Vertigo is a common clinical disease. There are many kinds of vertigo diseases. Some patients are caused by nervous system diseases, and some patients are caused by middle ear and inner ear diseases. Therefore, they need to go to the Department of Neurology of Otolaryngology after the onset. Head MRI, audiology test, otoendoscope, vestibular function test and balance test can be done. Through these auxiliary tests, combined with the doctor's clinical experience, it is helpful to judge the condition. If the vertigo is caused by earwax, manual repositioning treatment can be done. If it is dizziness caused by sudden deafness, it can be considered to use drugs to improve circulation by nourishing nerves. Some patients can also be treated with hyperbaric oxygen.
