Acoustic Neuroma (Vestibular Schwannoma)

Acoustic neuroma, also called vestibular schwannoma, is a slow-growing, non-cancerous (benign) tumor. It develops on a nerve that runs between the inner ear and the brain. 

While an acoustic neuroma isn't cancerous, it can be life-threatening. If not treated, it can grow large enough to press against your brain stem. 

And if it's not performed by an expert with years of experience, surgery to remove an acoustic neuroma can result in facial paralysis or hearing loss. 

University of Iowa Health Care otologists and neurotologists are among only a few such experts in the country. They are extremely skilled in removing acoustic neuromas without damaging facial nerves or hearing.

The first step in treating an acoustic neuroma is finding out whether it's growing and, if so, how quickly. 

If your tumor is small and not causing significant symptoms, your specialist will likely recommend a second MRI six months after your diagnosis. 

Small, slow-growing tumors usually don't need treatment if they aren't causing problems. An MRI every six to 12 months will track your tumor's growth. 

Surgery may be recommended for patients with smaller tumors if their hearing is excellent and they are interested in trying to preserve their hearing. 

Large acoustic neuromas can damage your hearing as they grow. The ability to save hearing is related to your tumor's size and your hearing level before surgery. 

Depending on where your hearing loss has occurred, your neurotologist might recommend one of the following implanted devices to help you hear better: 

UI Health Care neurotologists are some of the most experienced in the country in the implantation of these devices.
