Acoustic Neuroma

Acoustic neuroma is a benign tumor of the auditory nerves, related to hearing, near the ear. The tumor is considered to be a type of brain tumor. Although benign rather than malignant, it may nevertheless cause serious concern by pressing on the auditory nerves (causing hearing symptoms such as hearing loss ...

Introduction: Acoustic Neuroma

What is a vestibular schwannoma (acoustic neuroma)? A vestibular schwannoma (also known as acoustic neuroma, acoustic neurinoma, or acoustic neurilemoma) is a benign, usually slow-growing tumor that develops from the balance and hearing nerves supplying the inner ear. The ...1

Complications of Acoustic Neuroma

The tumor can also eventually cause numbness or paralysis of the face. If it grows large enough, it can press against the brain, becoming life-threatening. ...Source: MedLinePlus (NIH)3 ...

Causes of Acoustic Neuroma

A vestibular schwannoma is a benign, usually slow-growing tumor that develops from the balance and hearing nerves supplying the inner ear. The tumor comes from an overproduction of Schwann cells—the cells that normally wrap around nerve fibers like ...4

Types of Acoustic Neuroma

What is the difference between unilateral and bilateral vestibular schwannomas? Unilateral vestibular schwannomas affect only one ear. They account for approximately 8 percent of all tumors inside the skull; approximately one out of every 100,000 individuals per year develops ...6

Diagnosis of Acoustic Neuroma

How is a vestibular schwannoma diagnosed? Unilateral/asymmetric hearing loss and/or tinnitus and loss of balance/dizziness are early signs of a vestibular schwannoma. Unfortunately, early detection of the tumor is sometimes difficult because the symptoms may be subtle ...7

Genetics of Acoustic Neuroma

Bilateral vestibular schwannomas affect both hearing nerves and are usually associated with a genetic disorder called neurofibromatosis type 2 (NF2). Half of affected individuals have inherited the disorder from an affected parent and half seem to have a mutation for ...8

Treatments: Acoustic Neuroma

How is a vestibular schwannoma treated? Early diagnosis of a vestibular schwannoma is key to preventing its serious consequences. There are three options for managing a vestibular schwannoma: (1) surgical removal, (2) radiation, and (3) observation. Sometimes, the tumor is ...9
