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 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..[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.
History
- Chronic gradual unilateral hearing loss is the most common symptom presents in 95 percent of patients. Tinnitus is associated symptom among patients with the involvement of cochlear nerve.
- True spinning vertigo is very uncommon presenting symptoms among patients with acoustic neuroma. Approximately 50% of patients with acoustic neuroma report disequilibrium and sense of unsteadiness while walking.
Common Symptoms
Less Common Symptoms
Cranial nerve
Cranial nerve disturbances was related to the Cochlear nerve and Trigeminal nerve. The Facial nerve disturbances occurs in more sever cases.

| VI | Abduction disorder | rarely seen |
