What is the most common treatment for acoustic neuroma?

Acoustic neuroma (also called a vestibular schwannoma) is a serious but nonmalignant tumor that develops on the sheath of inner ear’s vestibulo-cochlear nerve, which transmits both balance and sound information to brain.

What is acoustic neuroma (vestibular schwannoma)?

Overview. Acoustic neuroma, also known as vestibular schwannoma, is a noncancerous and usually slow-growing tumor that develops on the main (vestibular) nerve leading from your inner ear to your brain. Branches of this nerve directly influence your balance and hearing, and pressure from an acoustic neuroma can cause hearing loss,…
