Treatment of Benign Paroxysmal Positional Vertigo

...what are its anatomical causes and how can it be treated?

This article aimed to review some of the most common Particle Repositioning Maneuvers (PRM) and investigate their effectiveness. These common maneuvers are used to treat either the horizontal, the anterior, or the posterior semicircular canal. These canals can cause dizziness. 

This article highlights the effectiveness of the Epley Maneuver, the Reverse Epley Maneuver, and The Barbecue Roll Maneuver for treatment.

The authors of this study found that the vast majority of participants (70%) were negative for symptoms following two bouts of re-testing, and 81% were negative by the end of the 30-day study. The authors state that repositioning maneuvers were clinically significant and effective in treating BPPV, but that the right test and assigned maneuver needs to be determined. On testing, it was found that the PSC BPPV was most common (73.5%), followed by the HSC BPPV (22.5%). It was also found that a small amount (3.3%) had multi-canal involvement. Only 1% were positive for ASC BPPV. This can be important to keep in mind as the assessor in a clinical practice. While the PSC was the most prevalent in this study, it is important to thoroughly screen for all three of the semi-circular canals so a correct diagnosis and treatment plan can be made.
