Otolithiasis is a peripheral vestibular disorder characterized by recurrent episodes of transient vertigo and characteristic nystagmus induced by changes in head position, and is often self-limiting. 1. The pathogenesis of otolithiasis is mainly due to the dislodgement of otoliths from the semicircular canals, and due to the change of body position, the otoliths keep swimming in the semicircular canals, which stimulate the vestibular receptors, and thus vertigo symptoms appear. 2. Patients with otolithiasis may have sudden attacks when their head position changes, with symptoms of rotational vertigo and dizziness accompanied by nausea, vomiting, nystagmus, and are prone to recurrent attacks, which often last for about a minute and are relieved automatically, but with varying lengths of intervals. 3. Otolithiasis is mainly treated by manipulation and repositioning, and can be treated with medication when vertigo attacks occur. It is recommended to go to the hospital in time and cooperate with the doctor to treat the symptoms.
