Advances in the diagnosis and treatment of benign paroxysmal positional vertigo.

Abstract

Benign paroxysmal positional vertigo (BPPV) (otolith disease) is the most common neurological and position change related vertigo, accounting for 17–20% of peripheral vertigo. BPPV occur in the elderly. The high incidence age for BPPC was 50 to 70 years and mostly in female. According to the different parts of the lesions, it is divided into anterior canal BPPV (AC-BPPV), posterior canal BPPV (PC-BPPV), horizontal canal BPPV (HC-BPPV). Studies have shown that the incidence of PC-BPPV was 86.36%, the incidence of HC-BPPV was 11.37%, the incidence rate of AC-BPPV was 2.27%. Treatment for PC-BPPV includes manual reduction, drug treatment, psychological treatment, and surgical treatment. Repositioning is the preferred method for the treatment of PC-BPPV with high effective rate and low risk. The mechanism is through the different changes of head position to make the otolith back to utricle. Many manual reduction methods have been reported in clinical treatment of PC-BPPV. With the increasing emphasis on the BPPV, a variety of new methods are being developed and designed.
