UPDATE IN ACOUSTIC NEUROMAS by: Gil Lederman, M.D. Acoustic neuroma treatment is undergoing a marked revolution. Acoustic neuromas are benign tumors that affect the eighth cranial nerve - a nerve that comes from the brain and is delicately located adjacent to important other structures such as the facial nerve and brain stem. It is a tumor that affects 2,000 to 3,000 Americans annually. Those with acoustic neuromas most frequently have diminished hearing. It is often first noticed because of the decreased ability to use a telephone on the involved side. Ringing in the ear, imbalance and later, pain, numbness or weakness of the face can occur. In the past, treatment remained in the domain of surgeons. Unfortunately, surgery is associated with marked morbidity and occasional mortality. A recent paper from the University of Pittsburgh revealed a complication rate such that more than one-half the patients lost facial function after surgery and a significant number of patients required re-operation for complications from the open surgery. The surgical data was compared to single fraction radiosurgery and a marked diminishment in complications was found using radiation. Now, enhancement of radiosurgery technique has been developed at Staten Island University Hospital. This data was presented at The 77th Annual American Radium Society meeting in Paris. The data shows excellent control of acoustic neuromas with no complications.

43. ACOUSTIC NEUROMA acoustic neuroma. The several names used for this benign tumor include acoustic neuroma, acoustic neuronoma and vestibular schwannoma. http://www.medhelp.org/lib/neuronom.htm

ACOUSTIC NEUROMA Acoustic neuromas are being more frequently diagnosed as those with hearing loss and sometimes other symptoms are obtaining MRIs (Magnetic Resonance Imaging scans) which can show small tumors at an early stage. The several names used for this benign tumor include acoustic neuroma, acoustic neuronoma and vestibular schwannoma. It involves the 8th cranial nerve which has two branches - acoustic and vestibular and under the microscope resembles schwann cells. For that reason, vestibular schwannoma is a synonym. The phrase "benign" generally implies a course unmarked by progression or death. Unfortunately, in the brain, this is not necessarily the situation. Because the brain is so delicate and encased in bone, there is little extra space for unusual growths of any type. The incidence of acoustic neuromas is modest - approximately 1 per 100,000 people per year. It's equivalent to approximately 2,500 people being diagnosed each year in the United States. That is of little relief to those diagnosed. Because MRI can detect lesions which were previously not visible by other means, it is likely that the true incidence is higher. Symptoms include decreased hearing, ringing in the ears and a change in balance. While acoustic neuromas can affect either ear and sometimes both ears, most often it is unilateral.

Find a Doctor Index of Patient Information Clinic Maps and Directions Acoustic Neuroma (Vestibular Schwannoma) Jeffrey P. Harris, M.D., Ph.D. 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 bone of the brain.

Unilateral vestibular schwannomas affect only one ear. They account for approximately 8 percent of all tumors inside the skull; one out of every 100,000 individuals per year develops a vestibular schwannoma. Symptoms may develop at any age but usually occur between the ages of 30 and 60 years. Unilateral vestibular schwannomas are not hereditary. Diagnosis: Early diagnosis of a vestibular schwannoma is key to preventing its serious consequences. In more than 70% of the patients with vestibular schwannomas, hearing loss is the first symptom. In most patients there is a gradual decrease in hearing with difficulty in understanding spoken words often encountered. Ringing in the ears, dizziness, vertigo and headache are less common symptoms. The ringing or "tinnitus" may be constant or change with activity such as exercise. In patients with very large tumors additional symptoms may include weakness of facial muscles, double vision, hoarseness, facial pain or numbness or difficulty swallowing.

An acoustic neuroma is a rare and slow-growing benign tumour that develops on the eighth cranial nerve - the nerve of hearing and balance. It is not cancerous. The eighth cranial nerve has many different names. The part that carries the hearing information may be called the acoustic nerve, the auditory nerve or the cochlear nerve. The part that carries balance information is called the vestibular nerve. Together these parts are called the vestibulo-cochlear nerve or the eighth cranial nerve. The eighth cranial nerve runs through the bone of the skull, carrying both hearing and balance information from the inner ear to the brain. As it passes through the bone, the nerve runs alongside the facial nerve, which carries information from the brain to the muscles of the face.

Acoustic Neuroma BRAIN TUMOR PROGRAM METASTATIC TUMOR PROGRAM MALIGNANT BRAIN TUMOR PROGRAM PITUITARY TUMOR PROGRAM ... BRAIN TUMOR DIAGNOSES INDEX What is an acoustic neuroma? This is a tumor that arises from schwann cells that surround the vestibular nerve. Therefore, the term vestibular schwannoma may be preferred as most are not neuromas and most arise not from the acoustic nerve but from the superior (upper) division of the vestibular nerve. These tumors are benign tumors. How common are acoustic neuromas? These are one of the most common intracranial tumors, comprising 8-10% of tumors. The annual incidence is 0.78-1.15 cases per 100,000 population, resulting in approximately 2300 new cases per year in the United States. What causes acoustic neuromas? As with most other intracranial tumors the exact cause of these tumors is unknown. However, the association of these tumors with Neurofibromatosis Type 2 (NF-2) may lead to some insight into the cause. The incidence of acoustic neuromas in patients with NF-2 is increased, with many patients having these tumors bilaterally. NF-2 is caused by a genetic abnormality on chromosome 22. Therefore, acoustic neuromas that arise in other patients may have a similar abnormality. What are the symptoms of acoustic neuromas?

