You may not be able to see the otoliths falling off?
New imaging study brings clues to vertigo diagnosis

If you feel dizzy as soon as you lie down or turn over, be careful because it may be "benign paroxysmal postural vertigo", which is also commonly known as otolith loss. This type of vertigo is mostly related to the dissociation of tiny otoliths in the semicircular canals of the inner ear, which can stimulate the balance system and cause brief but repeated dizziness and nystagmus. Yuan Jing's research team found that high-resolution special computed tomography has the opportunity to see scattering images similar to "snowflake spots". It is speculated that it is related to the "Tyndall effect" caused by otoliths suspended in the semicircular canals, and may become an important tool for diagnosing otolithiasis in the future.
