Han K, et al. - By performing this study in idiopathic benign paroxysmal positional vertigo (BPPV) patients with a different subtype, researchers compared T-score of bone mineral density (BMD) score and serum 25-hydroxyvitamin D level in these patients. Overall 117 consecutive patients with idiopathic BPPV (26 men and 91 women; mean age, 55 ± 11 years; age range, 25 to 78 years) were examined. Of these, 49 had posterior semicircular canal BPPV, 24 had lateral semicircular canal (LSCC) canalolithiasis, and 44 had LSCC cupulolithiasis. Among idiopathic BPPV patients with different subtypes, findings revealed no significant difference in terms of the proportion of osteoporosis/osteopenia or vitamin D deficiency/insufficiency. Among different subtypes of BPPV, either serum level of vitamin D or T-score of BMD was not a distinguishable feature.
