Fig. 11 displacement of otoliths and
cupula
In this study, a mechanism that maintains equilibrium and the information delivered to
the brain in vestibular apparatus is checked. A quantitative simulation model which
considers the change in pressure of the endolymph by the otolith moving in BPPV is
suggested. Our work has been focused on activities in semicircular canal rather than
obtaining an accurate solution. This basic research will be helpful for developing more
efficient treatment about benign paroxysmal positional vertigo. In future work, the 3D
model based on CT image will be developed with more accurate materials properties of
the whole structure. Also three semicircular and cochlea coupling analysis will be
carried out to give more realistic simulation results.
