Benign paroxysmal positional vertigo (BPPV), commonly known as otolaryngitis, accounts for 17-52.5% of all vertigo-inducing disorders and is more common in women, with recurrent episodes of transient vertigo associated with changes in head position and characteristic nystagmus. It may be accompanied by cold sweat, panic, nausea, vomiting and other adverse experiences. Patients often sleep and walk in a fixed head position in order to prevent vertigo attacks, and over time they become anxious and depressed, and their neck muscles become tense and painful. According to the statistics, the treatment effect is good, 90% of the patients can be cured by repositioning.
