Doctors in Maryland have successfully removed a tumor that they discovered had teeth from a 4-month-old boy’s brain.
An acoustic neuroma is a tumor that grows from the nerves responsible for balance and hearing. The outer ear funnels sound down the ear canal to the eardrum, which vibrates three tiny bones called ossicles (malleus, incus, and stapes) in the middle ear (Fig.
An acoustic neuroma, also called vestibular schwannoma, is a benign, slow-growing tumor that arises from the Schwann cells forming the sheath (covering) of the vestibulocochlear nerve. The doctor will ask about your personal and family medical history and will perform a complete physical examination. Electronystagmography (ENG) is a test that evaluates your balance by detecting eye movements while stressing your balance in various ways.
Magnetic Resonance Imaging (MRI) is a noninvasive test that uses a magnetic field and radiofrequency waves to give a detailed view of the soft tissues of the brain. Computed Tomography (CT) is a noninvasive test that uses X-rays and a computer to view anatomical structures within the brain. Auditory Brainstem Response (ABR) is a test that checks the hearing pathway to the brainstem. The treatment that is right for you will depend on your age, general health, hearing status, and the tumor size. Acoustic neuromas that are small and associated with few symptoms may be observed with MRI scans every year until tumor growth or symptoms change.
There are several surgical approaches to opening the skull (craniotomy) and removing the tumor (Fig. Outcomes of surgery depend on the size and adherence of the tumor, the use of cranial nerve monitoring, and the skill of the surgical team.
Complications of surgery may include facial weakness or paralysis, cerebrospinal fluid leak, persistent headache, meningitis, and stroke.
The two main radiosurgery technologies are the Leksell Gamma Knife and linear accelerator systems, such as the BrainLab Novalis. Complications after radiation may include hearing loss, facial weakness, facial sensory loss, radiation necrosis, and brainstem injury. Clinical trials are research studies in which new treatmentsa€”drugs, diagnostics, procedures, and other therapiesa€”are tested in people to see if they are safe and effective. Coping with the possibility of hearing loss and facial paralysis and deciding which treatment is best for you can be difficult. Hearing preservation is an important goal for patients with an acoustic neuroma, although it is not always possible.
Patients with NF-2 can develop bilateral acoustic neuromas, and many may eventually lose hearing in both ears. If you have questions, please contact Mayfield Brain & Spine at 800-325-7787 or 513-221-1100.

The Mayfield Clinic treats more than 160 patients with acoustic neuroma and neurofibromatosis (NF-2) a year.
We are one of the few acoustic neuroma treatment centers to offer all available treatment options: surgery, radiosurgery, and observation as well as hearing restoration (BAHA, auditory brainstem implant), and balance and facial restoration treatments. The team includes two otolaryngologists, two neurosurgeons, two neurotologists, and two radiation oncologists. Advances in technology give Mayfield’s neurosurgeons unprecedented access to brain tumors.
March 2016: Mario Zuccarello, MD (neurosurgeon) and Ravi Samy, MD (otologic surgeon) team up to discuss hearing preservation in acoustic neuroma surgery. Ringing in the ears: Medically called tinnitus, this can arise in any of "the four sections of the ear" -- the outer ear, the middle ear, the inner ear, and the brain -- and can be due to many causes including ear infections, fluid in the ears, Meniere syndrome (the combination of tinnitus and deafness), some medications such as aspirin and other nonsteroidal antiinflammatory drugs (NSAIDs), aging, and ear trauma (such as from the noise of planes, firearms, or loud music).
A HAIRDRESSER with a rare brain tumour has been left with robotic voices ringing in her ears making people sound like her greatest childhood fear - daleks.
