Benign paroxysmal positional vertigo, or “otolithosis”, is a vertigo disorder that originates in the inner ear and belongs to the category of peripheral vertigo. The pathogenesis of vertigo is that the otoliths attached to the otolithic membrane are dislodged by certain pathogenic factors, and these dislodged otoliths flow in the endolymphatic fluid of the inner ear and therefore enter the semicircular canals, which are normally free of otoliths. 1 minute. These symptoms are position-dependent and therefore paroxysmal in nature. The clinical manifestations are: transient vertigo of less than 1 minute duration with nystagmus (horizontal or rotational) when the patient is in a specific position such as sitting up, lying down, raising or lowering the head, turning the head, or turning over. The treatment of benign paroxysmal positional vertigo includes medication and surgery. If the vertigo symptoms are mild and tolerable, patients can choose conservative medication (the specific medication is subject to the doctor’s consultation) and pay attention to avoiding the position that causes vertigo attacks. Patients with more severe symptoms need to be treated surgically (posterior potbelly neurectomy or hemianoplasty).
