Detailed explanation-1: -An acoustic neuroma (also known as a vestibular schwannoma) is a benign tumor that originates on the eighth cranial nerve, which connects the inner ear with the brain. This nerve, called the vestibulocochlear nerve, is involved in transmitting sound and sending balance information from the inner ear to the brain.

Detailed explanation-2: -Most acoustic neuromas occur on the vestibular portion of the eighth cranial nerve. Because these tumors are made up of Schwann cells and usually occur on the vestibular portion of the eighth cranial nerve, many physicians prefer the use of the term vestibular schwannoma.

Detailed explanation-3: -The signs and symptoms of acoustic neuroma are attributed to the involvement of the cranial nerve VIII, compressing surrounding cranial nerves, cerebellum, brainstem, as well as raised intracranial pressure (ICP).
