In vestibular nerve section for
Ménière's disease, the nerve that controls hearing and
balance on the affected side is identified. Then the balance portion of that
nerve is cut, leaving the part of the nerve that controls hearing intact. The part of the nerve that controls hearing is close to the part that controls
balance, so there is a risk of hearing loss in the affected ear.
During the recovery period, the brain adapts to the lack of input
from the ear that was operated on, and normal balance sense usually
returns. Other symptoms of Ménière's disease, such as tinnitus, hearing loss, and fullness in the ear, are not helped by this surgery. You may need to stay on a low-sodium diet and take diuretics.
