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?”
A common malformation: Enlarged vestibular aqueduct syndrome (EVAS)
Since the inner ear is a pressure sensor, it is important to keep the pressures steady in the ear. This is a challenge because the ear bridges the space in the skull between the outside-the ear canal—and the inside, housing the brain. When you sneeze or strain, the pressure in the fluid around the brainContinue reading “A common malformation: Enlarged vestibular aqueduct syndrome (EVAS)”
