Objective: To investigate the causes of misdiagnosis of benign positional vertigo Methods: 35 cases of benign positional vertigo misdiagnosed in outside hospitals were analyzed, among which 15 cases were misdiagnosed as Ménière’s disease, 6 cases were misdiagnosed as insufficient blood supply to the basilar artery, 4 cases were misdiagnosed as vestibular neuronitis, 3 cases were misdiagnosed as sudden deafness with vertigo, 5 cases were misdiagnosed as cervical spondylosis, and 2 cases were misdiagnosed as unknown. Results: 25 cases of hallux valgus were diagnosed by Dix-Hallpike test and roll test under video nystagmography, including 20 cases of posterior hallux valgus, 3 cases of horizontal hallux valgus, 2 cases of posterior hallux valgus combined with horizontal hallux valgus, and 10 cases of jugular crista parietal stone. The main characteristic of benign positional vertigo is vertigo with nystagmus when the head changes to a certain position, with an incubation period of 1 to 5 s and a duration of less than 1 minute, and the symptoms can recur. The symptoms can be recurrent. The Dix-Hallpike test and roll test under video nystagmography are the gold standard for the diagnosis of benign positional vertigo. It can improve the positive rate of nystagmus. 3.Many patients with true vertigo can also have increased vertigo when their head position changes in the acute stage, which can be easily confused with benign positional vertigo. 4.Some patients have self-limiting effect, and the symptoms can be reduced or even disappeared after misdiagnosis and mistreatment.
