Acoustic Neuroma What is an Acoustic neuroma? Acoustic neuromas are usually benign tumors that grow along the balance nerves deep inside the skull. They usually occur somewhere between the inner ear and the brainstem and generally grow slowly over a period of years. What are the signs and symptoms? How can it harm me? Although sometimes there may be no symptoms at all, dizziness, imbalance, gradual or sudden one-sided hearing loss, ringing / tinnitus may all be indications of acoustic neuroma growth. Other symptoms may involve headaches, facial paralysis, vertigo, numbness of the eye and other nerve paralysis etc. Acoustic neuromas cause problems by their growth in a space limited by the size of the skull. The larger it gets, the less room your brain has to function. The worst case scenario occurs when the brainstem (responsible for vital life functions such as breathing and heart beat regulation) is crushed by growing tumor causing death. What is the natural course of this process? The average growth rate for most acoustic neuromas is relatively slow. However the patterns are very variable. Sometimes tumors that have remained quiet for many years suddenly awaken and expand. As they expand, the compression on the balance nerve, hearing nerve and facial nerve can occur. Usually, the compression is slow and the changes occur so gradually that the imbalance and hearing loss can go un-noticed. Many times a hearing test picks this asymmetrical hearing loss as the first manifestation of the disease. Since the facial nerve is the hardiest of the bundle (the balance nerve, hearing nerve and facial nerve all run together in a bone encased canal together) , it is usually the last of the bunch to become paralyzed. If compression is on the cerebellum, coordination functions can be affected. If compression is on the brainstem, vital functions can be affected.

Causes, Incidence, and Risk Factors These tumors are thought to arise when there is a defect in a certain tumor suppressor gene, which normally prevents tumors from occurring. The cause of the genetic defect is not known. However, acoustic neuroma is often linked with the genetic disorder neurofibromatosis type 2 Acoustic neuromas are relatively uncommon in general, but they are one of the most common types of brain tumors. They affect approximately 1 out of 100,000 people per year. The tumor is most commonly located at the base of the brain, where the auditory nerve leaves the skull cavity and enters the bony structure of the inner ear.

One scenario might be: you can't hear anything when you put the telephone to one of your ears. Your doctor now delivers the bad news that you have a brain tumor, AND the Good News that it is perfectly benign. You are bombarded by different therapy options (Gamma Knife, Surgery, etc.) including the idea to forget about the whole thing. Everyone and their brother and/or sister has a strong opinion; only you are left to make the decision. Welcome to the world of acoustic neuromas! This tumor (called a "schwannoma") arises from the myelin forming cells (Schwann cells") of the 8th cranial nerve at the point where the peripheral part of the nerve meets the brain part of the nerve (called "Hensen's node"). Hensen's node is usually located in the inner ear canal that leads to our hearing apparatus, called the "acoustic meatus." This nerve is actually three nerves in one, two "vestibular" nerves (upon which the tumor actually grows) and the hearing nerve. Immediately associated with these nerves is the 7th cranial nerve, the nerve that controls the muscles of the face, salivation, tearing, and taste. The tumor grows just next to the brain stem, and when enlarged may actually compress it. Larger tumors also may involve the swallowing nerves down below, as well as the 5th nerve above which controls sensation to the face and eye. In other words, this is a very tightly packed and difficult area for involvement. Patients may present any combination of symptoms related to malfunction of these nerves, depending on the size, the pressure and location of the tumor.

Radiation may be delivered in a single fraction or dose requiring the patient to wear a headframe ( stereotactic radiosurgery ) and supervised by a neurosurgeon and a radiation oncologist. Radiation also may be given in several physician-supervised treatments during which the patient's head is immobilized by a thermoplastic mask. Which option is best depends on the size of the tumor and the age and general health of the patient. Two important considerations in either treatment are preserving the facial nerve and saving hearing, whenever possible.

