Abstract:
Usual presentations of bilateral vestibular loss are ataxia and oscillopsia. However, fluctuating dizziness is also observed in bilateral vestibulopathy patient. Fluctuating vestibular function in bilateral vestibular loss patients may suggest asymmetric progression of functional loss after compensation is partially accomplished. Because labyrinthine lesion causing vestibular loss is a predisposing factor of benign paroxysmal positional vertigo (BPPV), secondary BPPV can also be developed in bilateral vestibular loss patients. However, BPPV has been hardly noticed in bilateral vestibulopathy patients as a cause of fluctuating dizziness. Authors experienced two cases of BPPV developed in bilateral vestibular loss, one of which showed complete dead labyrinth on ice water caloric test and no significant vestibule-ocular reflex on rotation test. These cases show recurrent BPPV can be the cause of recurrent vertigo in bilateral vestibular loss patients.
