Otoliths are generally not particularly serious, but are a common inner ear disease with a relatively high overall incidence, which can easily lead to related clinical symptoms. The more common symptoms are sudden onset of vertigo, which lasts for a short time and is associated with a change in body position, and may also be accompanied by visual rotation, nausea and vomiting. Although otoliths can easily cause vertigo and affect the quality of life, it is generally not a direct threat to the life safety of patients, and some patients can recover on their own because their condition is mild. If it is a simple otolith, it can generally be treated by manual repositioning. Before the repositioning treatment, a balance test should be done to clarify the specific lesion of the semicircular canal, and after the clarification, targeted manual repositioning treatment can be carried out, and most patients have better treatment results. For some patients with particularly serious disease, if the effect of simple manual repositioning is not good, they can be treated with machine chair repositioning and oral anti-vertigo medication, betahistine mesylate tablets are more commonly used.
