can occur anywhere along the vestibular nerve but are most likely to occur where the vestibulocochlear nerve passes through the tiny bony canal that connects the brain and the inner ear.

How do bilateral acoustic neuromas usually occur?
occur as part of a hereditary condition called Neurofibromatosis Type 2 (NF2). A person with NF2 has inherited a predisposition for developing acoustic neuromas and other tumors of the nerve cells
What have recent studies pointed to as increasing the risk of developing acoustic neuromas?
Recent studies in Europe have suggested a possible connection between the widespread use of mobile phones and an increased risk of developing acoustic neuromas
Can dizziness be prevented?
Some cases of dizziness cannot be prevented. Acoustic neuromas, for example, are not predictable or preventable.
What are the symptoms of acoustic neuroma?
most common first symptom of an acoustic neuroma is hearing loss, which is often accompanied by a ringing sound (tinnitis). People with acoustic neuromas sometimes report difficulties in using the phone
When is an MRI used to diagnose an acoustic neuroma?
If an acoustic neuroma is strongly suspected then magnetic resonance imaging (MRI) is usually performed. The MRI is a very accurate evaluation that is able to detect nearly 100% of acoustic neuromas
What symptoms can larger acoustic neuromas cause?
more likely to cause dysequilibrium. Dysequilibrium, which is characterized by minor clumsiness and a general feeling of instability, occurs in nearly 50% of people with an acoustic neuroma
What is Neurofibromatosis type 2?
hereditary condition associated with an increased risk of bilateral acoustic neuromas, other nerve cell tumors and cataracts.
What does acoustic neuroma mean?
Acoustic Neuroma is a brain disease in which certain parts of the brain degrade resulting in deafness. There are currently no treatments for this disease other than surgery.
What is the NF2 gene responsible for?
The NF2 gene is responsible for helping to prevent the formation of tumors in the nerve cells. In particular the NF2 gene helps to prevent acoustic neuromas
When will a person with NF2 develop an acoustic neuroma?
The mean age of onset of acoustic neuroma in NF2 is 31 years of age versus 50 years of age for sporadic acoustic neuromas.
What treatments are available for patients with acoustic neuromas?
surgery, radiation, and observation. The physician and patient should discuss the pros and cons of the different options prior to making a decision about treatment
What causes neural hearing loss?
Permanent neural hearing loss most often results from damage to the acoustic nerve and the parts of the brain that control hearing. Strokes, multiple sclerosis , and acoustic neuromas are all possible causes of neural hearing loss.
