When there is sudden deafness with vertigo, the first consideration is vestibular organs, such as vagus or vestibular cochlear neuropathy, but it is important to exclude other diseases that cause vertigo. There is no anemia, hypoglycemia, endocrine disorders, and intracranial lesions, auditory neuroma, which can present these symptoms. In conclusion, patients with sudden deafness followed by vertigo should undergo some necessary tests, such as audiometry, nystagmography with hot and cold water test, and brain MRI, to rule out other diseases of vertigo. Based on the tests, we can determine where exactly there is a lesion that is causing the vertigo and deafness. Therefore, if you have this condition, it is important to go to the doctor and have some necessary tests done in time to clarify the diagnosis as soon as possible.
