“BPPV with the most common variant (crystals in the posterior SCC) can be treated successfully — with no tests, pills, surgery or special equipment — by using the Epley maneuver.

This simple, effective approach to addressing BPPV involves sequentially turning the head in a way that helps remove the crystals and help them float out of the semicircular canal. Several repositioning maneuvers performed in the same visit may be necessary.

Surgery is seldom necessary to treat this condition. In rare cases, the doctor may recommend a surgical procedure to block the posterior semicircular canal to prevent stones from entering and moving within the canal. While the surgical plugging procedure cures the problem, it carries some risk, including hearing loss.”
