Modeling of patient-specific three semicircular canals
The semicircular canals (SCC) are fluid-filled inner ear structures designed to detect circular or angular motion. In this study we modeled three-dimensional biomechanical model of SCC and compared results with real patient case for the Benign Paroxysmal Positional Vertigo (BPPV) disease. The model consists of full 3D fluid-structure interaction incorporating particles, wall, cupula deformation...
متن کاملHierarchical Cluster Analysis of Semicircular Canal and Otolith Deficits in Bilateral Vestibulopathy
Background: Gait imbalance and oscillopsia are frequent complaints of bilateral vestibular loss (BLV). Video-head-impulse testing (vHIT) of all six semicircular canals (SCCs) has demonstrated varying involvement of the different canals. Sparing of anterior-canal function has been linked to aminoglycoside-related vestibulopathy and Menière’s disease. We hypothesized that utricular and saccular i...
متن کاملBilateral vestibulopathy
The author explains the clinical presentation, pathophysiology, prevention, diagnostic work-up, and management of bilateral vestibulopathy. Gait ataxia and oscillopsia are the key clinical features of bilateral vestibulopathy. Other clinical features of bilateral vestibulopathy include absence of spontaneous vertigo and nystagmus; inability to walk in the dark or on uneven or soft surfaces, unl...
متن کاملThe dimensions and sensitivities of semicircular canals.
With this definition it is possible to compare the mechanical sensitivities of all semicircular canals. For this purpose three different approaches seem feasible. (1) The effect of growth of one particular semicircular canal on G in one species. (2) Comparison of values of G for the three semicircular canals in one species. (3) Comparison of values of G of the horizontal canal in different spec...
متن کاملVestibular function in severe bilateral vestibulopathy.
OBJECTIVES To assess residual vestibular function in patients with severe bilateral vestibulopathy comparing low frequency sinusoidal rotation with the novel technique of random, high acceleration rotation of the whole body. METHODS Eye movements were recorded by electro-oculography in darkness during passive, whole body sinusoidal yaw rotations at frequencies between 0.05 and 1.6 Hz in four ...
