly, have revealed clinical correlations between hearing loss and intracranial circulatory disruptions outside the cochlea (7,(26)(27)(28). Approaches based on injection of either radioactive or labeled microspheres into the bloodstream can allow inferences on the differences in blood flow between cochlear areas (1,18,29).…”

Aims-We sought to develop techniques for visualizing cochlear blood flow in live mammalian subjects using fluorescence microendoscopy.Background-Inner ear microcirculation appears to be intimately involved in cochlear function. Blood velocity measurements suggest that intense sounds can alter cochlear blood flow. Disruption of cochlear blood flow may be a significant cause of hearing impairment, including sudden sensorineural hearing loss. However, inability to image cochlear blood flow in a nondestructive manner has limited investigation of the role of inner ear microcirculation in hearing function. Present techniques for imaging cochlear microcirculation using intravital light microscopy involve extensive perturbations to cochlear structure, precluding application in human patients. The few previous endoscopy studies of the cochlea have suffered from optical resolution insufficient for visualizing cochlear microvasculature. Fluorescence microendoscopy is an emerging minimally invasive imaging modality that provides micron-scale resolution in tissues inaccessible to light microscopy. In this article, we describe the use of fluorescence microendoscopy in live guinea pigs to image capillary blood flow and movements of individual red blood cells within the basal turn of the cochlea.

“…[2][3][4][5][6]15 SSNHLV is a disease of multifactorial etiology, with vertebrobasilar obstructive disease as one of the main causes. The variability in the prevalence of this condition (1.2 to 21%) is probably due to the different age groups studied; an association between SSNHLV and vertebrobasilar obstructive disease is expected to be more likely among the elderly.…”

Sudden sensorineural hearing loss and vertigo (SSNHLV) has multifactorial causes, of which viral, autoimmune and vascular insufficiency are the most common. The therapeutic management for SSNHLV includes antiviral drugs, corticosteroids, vasodilators, normovolemic hemodilution therapy and hyperbaric oxygen therapy. Vertebrobasilar occlusive disease and carotid occlusive disease are seldom related to SSNHLV. Discussions concerning SSNHLV caused by occlusive vascular disease are important and necessary for both neurologists and otolaryngologists, since their therapeutic management and prognosis are very different from other causes of hearing loss and vertigo. Here, we present our experience with three cases managed with interventional treatment and conduct a review and discussion on the relevant literature. We conclude that investigation of vertebrobasilar and carotid occlusive diseases is necessary in patients over 50 years of age who present SSNHLV, mild neurological symptoms and a history of arteriosclerosis, high blood pressure or thrombosis.
