Postural vertigo, also known as benign positional vertigo, is also known as otolithiasis. Patients usually present with sudden dizziness when the head position changes, which can be accompanied by seeing things rotating, and in severe cases, nausea and vomiting may also occur. In repeated attacks, deafness and tinnitus can occur. In most patients, the duration of symptoms is relatively short, ranging from a few seconds to 1-2 minutes, and can be relieved suddenly or repeatedly, mainly by symptomatic treatment. If the symptoms of dizziness are severe, symptomatic anti-dizziness treatment can be administered. Commonly used medications include betahistine hydrochloride, flunarizine hydrochloride capsules, and difenidol hydrochloride, etc. The disease is a form of peripheral vertigo, which is caused by the detachment of the otolith from the semicircular canal.
