Acoustic Neuroma

What is Acoustic Neuroma?

  • A relatively rare yet possibly serious condition requiring diagnosis and treatment. 
  • A typically slow growing and non-cancerous tumor, growing on the 8th cranial nerve that leads from the inner ear to the brain. 
  • A condition typically affecting women more than men and diagnosed between the ages of 30 and 60.

What causes Acoustic Neuroma?

  • The majority occur in sporadic form, for which cause is currently unknown. 
  • A small percentage are inherited based on a syndrome referred to as NF2.

What are the usual symptoms of Acoustic Neuroma?

  • Unilateral hearing loss, particularly at high frequencies. 
  • Unilateral tinnitus, which can cause feelings of fullness in the ear, buzzing, ringing, chirping or roaring. 
  • Balance problems may occur if the acoustic neuroma is allowed to grow.

Diagnosis – your Audiologist will:

  • Perform audiologic testing to carefully evaluate hearing in both ears. 
  • Perform an auditory brainstem response (ABR) test, which measures passage of electrical signals from the inner ear to brainstem pathways. 
  • As necessary, coordinate with your Physician to order an MRI with special material that helps clearly define Acoustic Neuroma, if present.
