About Acoustic Neuroma

What is an Acoustic Neuroma?

An acoustic neuroma (or schwannoma) is a benign tumor which manifests itself on the sheath surrounding the eighth cranial nerve, affecting the functions of the inner ear. Because many of the symptoms are also indicative of other less serious ailments, acoustic neuromas are often misdiagnosed or undetected.

If untreated, an acoustic neuroma is life-threatening, making it imperative that individuals with persistent inner-ear problems be evaluated to eliminate the possibility of an acoustic neuroma.

Diagnosis

Three non-invasive tests for diagnosis are:

  • BAER Test (Brainstem Auditory Evoked Response Test)
  • CAT Scan (Computerized Axial Tomography)
  • MRI (Magnetic Resonance Imaging)

Treatment Options (Information and Choices)

There are three treatment options available to a patient. These options are

  1. Observation (monitoring)
  2. Microsurgical removal (partial or total)
  3. Stereotactic Radiosurgery (single fraction) or Radiotherapy (multiple fractions)

Some important details that will result in treatment choice are:

  • your age
  • size of your tumor
  • symptoms that you have
  • your medical health

At this point you will probably be dealing with a medical specialist familiar with Acoustic Neuromas and the various treatment options. This is very important. He or she will offer you the best treatment option for your situation, taking all factors into account.

Surgery is the only option available for actually removing an Acoustic Neuroma. While a non-invasive treatment (like the gamma knife) sounds appealing, it is not a treatment of choice for everyone. Your medical specialist will help you with your decision, based on his/her medical training and experience.
