What is the goal of brain tumor treatment?
The obvious goal of therapy of any benign brain tumor is to eradicate the tumor while preserving neurologic function. There are many factors which come to bear in terms of the success of treatment for these tumors. Acoustic neuromas, because of their location in proximity to delicate brain structures and cranial nerves, are a complicated treatment problem. The treatment of these tumors is best left in the hands of professionals who have a significant experience with their treatment. Experience in dealing with all aspects of treatment is important in order to maximize success and take advantage of all therapeutic options.
Can a tumor be removed?

What is a vestibular schwannoma?
It grows slowly from an overproduction of Schwann cells and is also called a vestibular schwannoma. The tumor then presses on the hearing and balance nerves in the inner ear. Schwann cells normally wrap around and support nerve fibers. A large tumor can press on the facial nerve or brain structures.
How does MRI work?
MRI uses magnetic fields and radio waves, rather than x-rays, and computers to create detailed pictures of the brain. It shows visual “slices” of the brain that can be combined to create a three-dimensional picture of the tumor. A contrast dye is injected into the patient.
Where is the hearing aid implanted?
The bone-anchored hearing aid (Baha) speech processor is a hearing aid that doctors surgically implant under the skin near the ear. The device grows into the skull bone and enhances the bone’s natural transmission of sound.
What is the first test for neuroma?
Hearing test (audiometry): A test of hearing function, which measures how well the patient hears sounds and speech, is usually the first test performed to diagnose acoustic neuroma. The patient listens to sounds and speech while wearing earphones attached to a machine that records responses and measures hearing function. The audiogram may show increased " pure tone average " (PTA), increased " speech reception threshold " (SRT) and decreased " speech discrimination " (SD).
How do cochlear implants work?
Cochlear implants work by bypassing the damaged portions of the ear and directly stimulating the hearing nerve. They generate signals from the auditory nerve to the brain, which recognizes the signals as sound. Cerebrospinal fluid leak is a common problem after surgical removal of an acoustic neuroma.
What Is The Best Treatment for Acoustic Neuroma?
