vestibulocochlear nerve the eighth cranial nerve, which emerges from the brain between the pons and medulla oblongata, behind the facial nerve. The vestibular division serves the vestibule of the ear and the semicircular canals, carrying impulses for the sense of equilibrium. The cochlear division serves the cochlea and carries impulses for the sense of hearing. Called also acoustic nerve and auditory nerve. See Appendix 2-6.

Our study illustrates that imaging studies in patients with congenitally sensorineural hearing loss should not focus just on the vestibulocochlear nerves [19] or on cochlea [20, 21].
Radiology gives information regarding the type of malformation, additional pathologies in the middle ear and mastoid, and the presence or absence of the vestibulocochlear nerve. There has been a debate about which of the two modalities, HRCT or MRI, should be used in the preoperative evaluation of candidates undergoing cochlear implantation.
A present facial nerve and vestibulocochlear nerve branching into the cochlear, inferior, and superior vestibular nerve were identified as normal.
Maximum malformations found in a single ear were 7 structural malformations which included malformation of cochlea, modiolus, vestibule, vestibular aqueduct, semicircular canals, internal auditory canal, and vestibulocochlear nerve. Five out of 78 (6.4%) malformed inner ears showed all 7 structural malformations, 6 ears (7.6%) had 6 malformations, 7 ears (8.9%) had 5 malformations, 15 ears (19.2%) showed 4 malformations, 19 ears (24.3%) had 3 malformations, 23 ears (29.4%) had 2 malformations, and only 3 ears (3.8%) had single isolated malformation.
Anomaly of the vestibulocochlear nerve occurred along with a malformed labyrinth.
