It occurs as a loss of hearing or deafness which is ispilateral in nature. The balance is disturbed and there is an alteration in the gait. There occurs nausea and vomiting which is associated with the vertigo. There is a pressure in the ear which is mainly due to the disturbance in normal vestibule cochlear nerve function.
Nearly, four out of five patients report tinnitus which is a unilateral high pitched sound which resembles a steam kettle. There are large tumors which can compress the brain stem and may involve the local cranial nerves. The nearby facial nerve can be involved and this may lead to the ispilateral facial weakness. It is the 7th cranial nerve. It also affects the senses, glandular secretions and taste sensations as it involves the anterior two third of the tongue.
The trigeminal nerve is also involved in which there occurs a loss of sensation in the affected side of face and mouth. It is the 5th cranial nerve. There are glosso pharyngeal and vagus nerves which are not commonly involved and they may lead to altered gagging and swallowing reflexes.
The large tumors increase the intra cranial pressure and lead to the headache, vomiting, and change in the conscious levels.
