Benign paroxysmal positional vertigo, also known as otoliths, is a relatively strong vertigo and nausea that occurs a few seconds after a head movement or body posture change and lasts for tens of seconds, usually lasting no more than one minute. The duration of the disease varies, mostly for a few weeks, but individually for months or years. Causes: In the ear, there are three organs that manage the balance, including the three semicircular canals, the ellipsoidal bursa and the balloon, whose function is to feel the body’s own posture and movement state as well as the head in space, and play an important role in maintaining the body’s balance. The ellipsoidal bursa contains ellipsoidal bursal spots with calcium carbonate crystals (otoliths) attached to them, which act as sensory stimulators. If this calcium carbonate is dislodged and accidentally falls into the semicircular canal, it can cause otolithiasis. Traumatic brain injury, lack of blood supply to the brain, and high blood pressure can cause the dislodgement of otoliths. Diagnosis: A position test by an otolaryngologist at a hospital can confirm the diagnosis. Treatment: It is usually cured by applying a manual repositioning, which depends on the hallux valgus where the lesion is located. We have developed our own method of otolithology based on the principles of treatment, which has been published in foreign professional journals.
