Have you or someone close to you ever had the situation where you get up in the morning and suddenly the sky spins around and you feel like you’re going to tumble out of bed, so you have to fall down, feel the dizziness go away instantly, so you get up again, fall down again, followed by nausea and maybe vomiting? In this case, you probably have otoliths. ”Otolithiasis, also known as benign paroxysmal positional vertigo, is one of the most common forms of otogenic vertigo. It is short-lived, can recur and has a good prognosis. The otoliths are normally attached to the otolithic membrane, but when some pathogenic factors cause the otoliths to detach, the detached otoliths will swim in the fluid called endolymph in the inner ear, and when the body’s head position changes, the position of these semicircular canals also changes, and the submerged otoliths will move with the flow of the fluid, thus stimulating the semicircular canal hair cells and causing vertigo. The duration of otolithic vertigo is usually short, often less than a minute, and is closely related to the head position. Typical otolithic vertigo occurs in a fixed lateral head position in a certain direction, or the position is significantly more severe than other positions of vertigo. It often occurs with changes in head position such as getting up, turning over, raising the head, or lowering the head. Patients often feel a sense of spinning or tipping, often accompanied by nausea and vomiting. The diagnosis of otolithiasis is relatively simple. The doctor can confirm the diagnosis by a history of recurrent transient vertigo and a simple postural test (Dix-hallpic test), and treat the patient accordingly. This includes various repositioning treatments, habituation treatments, etc. Some patients have heavy symptomatic manifestations and high psychological burden. In fact, if the disease is fully understood and recognized, and the panic is eliminated, the symptoms can also subside.
