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.

ACOUSTIC NEUROMA Timothy C. Hain, MD Please read our Return to Index Page last modified: June 30, 2005 Main Points: 1. Acoustic neuromas are a rare cause of unilateral hearing loss, dizziness, as well as rarely other symptoms related to the brain. 2. The best tests to diagnose acoustic neuroma are audiometry (hearing testing) and MRI scanning of the head with gadolinium contrast. 3. About half of all acoustic neuromas are treated by surgery, about a quarter with radiation (this is increasing), and about a quarter are watched. 4. No matter what method of treatment is used, hearing preservation is very unlikely. Acoustic neuromas, also known as vestibular schwannomas, are non-malignant tumors of the 8th cranial nerve. Most commonly they arise from the covering cells (Schwann cells) of the inferior vestibular nerve (Komatsuzaki and Tsunoda, 2001). There is some difference of opinion about this some sources suggest that they occur equally often in the superior vestibular nerve, and some indicate that they are most common in the superior vestibular nerve. They can also arise within the labyrinth (Neff et al, 2003). They comprise about 6 percent of all intracranial tumors, about 30% of brainstem tumors, and about 85% of tumors in the region of the cerebellopontine angle another 10% are meningiomas. Only about 10 tumors are newly diagnosed each year per million persons (Evans et al, 2005), corresponding to between 2000 and 3000 new cases each year in the US. Another way of looking at this is that an average person has a risk of about 1/1000 of developing an acoustic neuroma in their lifetime (Evans et al, 2005). In patients with hearing asymmetry, it is believed that only about 1 in 1000 has acoustic neuroma (source: NIH), although some report prevalance as high as 2.5% (Baker et al. 2003). The higher prevalence does not correspond to our clinical experience in our

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.

Subscribe now >> Treatment Options for Acoustic Neuromas Loss of hearing is common in older people, but when a younger person experiences a hearing loss, especially on just one side, it could indicate a relatively rare tumor called an acoustic neuroma. Acoustic neuromas usually begin in a tiny, bony tube called the internal auditory canal - the passage carrying nerves and blood vessels between the inner ear, where the hearing and balance mechanisms are located - and the brain. As the tumor grows inside this bony tube and then out against the brain, it distorts adjacent nerves and can affect balance as well as hearing. About 2,000 acoustic neuromas are diagnosed in the United States annually. The good news is that acoustic neuromas are benign (non-cancerous) and usually slow-growing. And in just the past few years, technological advances have significantly improved early diagnosis and expanded treatment options for acoustic neuroma, says P. Ashley Wackym, MD, John C. Koss Professor and Chairman of the Department of Otolaryngology and Communication Sciences at the Medical College of Wisconsin.

Acoustic neuroma From Wikipedia, the free encyclopedia. Acoustic neuroma (or Vestibular Schwannoma ) is a benign tumor of the acoustic nerve (more properly the vestibulocochlear nerve ) just after it has left the brainstem , in the pontine angle . Associated symptoms are unilateral sensorineural hearing loss deafness and vertigo . Larger tumors can compress local structures such as the facial nerve , and lead to local symptoms such as hydrocephalus . While most cases occur sporadically, rare cases may be attributable to neurofibromatosis (type 2). edit Treatment Indicated treatments for acoustic neuroma include surgical removal and radiotherapy Because these neuromata grow so slowly, a physician may opt for conservative treatment beginning with an observation period . In such a case, the tumor is monitored by annual MRI to monitor growth. Records suggest that about 45% of acoustic neuromata do not grow detectably over the 3-5 years of observation. In rare cases, acoustical neuromata have been known to shrink spontaneously. Oftentimes, people with acoustic neruromata die of other causes before the neuroma becomes life-threatening. (This is especially true of

Acoustic Neuromas What is an acoustic neuroma? An acoustic neuroma is a benign tumor that can affect the balance and hearing nerves behind the inner ear. Tumors are classified as benign or malignant based upon their growth characteristics. Benign tumors generally grow slowly and do not spread throughout the body. When they grow, they usually invade or push adjacent structures aside. Unlike benign tumors, malignant tumors like breast cancer, colon cancer, lung cancer and prostate cancer generally grow faster and can spread to other regions of the body. Where are these acoustic neuromas? The internal auditory canal contains three different types of nerves, the hearing, balance and facial nerve. The facial nerve is responsible for conducting information concerning motion of the face on that side. This is the nerve that is responsible for our ability to raise our eyebrows, close our eyes, flare our nostrils and raise the corner of the mouth on that side. It is also responsible for conducting information regarding taste from the front 2/3 of the tongue and also tear production from the lacrimal glands in our eyes. The superior and inferior vestibular nerves (or upper and lower balance nerves) convey information regarding balance function from a number of balance organs including the semicircular canals, utricle and saccule. Peripherally, i.e. closer to the inner ear, the superior and inferior vestibular nerves are coated by a layer of Schwann cells which produce a substance called myelin, which allow efficient conduction of nerve impulses. Centrally, i.e. closer to the brainstem, these nerves are coated by a layer of cells called oligodendroglia, which have the same function as Schwann cells. The junction where the Schwann cells meet the oligidendroglia cells is termed the Obersteiner-Redlich zone. Acoustic neuromas arise from Schwann cells, located near the Obersteiner-Redlich zone, and are more appropriately termed vestibular schwannomas.

Acoustic Neuroma and LASIK, IntraLASIK, PRK, LASEK, Epi-LASIK, CK, P-IOL, RLE, etc. Acoustic neuroma is not usually a contraindication for refractive surgery if it has been either removed or otherwise stabilized, however be sure to tell your refractive surgeon about your condition. Although reduced facial sensation, limited facial expression, and poor balance may occur, these do not directly affect refractive surgery. Acoustic neuroma (sometimes termed a neurolemmoma or schwannoma) is a non-cancerous tissue growth on a nerve leading from the brain to the inner ear. This nerve both transmits sound information and sends balance information to the brain from the inner ear. This nerve and the facial nerve that provides motion of the muscles of facial expression lie adjacent to each other as they pass through a bony canal called the internal auditory canal. The brain is not invaded by the tumor, but the tumor pushes the brain as it enlarges. The slowly enlarging tumor protrudes from the internal auditory canal into an area behind the temporal bone called the cerebellopontine angle. The tumor now assumes a pear shape with the small end in the internal auditory canal. Larger tumors can press on another nerve in the area (the trigeminal nerve) which is the nerve of facial sensation. Vital functions to sustain life can be threatened when large tumors cause severe pressure on the brainstem and cerebellum part of the brain. Most acoustic neuromas are diagnosed in patients between the ages of 30 and 60.
