An acoustic neuroma is a noncancerous tumor that develops on the main nerve leading from the inner ear to the brain. This nerve is called the vestibular nerve. Branches of the nerve directly affect balance and hearing.
Acoustic neuroma is a rare non-cancerous tumor. It grows slowly from an overproduction of Schwann cells. The tumor then presses on the hearing and balance nerves in the inner ear.
You and your health care team may decide to monitor an acoustic neuroma if it's small and isn't growing or if it's growing slowly. This may be an option if the acoustic neuroma causes few or no symptoms.
WebMD discusses the causes, symptoms, and treatments of acoustic neuroma, a benign tumor in the ear area.
Acoustic neuromas (vestibular schwannomas) are benign (noncancerous) tumors that can affect the nerves that help you hear and maintain your balance. The tumors can grow large enough to be life-threatening by pressing on the part of your brain that manages the flow of spinal fluid.
Acoustic neuromas are tumors that develop from the sheath of Schwann cells. They tend to occupy the cerebellopontine angle and are usually found adjacent to the cochlear or vestibular nerve, either intracranially or extra-axially.
Acoustic neuromas, also known as vestibular schwannomas, arise from the hearing and balance nerve. While some patients have no noticeable symptoms or problems, others complain of dizzy spells, vertigo, trouble hearing, facial numbness, and sometimes weakness and swallowing difficulties.
Anatomy of an Acoustic Neuroma. An acoustic neuroma, known as a vestibular schwannoma, is a benign (non-cancerous) growth that arises on the eighth cranial nerve leading from the brain to the inner ear.
A vestibular schwannoma (also known as acoustic neuroma, acoustic neurinoma, or acoustic neurilemoma) is a benign, usually slow-growing tumor that develops from the balance and hearing nerves supplying the inner ear.
An acoustic neuroma is a benign tumor that develops from the balance and hearing nerves supplying the inner ear. As the acoustic neuroma grows, it compresses the hearing and balance nerves, usually causing one-sided hearing loss, tinnitus, and dizziness or loss of balance.
