Benign paroxysmal positional vertigo (BPPV) frequently occurs in females over 50 years old, suggesting that a postmenopausal decrease in estrogen secretion might be involved in its onset. An estrogen deficiency is generally known to cause osteoporosis through a reduction in bone mass. This study was designed to investigate a clinical association between idiopathic BPPV and osteoporosis.
We measured the bone mineral density (BMD) at the lumbar vertebrae in 61 patients with idiopathic BPPV who were postmenopausal women over 50 years old using dual-energy x-ray absorptiometry. After being treated with the canalith repositioning maneuver, the patients were followed up for at least 1 year.
Our results showed that the incidence of osteoporosis in patients with BPPV was 26.2%, which was similar to those observed in epidemiological surveys conducted in Japan. However, we found that in BPPV patients with osteoporosis, the incidence of recurrence was 56.3%, which was significantly higher than that observed in patients with normal bone mineral density (16.1%). Furthermore, the frequency of BPPV recurrence increased as BMD decreased.
These results suggest that osteoporosis is a risk factor for BPPV recurrence. The prognosis of BPPV might be clinically predicted by BMD reduction.