I was diagnosed with an Acoustic Neuroma and had surgery performed in '91. In my research to become knowledgeable about this condition, I have come across many articles that will rebut your statements in today's paper. Although an acoustic neuroma tumor is non-cancerous, and yes, no one will die of cancer from this type of tumor; it does grow, albeit slowly, and will invade the cranial cavity. It will encompass several nerves, finally press upon the brain stem, to create severe nerve problems and cause eventual death to the patient. No one should take an acoustic neuroma lightly. Could you please correct your misleading information regarding Acoustic Neuroma and its treatment in a future column? Please urge any patient to see an Otolaryngologist (ENT specialist) immediately. A: You're right I should have been much more adamant about the reader seeking help sooner. Jean J Palasz, the president of the Acoustic Neuroma Association of Wisconsin was also kind enough to take the time to write and urge more clarification about acoustic neuroma.

acoustic neuroma What is an acoustic neuroma? An acoustic neuroma (sometimes called a neurinoma or vestibular schwannoma) is a benign (non-cancerous) tissue growth that arises on the eighth cranial nerve. The eighth cranial nerve is three separate nerves, one part associated with transmitting hearing and the other two with sending balance information to the brain from the inner ear. These nerves are adjacent to each other as the pass through the bony canal leading from the inner ear to the brain. This bony canal, called the internal auditory canal, is about one centimeter (0.4 inches) long, and it is here that acoustic neuromas usually arise from the sheath surrounding the eighth cranial nerve. The seventh cranial nerve or facial nerve which controls facial movement also passes through this bony canal along with important blood vessels. Where is your acoustic nerve and what does it do? The acoustic nerve arises from a part of the brainstem called the pons (in a region referred to as the cerebellopontine angle). The acoustic nerve and the vestibular nerve are run together and are attached to one another. Together they are called the eighth cranial nerve. The seventh cranial nerve controls the facial musculature (hence its other namethe facial nerve) and runs near the eigth nerve for part of its course. The acoustic portion of the eighth nerve goes to the cochlea of the ear and transmits hearing while the vestibular portion goes to the semicircular canals which are responsible for detecting motion (acceleration more technically) and hence are involved in the sense of balance. Most acoustic neuromas actually arise from the vestibular portion of the eighth nerve rather than the acoustic portion, therefore the synonym vestibular schwannoma is preferred by most medical authors.

95. Acoustic Neuroma Is The Name Commonly Applied To A Benign Tumor Arising From The acoustic neuroma. A patient with an acoustic neuroma has two options the patientcan either wait and see what happens over time, or pursue treatment. http://www.neurosurgery.ucsd.edu/cnd/acoustic_neuroma.htm

Acoustic Neuroma Introduction Diagnosis Acoustic Neuromas are most frequently diagnosed by MRI scan in a patient with unilateral hearing loss. Important information to be determined from the MRI scan are distance the tumor extends laterally in the auditory canal, the extent to which the tumor expands in the cerebello-pontine angle, and whether or not the brain stem is contacted or distorted. Other important diagnostic tests are the audiogram and the recordable brain stem audio evoked responses (BAERs) because these will provide indicators of the possibility of saving hearing. Classification Based on the MRI scan, Acoustic Neuromas fall into three classifications: Entirely intracanalicular , which means the entire tumor is no bigger than a bean and is completely within the bony canal. Intracranial extension without brain stem distortion , which means the intracranial portion of the tumor is small, i.e. 1-2 cm. Intracranial extension with brain stem distortion , which means the intracranial portion of the tumor is bigger than 2 cm and pressing on the stem of the brain. Treatment Options A patient with an acoustic neuroma has two options: the patient can either wait and see what happens over time, or pursue treatment. When treatment is selected there are only two viable alternatives:

MAIN SEARCH INDEX Acoustic neuroma Definition Description Causes and symptoms Diagnosis ... Resources Definition An acoustic neuroma is a benign tumor involving cells of the myelin sheath that surrounds the vestibulocochlear nerve (eighth cranial nerve). Description The vestibulocochlear nerve extends from the inner ear to the brain and is made up of a vestibular branch, often called the vestibular nerve, and a cochlear branch, called the cochlear nerve. The vestibular and cochlear nerves lie next to one another. They also run along side other cranial nerves. People possess two of each type of vestibulocochlear nerve, one that extends from the left ear and one that extends from the right ear. The vestibular nerve transmits information concerning balance from the inner ear to the brain and the cochlear nerve transmits information about hearing. The vestibular nerve, like many nerves, is surrounded by a cover called a myelin sheath. A tumor, called a schwannoma, can sometimes develop from the cells of the myelin sheath. A tumor is an abnormal growth of tissue that results from the uncontrolled growth of cells. Acoustic neuromas are often called vestibular schwannomas because they are tumors that arise from the myelin sheath that surrounds the vestibular nerve. Acoustic neuromas are considered benign (non-cancerous) tumors since they do not spread to other parts of the body. They 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.
