Treating the canalith jam form of BPPV

Blockages in the canal that keep particles from exiting with maneuvers are very rare, fewer than 1 in 100 cases of BPPV.  We don’t yet know exactly how rare it is.  However, these rare cases can still be  treated with maneuvers.  Some modifications are needed to get the particles past the blockage.

Canalith jam: a rare cause of BPPV

Rarely, maneuvers don’t seem to work, even though the vertigo seems to be BPPV.  The affected person is able to make spells happen by making head movements like lying down, rolling over or tipping the head up, but the particles seem to be stuck, unable to exit the ear.   Each time a maneuver is done,…

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 one…

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. They…

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 being…

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 brain…

The inner ear can be malformed

The inner ear is a delicate and complex structure, so it is critical that it be formed properly.  Abnormalities in development arising prior to birth, called congenital malformations, can be associated with a complete absence of vestibular function from birth.  Milder malformations can at first be silent, only to cause progressive or sudden losses of…

Chiari malformations

Chiari malformations are distortions at the base of the brain that may be present at birth or can form throughout life.  The cerebellum, the part of the brain that controls balance and coordination, sits just above the opening at the bottom the skull (the foramen magnum) through which the brainstem passes to the spinal cord. …

What if exercise worsens your vertigo?

It’s a mantra everywhere: exercise is good for you.  If you want to lose weight, you should diet and exercise.  If you want to slow aging, exercise is key.  But what do you do if exercise sets off vertigo?  Is the dizziness a sign you are hurting yourself even more?  Should you avoid exercise?  That…

The truth about exercise

At the New Year we’re always looking for good resolutions.  How about a book that helps you and your family?  An exciting new book is out about exercise, by the noted vertigo expert and famed neurologist, Dr. Robert Baloh.  He has researched vertigo for over 50 years and saw thousands of patients in his practice…
