The loss of hearing excludes the individual from many important external stimuli, and adjustment to this deprivation imposes profound challenge. Vestibular function ensures one’s ability to stand steadily, stabilize eye position during head movement, and move about gracefully. Hence, an understanding of the functions of the eighth cranial nerves and their derangements by disease is as much the concern of the neurologist as the otologist. Generally, the association of vertigo and deafness signifies a disease of the end organs for hearing and vestibular function, or of the eighth nerve. The precise locus of the disease is determined by tests of labyrinthine and auditory function, described further on, and by findings on neurologic examination and imaging studies that implicate the primary and secondary connections of the eighth cranial nerve.