An acoustic neuroma expands out of the internal auditory canal, displacing the cochlear, facial, and trigeminal nerves located in the cerebellopontine angle. As the tumor grows, it expands from its origin inside the internal auditory canal out into the space between the brainstem and the bone known as the cerebellopontine angle. The most common first symptom is hearing loss in the affected ear, which often goes unrecognized or is mistaken for a normal change of aging. No environmental factor (such as cell phones or diet) has been scientifically proven to cause these tumors. During the test you will wear earphones and hear a range of sounds at different tones directed to one ear at a time. During ENG, eye movements are recorded with small electrodes placed on the skin around the eyes. A contrast agent called gadolinium may be injected into the bloodstream during scanning to make tumors more visible.
It is especially useful for viewing changes in bony structures such as widening of the internal auditory canal.

Electrodes on the scalp and earlobes capture the brain's responses to clicking noises heard through earphones. Three surgical approaches to an acoustic neuroma: suboccipital, translabyrinthine, and middle fossa. The medical literature reports vary, but overall, facial movement is preserved in more than 90% of patients, and useful hearing is preserved in 20-80%.
The Acoustic Neuroma Association collects and publishes outcomes data from member surveys on their Web site. All NF-2 patients with bilateral acoustic neuromas should learn sign language before deafness occurs. Dizziness is common and will persist until the opposite ear can compensate and stabilize, usually within 1 to 4 months. The House-Brackmann Scale is used to evaluate facial nerve function before and after treatment (Fig. Periodic MRI scans (every 1 to 2 years) and hearing tests are important for long-term monitoring. Conservative management of 386 cases of unilateral vestibular schwannoma: tumor growth and consequences for treatment.

Long-term quality of life in patients with vestibular schwannoma: an international multicenter cross-sectional study comparing microsurgery, stereotactic radiosurgery, observation, and nontumor controls. Facial Nerve Outcome and Tumor Control Rate as a Function of Degree of Resection in Treatment of Large Acoustic Neuromas: Preliminary Report of the Acoustic Neuroma Subtotal Resection Study. Our affiliation with the University of Cincinnati Brain Tumor Center and the Precision Radiotherapy Center provides patients with care from a multidisciplinary team of doctors. Audiologists, rehabilitation specialists and physical therapists are also part of the team.
In rare situations, tinnitus may also be due to an aneurysm or an acoustic neuroma (a benign tumor on the acoustic nerve). The pear-shaped tumor can continue to enlarge, compressing the trigeminal nerve, which is responsible for facial sensation.
Small tumors, which are typically limited to the bony canal, cause hearing loss in one ear, tinnitus (ringing in the ears), and unsteadiness or dizziness. Acoustic neuromas can be sporadic or caused by an inherited condition called neurofibromatosis type 2 (NF-2).
Type 2 can cause acoustic neuromas on both the left and right sides, creating the possibility of complete deafness if the tumors grow unchecked.
This will include checks for mental status and memory, cranial nerve function (sight, hearing, smell, tongue and facial movement), muscle strength, coordination, reflexes, and response to pain. Alternatively, eye movements may be recorded by videonystagmography (VNG), using an infrared video camera mounted inside goggles that you wear. MRI is useful in evaluating lesions and their effects on surrounding brain structures (Fig.
In 40% to 50% of observed patients, tumor growth or progression of symptoms will prompt the need for surgery or radiosurgery.
While total tumor removal may result in a cure, it also carries a higher risk of hearing and facial nerve damage. The choice of a particular approach depends on the tumor size, tumor position, and hearing status.
This approach may be used for all tumor sizes, but especially large ones, while preserving facial nerve function and useful hearing if possible. Rates of success on postoperative hearing preservation and facial function are inversely related to tumor size. Radiation can cause scar tissue to develop around the tumor and facial nerve, making surgical removal more difficult should the tumor grow back. Information about current clinical trials, including eligibility, protocol, and locations, are found on the Web. The Gardner-Robertson Scale is used to measure useful hearing (1=good, 2=serviceable) (Fig. An auditory brainstem implant (ABI) can be inserted during surgery to provide a sensation of hearing by bypassing the cochlea and directly stimulating the brainstem. Persistent problems with balance, dizziness, or vertigo may require treatment with vestibular rehabilitation. Type 2 (NF-2) tumors grow on spinal and cranial nerves and can cause bilateral acoustic neuromas. This information is not intended to replace the medical advice of your health care provider. Woodwind players are more likely to experience tinnitus than other orchestral players, probably because they usually sit just in front of the brass.

