Where are the ear crystals?
Each inner ear, or vestibular system, has three semi-circular canals – the posterior, the anterior and the horizontal canal. Ear crystals live on a membrane in a nearby vestibular sensory organ called the utricle. All of the semi-circular canals share fluid with the utricle, so the ear crystals can float into the semi-circular canals if they break off the membrane.
The runaway ear crystals cause BPPV (Benign Paroxysmal Positional Vertigo).
There is a shared entry point of the posterior and anterior canal connecting to the utricule where the ear crystals normally live is called the “common crus.” The horizontal canal connects with the utricle also.
In a case of BPPV, a person can have a misplaced crystal(s) floating in any of one or combination of their 6 inner ear canals. Those crystals are supposed to be in the utricle organ in the inner ear, but when a person has BPPV, the crystals have moved and gone floating in one of the semi-circular canals.
This can happen through hormone changes, head trauma or normal aging (amongst other causes).
Most people likely have more than one crystal floating loose, possibly even a sediment of thousands of ear crystals.
Sometimes people even have BPPV in both ears. Anyone with a head injury is most likely going to have it in both ears because each ear probably had ear crystals break loose from the trauma and go floating away from where it belongs into a semi-circular canal.
Risks of Self-Treatment for Ear Crystals
The reason the self-Epley treatment does work for a lot for people is because the inner ear canals are not totally set horizontal in relation to gravity. The posterior canal is a little lower in the head than the others, making it the most common place the crystals end up. The Epley maneuver only treats the posterior canal.
If people don’t do the treatment right, or they have a sediment of ear crystals, then they can convert it to the horizontal or anterior canal.
If people have a lot of crystal sediment in their canal and they improperly treat themselves with the Epley maneuver, the crystals end up converting into the other canal because they don’t pass through the common crus.
Then the person ends up with ear crystals in two canals! A so-called “canal conversion.”
And that’s much more difficult to treat, but still possible in more treatment sessions.
I see this result in people that try to treat themselves and from clinicians that are not well trained in the maneuvers, those that are “dabbling.”
People with “multi-canal BPPV” and persistent BPPV are the patients I usually need to see more than once. They may need 2-3 visits with me, or more in order to completely resolve their complaints of ear crystals.
Due to the risk of not doing the treatment correctly, fear of falling during the maneuver, possibility of a panic attack, and the need for an assessment to determine if other canals are involved, I do not recommend for people to try to treat themselves for BPPV ear crystals.
In my practice, I see a lot of patients who have all types of BPPV and all combinations of canals with ear crystals, and I get excellent results with these patients.

hi Dr. Bell, I’m 52 and recently I had been doing alot of bending over after not being able to do much in the last year with depression.
I started out with some stretching and yoga, and recently started taking care of my garden. Alot of bending over!!
I woke one morning with really bad vertigo…my sister talked me into doing the bed roll which her doctor told her to go home and perform told her it would take 5 mins from start to finish.
So I tried it. I knew it was my right side by how I tried to get up out of bed on my right side it was terrifying And the bed roll it was horrendous to say the least..worked but something weird happened.
As I was at the end and up on my shoulder looking down to the floor I went to sat up slowly and turned looking straight forward i got super dizzy so bad I kinda had to throw myself back onto the bed.
Why would that happen at the end of the procedure? And when I would check to see if it’s the left side nothing really happened as far as dizziness. I’m really concerned.
Hi Shawmarie,
I am glad you are coming out of the depression and getting more active! Congratulations.
I have this blog on Dizziness with Gardening.
This blog is on Common Pitfalls of trying to treat yourself for vertigo.
I cover additional information in this blog too.
This blog is on the Reasons to seek Professional Vertigo Care.
I do not support people trying to treat themselves because unusual things can occur like what you experienced.
I suggest you find a Vestibular health care provider using this blog to search online.
Best wishes!
I had a root canal on # 2 and crown over it due to crack and just a crown on # 3. I felt really dizzy. I was in the chair for around 2 1/2 hours. I drove home which was a two hour or so drive and I’m still feeling like I’m going to fall over the next day. Is this normal and if it is how long dies this feeling last?
Hi Victoria,
I am sorry to hear about this!

Vertigo just returned a second time. The first time my chiropractor did the Epley move three times. After that, vertigo subsided. That was about 3 months ago. It just came back. My question to you is why do the crystals fall out of the ear. Can we stop the crystals from
Hi John,
I am so glad you have someone nearby who knows how to treat your vertigo. That is wonderful!
