H-BPPV and Entrapped Particles

Sometimes maneuvers for H-BPPV don’t seem to work, and this is especially true for the apogeotropic type, when the eyes seem to beat toward the ceiling when lying on your side.  It’s very rare to have this happen.  Most of the time, lying flat on your back until the dizziness stops and then doing oneContinue reading “H-BPPV and Entrapped Particles”

Why is HBPPV such a problem?

Here’s a photograph of the cupula of a mouse, taken by Dr. Olivia Kalmanson at the University of Colorado. The cupula looks dark green because it’s transparent, so the background can be seen right through it. To make it easier to see, we’ve piled otoconia, the gravity sensor’s crystals, on the middle of it. TheyContinue reading “Why is HBPPV such a problem?”

Cupulolithiasis in BPPV:  Rare, or non-existent?

Newsflash: Read our science article, Cupulolithiasis: A Critical Reappraisal, at http://doi.org/10.1002/oto2.38 BPPV is the best understood form of vertigo, and usually goes away promptly with simple maneuvers.  Sometimes, though, it can persist, and in those cases, a somewhat different and rare form is diagnosed, called cupulolithiasis.  This means “stones on the cupula”, the cupula beingContinue reading “Cupulolithiasis in BPPV:  Rare, or non-existent?”
