Overview
Symptoms of acoustic neuroma may vary depending on the cranial nerve involvement, cerebellar compression, mass size and tumor progression. hearing loss and tinnitus almost always are seen in cochlear nerve involvement, while unsteadiness is common among patients with involvement of the vestibular nerve. Trigeminal nerve involvement occurs among one-sixth of patients and usually presents with facial paresthesia or hypesthesia. Facial paresis, taste disturbances, xerophthalmia, paroxysmal lacrimation, and xerostomia are less common symptoms which may present due to involvement of the facial nerve.
History and Symptoms
Symptoms and signs of Acoustic neuroma considerably dependent on the size of tumor, for instance, generalized headache occurs in less than 20% of patients with small acoustic tumors (less than 2cm), although it can occur in 43 to 75% of patients with tumor over 4cm in diameter.[1][2][3] In table 1 and table 2 there are information about the frequency of major symptoms and signs and cranial nerve disturbances respectively.[4] [5]

Cranial nerve
Cranial nerve disturbances was related to the Cochlear nerve and Trigeminal nerve. The Facial nerve disturbances occurs in more sever cases.
