Benign paroxysmal positional vertigo（BPPV）is a common peripheral vestibular disorder，and at present，otolith shedding and displacement is highly recognized as the main pathological mechanism of BPPV. An increasing amount of evidence has shown that otolith particle shedding is closely associated with vitamin D，and 25-（OH）D is expected to become a potential biomarker for BPPV and an important target for the treatment of BPPV and residual symptoms after successful repositioning. This article reviews the pathophysiological mechanism of vitamin D in BPPV and residual dizziness and summarizes the association of vitamin D with BPPV and residual symptoms based on the treatment methods for vitamin D regulation.