Three days before D day ! Should you suspect you or someone else of having an Acoustic Neuroma, seek professional medical advice. It all started back on March 7, 1997. I went to my family doctor to see why I was losing my hearing. Being that I was only 35 I was concerned. It had been progressively getting worse for 9 to 11 years. After checking me over he couldn't find anything wrong so he sent me to our local ENT. My first appointment was March 31, 1997. Dr. Bland did all of the initial tests and then took me for a hearing test to see if that would tell us something. The test showed that I had hearing loss in my right ear but didn't show why.

Acoustic Neuroma Program Acoustic neuroma is a non-cancerous tumor located at the base of the brain, originating from one of the balance nerves within the internal auditory canal. As it grows, it presses against several nerves and creates problems in hearing, balance, facial movement and facial sensation. Left unchecked, it may press on the brainstem and become life threatening. The cause of acoustic neuromas in most patients is unknown. According to the Acoustic Neuroma Association, estimates of the incidence of symptomatic acoustic neuroma vary from one in every 200,000 people to one in every 3,500 people. Other studies indicate a more frequent incidence, perhaps as high as 1.5% of the population. Most acoustic neuromas are diagnosed on patients between the ages of 30 and 60.

Acoustic Neuroma Figure 1 is a view of the head from above. The posterior fossa with the intracranial contents of the cerebellum, brain stem and cranial nerves, as well as the temporal bone can be seen. The temporal bone is a part of the skull base. In the temporal bone is the internal auditory canal that allows the cochleovestibular (hearing and balance) nerve and the facial nerve to pass from their intracranial site of origin to either the cochlea (snail like hearing organ), vestibular apparatus (balance organ with the 3 semicircular canals), or the muscles that move the face. Acoustic neuromas most commonly arise in this canal. In Figure 1, a small intracanlicular tumor (colored brown in this illustration) can be seen. In Figure 2 , a larger acoustic neuroma is present. This tumor has grown out of the internal auditory canal into the region known as the cerebellopontine angle, or CPA. The tumor has a characteristic shape, with a root like extension in the internal auditory canal and a globular portion in the intracranial cavity, just touching the brainstem, cerebellum and some of the cranial nerves. Patients may have the same symptoms as when the tumor is in the internal auditory canal or patients may have additional symptoms such as headache. The brainstem compressive stage can be seen in Figure 3 . In this figure the brainstem, cerebellum and cranial nerves are being compressed by the tumor. Acoustic neuromas are almost universally benign (not cancer), so they do not erode into, or replace brain tissue. Rather acoustic neuromas cause damage by taking up space in the intracranial cavity where no extra space exists. Compression and attentuation of vital structures in this stage can lead to increased headaches and numbness of the face.

Acoustic Neuroma and Skull Base Surgery The Bobby R. Alford Department of Otorhinolaryngology and Communicative Sciences Baylor College of Medicine Where is the skull base? The skull base is the bottom part of the skull. While the sides, front, back, and top of the skull are essentially smooth, thin walls of bone, the skull base is dramatically more complex. The skull base is complex because every nerve in the body that carries signals to and from the brain crosses the skull base. Additionally, the large vessels that carry blood to and from the brain run through the skull base. Which types of diseases are treated with skull base surgery? What is skull base surgery? The basic concept of skull base surgery is to approach the tumor from underneath or from the side by removing specific areas of skull base bone. Thus, the tumor can be exposed and with little to no brain retraction. Skull base procedures, for example, may be designed to traverse the bone containing the ear (trans-temporal/trans-petrosal/retrosigmoid approaches), low on the temple beneath the brain (middle fossa approach), around the eye (trans-orbital/orbital-zygomatic/craniofacial approaches), through the nose or paranasal sinuses (trans-sphenoidal/trans-ethmoidal/trans-facial approaches), or from the neck (trans-cervical). Fundamentally, these are minimally-invasive techniques designed to maximize tumor removal while preserving neurological function to the greatest extent possible.

The photographs may be viewed by clicking on the Figure labels of each description. Baylor Otorhinolaryngology link. Go to page bottom Surgery to remove an acoustic neuroma is a delicate, involved procedure. Depending on the skill of the surgeon and the size of the tumor, surgery can take from two and one-half hours to over 12 hours. The following pictures taken through a surgical microscope represent some of the phases in the removal of a 1.8 x 2.0 cm tumor. The "translabyrinthine" approach was used. This approach involves drilling through the mastoid bone behind the ear, and removing the semicircular canals. This surgery will leave the patient without hearing on the affected side and with only one functioning vestibular nerve. The amount of time for the patient to adapt to the use of the remaining vestibular nerve varies, and that length of time is somewhat determined by how severely the nerve is impaired prior to surgery. In general, the more impaired the vestibular nerve is pre-operatively, the shorter the recovery time post-operatively. The translabyrinthine approach is one of the safest approaches for removing an acoustic neuroma, and is the approach preferred in tumors in which hearing preservation is not an issue, and the location and size of the tumor warrant its use.
