Detailed explanation-1: -CN VIII pathology can result from direct trauma, congenital malformations, tumor formation, infection, and vascular injury. Presenting symptoms include vertigo, nystagmus, tinnitus, and sensorineural hearing loss. Also, the involvement of the facial nerve due to its proximity should not be excluded during evaluation.

Detailed explanation-2: -The vestibulocochlear nerve emerges laterally at the cerebellopontine angle, which is the junction between the pons, medulla and cerebellum. Once it emerges from the cerebellopontine angle, it enters the internal acoustic meatus where it separates into its two branches: the cochlear nerve and the vestibular nerve.
