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, ringing in your ear and unsteadiness.
Diagnosis can be made using detailed audiological evaluation followed by radiological evaluation. Treatment widely depends on the size and site of lesion and damaged happed. Generally neurosurgeon and neurotolgist work together to manage the patient.
