Recent advances in idiopathic bilateral vestibulopathy: a literature review
Abstract Background Idiopathic bilateral vestibulopathy (IBV) is an acquired bilateral peripheral vestibular dysfunction of unknown etiology, with persistent unsteadiness but without sensorineural hearing loss (SNHL) other than age-related hearing loss (ARHL). Main text The prevalence of IBV is unkn...
