ObjectiveVestibular neuritis (VN) is an acute, spontaneous, peripheral dizziness that can be accompanied by nystagmus, nausea, vomiting and disturbance of balance, but without cochlear and central nervous system symptoms. The incidence of peripheral vertigo is second only to benign paroxysmal positional vertigox (BPPV) and meniere disease (MD). In recent years, a large number of in vitro, animal, and human studies had shown that serum 25hydroxyvitamin D was involved in the physiological processes of VNregulated inflammation activation, proliferation and differentiation, and immune regulation. The lack of serum 25hydroxyvitamin D was closely related to the pathogenesis of VN.This paper systematically reviewed the relevant literature at home and abroad, which summarized the research progress on the pathogenesis of VN affected by vitamin D deficiency.In this paper, the existing problems in the treatment of VN were proposed,and which was providing new ideas for the diagnosis and treatment of VN in clinical work.