The vestibulocochlear nerve (eighth cranial nerve) is responsible for relaying hearing and balance signals from the inner ear to the brain. As the tumor expands, hearing loss may worsen, facial weakness may occur, and balance problems (disequilibrium) may occur. Sporadic tumors occur 95% of the time, while 5% of acoustic neuromas are associated with NF-2. The presence of bilateral acoustic tumors affects the choice of treatment, as hearing preservation is a prime objective. The test can detect whether you have hearing loss that is sensorineural (from nerve damage) or conductive (from eardrum or ossicle damage). Because patients and acoustic neuromas differ, it is important to seek treatment at a medical center that offers the full range of options, including surgery, radiosurgery, and hearing or facial rehabilitation. Observation may be the best option for older patients with other health conditions or patients with a tumor in their only hearing ear. During tumor removal, a probe is used to stimulate and monitor the nerves and brainstem function. Delayed hearing loss may occur after surgery in 30-50% of patients who had useful hearing immediately after surgery.
Using highly focused radiation beams, radiosurgery works by damaging the DNA inside cells and making them unable to divide and reproduce. The device does not enable the full range of hearing, but it does provide increased noise awareness.
If a patient has facial weakness after treatment, eye care consists of artificial tears and lubricant until facial nerve function returns.
As the fluid moves, thousands of hair cells are stimulated, sending signals along the cochlear nerve, which are processed as hearing in the brain.
Large tumors can compress the brainstem (causing imbalance) and the trigeminal nerve (causing facial numbness). A neurosurgeon, otologic surgeon, and radiation oncologist work as a team to treat acoustic neuromas. Because acoustic tumors grow slowly, small remnants of tumor capsule may be left attached to critical nerves. Partial-removal techniques have higher rates of hearing and facial function preservation immediately after surgery; however, a recent long-term study revealed that subtotal resection had a three-fold higher rate of tumor regrowth and no long-term impact on facial nerve function or hearing [8]. The aim of radiation therapy is to maximize the dose to abnormal cells and minimize exposure to normal cells (Fig. Most patients are able to hear noises, such as a ringing telephone, but the degree of hearing usefulness can vary greatly. If a patient has facial paralysis 1 year after surgery, the chance of further recovery is reduced. Our personal experience confirms that the art of removing an acoustic neuroma involves a definite learning curve.
Attached to the cochlea are three semicircular canals positioned at right angles to each other. As brainstem compression becomes severe, the fourth ventricle collapses and hydrocephalus results, causing persistent headache and visual problems.
Partial or near-total removal has been advocated to reduce the chances of facial nerve damage.
An audiologist or speech therapist can help you learn tips for coping with one-sided deafness. Consultation with an ENT surgeon who specializes in facial plastic and reconstructive surgery is recommended. It takes a significant period of time to develop the microsurgical technique necessary to do it well. Certain types of hearing aids called CROS (Contralateral Routing of Sound) and BAHA (Bone-Anchored Hearing Aid) may be helpful. Getting the best results also requires having access to monitoring techniques that allow you to evaluate facial nerve, hearing, and brain function during surgery. Electrical signals from the semicircular canals are carried to the brain by the superior and inferior vestibular nerves (responsible for balance). These hearing aids take sound that would normally enter the non-hearing ear and route the signal to the hearing ear. The cochlear and vestibular nerves form a bundle inside the bony internal auditory canal before exiting to reach the brainstem.
The facial nerve (seventh cranial nerve) is responsible for moving the muscles of the face. The close relationship of the vestibulocochlear and facial nerves explains why facial weakness can occur when an acoustic neuroma grows (Fig.
Likewise, facial sensation and feeling is controlled by the trigeminal nerve (fifth cranial nerve) and can be affected by large tumors.
