Abstract

Objectives

This study aimed to investigate the impact of vitamin D deficiency on vestibular function and recurrence in patients with benign paroxysmal positional vertigo.

Methods

This study enrolled 138 patients diagnosed with benign paroxysmal positional vertigo. Vestibular function was evaluated, including ocular vestibular evoked myogenic potentials, cervical vestibular evoked myogenic potentials and caloric tests. Vitamin D levels were recorded.

Results

There was a significant difference in mean vitamin D levels between the normal and abnormal groups of the caloric test, cervical vestibular evoked myogenic potentials, and ocular vestibular evoked myogenic potentials. The likelihood of abnormal vestibular function was lower in patients with normal vitamin D levels than those with deficient levels (< 10 ng/ml). Vitamin D levels were the only predictive factor for recurrence among patients with benign paroxysmal positional vertigo.

Conclusion

A deficiency in vitamin D is more likely to result in abnormalities in the caloric test, cervical vestibular evoked myogenic potentials, and ocular vestibular evoked myogenic potentials in benign paroxysmal positional vertigo patients. The interaction among these factors may contribute to the recurrence.
