Among the vertigo disorders identified so far, otoliths is one of the most common, mostly in middle-aged and elderly people, with a female predominance. Most of the causes are due to inner ear ischemia, middle ear infection or trauma.
1. Inner ear ischemia. The inner ear is in the deepest part of the ear and often forms otolith crystals. When the body does not supply enough blood to the inner ear, the inner ear ischemia will cause the otoliths to fall off and free in the endolymph, and once they come in contact with the hair cells of the semicircular canal to produce stimulation, it will affect the body’s balance, thus leading to otoliths.
2. Middle ear infection. The middle ear is a relatively fragile area of the human ear and is particularly susceptible to infection and inflammation, especially in the mastoid part of the middle ear.
3. Trauma. Trauma mainly refers to head trauma, such as mild head injury, which can have a certain impact on the ear and then prompt the otoliths to fall out. It is worth noting that it is not only trauma, but if the head suddenly accelerates, it may also have an effect on the ear.
These are the main factors that trigger otoliths, so be sure to pay attention to your own health protection, and in the event of a condition, go to a nearby hospital for timely examination and consultation.
