WebJun 18, 2024 · BPPV happens when calcium carbonate crystals, called otoconia, move and get trapped within organs of the inner ear that control balance. When the head changes position, the crystals roll around and push on tiny hairs that give the brain information about balance, causing paroxysmal positional vertigo. WebOtoconia. Otoconia are crystals of calcium carbonate and make the otolithic membrane heavier than the structures and fluids surrounding it. The otoconia are composite crystallites that overlie the macular sensory epithelium of the gravity receptors of most vertebrates and are required for optimal stimulus input of linear ...

Webcrystals precipitated around a nucleus that continuously grow forming concentric layers of organic matrix alter-nating with mineralized layers [12–14]. Nevertheless, both otoconia and otoliths can occur simultaneously in aquatic vertebrates [11]. Of these, only the otoliths of teleosts have been used in a wide range of scientific research ... WebPositional testing is critical to identify whether otoconia have been displaced into the SCC, causing a condition referred to as benign paroxysmal positional vertigo (BPPV). The addition of the otoconia into the endolymph renders the SCC sensitive to gravity. The Dix–Hallpike test is the most common positional test used to examine for BPPV (Dix and Hallpike, 1952).

WebBPPV occurs when tiny calcium crystals called otoconia come loose from their normal location on the utricle, a sensory organ in the inner ear. If the crystals become detached, they can flow freely in the fluid-filled spaces of the inner ear, including the semicircular canals (SCC) that sense the rotation of the head. Webto as the otolithic organs because they contain bio-crystals called otoconia (otolith in fish). These crystals are partially embedded in a honeycomb layer atop a fibrous meshwork, which are the otoconial complex altogether. This complex rests on the stereociliary bundles of hair cells in the utricular and saccular sensory epithe lium (aka macula).

WebMar 9, 2024 · The otoconia are made of calcium carbonate (CaCo3) combined with a protein matrix protein (about 40% of the volume). Calcium carbonate is also a constituent of "limestone", so otoconia are essentially a mixture of stone and a protein - -something like concrete with straw mixed in. They have a hexagonal symmetry.
