The symptoms of BPPV include dizziness or vertigo, lightheadedness, imbalance, and nausea. In a recent study, 9% of a group of urban dwelling elders were found to have undiagnosed BPPV (Oghalai et al., 2000). About 50% of all dizziness in older people is due to BPPV. While BPPV can occur in children (Uneri and Turkdogan, 2003), the older you are, the more likely it is that your dizziness is due to BPPV. About 20% of all dizziness is due to BPPV. They are probably dissolved naturally as well as actively reabsorbed by the "dark cells" of the labyrinth (Lim, 1973, 1984), which are found adjacent to the utricle and the crista, although this idea is not accepted by all (see Zucca, 1998, and Buckingham, 1999).īPPV is a common cause of dizziness. Normally otoconia appear to have a slow turnover. The utricle may have been damaged by head injury, infection, or other disorder of the inner ear, or may have degenerated because of advanced age. ![]() While the saccule also contains otoconia, they are not able to migrate into the canal system. Ear rocks are small crystals of calcium carbonate derived from a structure in the ear called the "utricle" (figure1 ). This debris can be thought of as "ear rocks", although the formal name is "otoconia". In Benign Paroxysmal Positional Vertigo (BPPV) dizziness is generally thought to be due to debris which has collected within a part of the inner ear. ![]()
