Meniere’s syndrome presents with recurrent episodes of rotational vertigo, sensorineural hearing loss, tinnitus and a feeling of fullness in the ear. There is no vertigo between episodes. The Chinese Academy of Otolaryngology established the diagnosis of Meniere’s disease in October 1996 based on: 1. Recurrent episodes of rotational vertigo lasting from 20 minutes to several hours, with at least two episodes. It is often accompanied by nausea, vomiting and balance disturbance. No loss of consciousness. May be accompanied by horizontal or horizontal rotational nystagmus. 2. At least one pure tone audiometry for sensorineural hearing loss. Early low-frequency hearing loss, hearing fluctuations, with progressive hearing loss gradually aggravated. Resonance phenomenon may occur. 3.Tinnitus is intermittent or persistent, and it changes before and after the vertigo attack. 4. There may be a sense of ear swelling and fullness. 5.Exclude vertigo caused by other diseases, such as positional vertigo, vestibular neuritis, drug-induced vertigo, sudden deafness with vertigo, vertigo caused by insufficient blood supply to the basilar artery and intracranial occupational lesions. The diagnostic criteria for transient ischemic vertigo of the vertebral basilar artery (i.e., cervical vertigo) published by the NIH in 1990 are: 1. Motor disturbances, weakness of the left and/or right lower upper extremities and face, paresthesia or clumsiness in movement. 2. Sensory impairment, left, right or bilateral sensory deficit, numbness or abnormal sensation. 3.Loss of visual field on one or both sides, or blurred vision. 4.Balance disorder, vertigo, instability or ataxia, diplopia, dysphagia, or dysarthria. 5. Sudden onset of symptoms, usually lasting 2 to 15 minutes and resolving within 24 hours with residual nerve deficit. In addition, the attacks of cervical vertigo are related to neck movement and certain head position, and are still mostly accompanied by headache, with fewer cochlear symptoms than in Meniere’s disease. In summary, the simple distinction can be made by the length of the attack, whether it is related to the neck position, and the presence of ear symptoms, but the final diagnosis needs to be made by a doctor at the hospital.
