When both divisions of the vestibulocochlear nerve are affected by disease, symptoms may include ringing in the ear , a sensation of spinning , and other symptoms such as deafness. These nerves are twined together to form the vestibulocochlear nerve (eighth cranial nerve). The ear is the organ of hearing and balance. A lower motor neuron lesion, or peripheral facial palsy refers to any injury that affects the facial nerve from the facial nucleus up until it gives off its terminal branches. It is an intracranial nerve which runs from the sensory receptors in the internal ear to the brain stem nuclei and finally to the auditory areas: the post-central gyrus and superior temporal auditory cortex. Problems with the vestibulocochlear nerve can result in vertigo, vomiting, ringing in the ears, a false sense of motion, motion sickness, or even hearing loss. The sensory nerve endings (hair cells) of the vestibulocochlear cochlear nerve can get damaged by ear infections.
