MRI is a valuable imaging diagnostic method in the clinical examination of diseases related to the inner ear and cranial nerves, especially the vestibule, cochlea and semicircular canals can be easily examined.

MRI of the inner ear helps to assess whether the structure of the cochlea is normal or not, and whether the cochlear nerve is present or not. In many cases where the cochlear nerve is aplastic or hypoplastic, causing deafness in young children, electrode placement will be difficult and the prognosis for hearing recovery is poor.

Sudden hearing loss can occur suddenly or over a period of hours. It is still unclear exactly what causes sudden hearing loss and medical experts around the world are working to better understand the phenomenon. The effects of sudden hearing loss range from mild to severe depending on other health factors and can potentially become permanent. Sudden hearing loss can also occur with tinnitus.
