otoconia การใช้

• On top of this layer lie calcium carbonate crystals called statoconia or otoconia.
• When the head is still, gravity causes the otoconia to clump and settle.
• The otoconia floats freely in the inner ear fluid, causing disorientation and vertigo.
• In mice lacking the otoconia of the utricle and saccule, this retained acoustic sensitivity is lost.
• The Epley maneuver does not address the actual presence of the particles ( otoconia ); rather it changes their location.
• These rats suffered from a balance defect due to a leak of otoconia in the inner ear, like nmf333 mice.
• The hair cells of the otolithic organs are blanketed with a jelly-like layer studded with tiny calcium stones called otoconia.
• Statoconia ( also called otoconia ) are numerous grains, often spherical in shape, between 1 and 50 祄; collectively.
• BPPV is the most common cause of vertigo, a problem attributed to a detached otoconia in one of the semicircular canals.
• Treatment for the disorder includes antihistamines and anticholinergics, and the disorder often goes away without surgical removal of the free otoconia.
• Benign paroxysmal positional vertigo, or BPPV, is a disorder caused by the breaking off of a piece of otoconia from the otoliths.
• When the head moves, the otoconia shift, which stimulates the cupula to send false signals to the brain, producing vertigo and triggering nystagmus.
• When the patient is passively positioned from an upright seated posture down to a lying ( supine ) position, this momentum helps to dislodge the otoconia ( crystal ) embedded in the cupula.
• Benign paroxysmal positional vertigo ( BPPV ) is the most common vestibular system disorder and occurs as a result of otoconia detaching from the otolithic membrane in the utricle and collecting in one of the semicircular canals.
• Following the treatment, the clinician may provide the patient with a soft collar, often worn for the remainder of the day, as a cue to avoid any head positions that may once again displace the otoconia.
• The mechanical coupling of the otoconia to the hair cell sensory sterocilia at the surface of the vestibular sensory epithelium is mediated by two of the extracellular matrix, each on with a specific role in the mechanical filaments secures the membrane above the surface of the epithelium.
• Embedded in this membrane are calcium carbonate crystals, called otoconia, or " ear rocks . " As the head is tilted forward or backward, the otoconia move the hair cells in a similar fashion to the semicircular canal fluid movement and cause depolarization of the hair cells.

• The device is filled with fluid and a particle representing the otoconia ( loose hard particles ) associated with BPPV . The device works like a visual set of instructions and guides the user through the treatment maneuver for BPPV . This maneuver is called the particle repositioning maneuver or Epley maneuver.
• Such binding of OPN to various types of calcium-based biominerals  such as calcium-phosphate mineral in bones and teeth, calcium-carbonate mineral in inner ear otoconia and avian eggshells, and calcium-oxalate mineral in kidney stones  acts as a mineralization inhibitor to regulate crystal growth.
