What is Acoustic Neuroma and how Does it Affect Your Hearing Health?

Acoustic Neuroma

Acoustic neuroma, also known as vestibular schwannoma, are rare noncancerous tumors that push on nerves located in the inner ear, which affects hearing and balance. They develop on the vestibulocochlear nerve, which is the nerve that is connected from your inner ear to the brain and is responsible for the function of your hearing and balance. They slowly grow due to an overproduction of vestibular schwannoma (or Schwann cells). 

This is a rare tumor that is typically found in middle-aged individuals, between the ages of 30 and 60. They affect women more than men. It is diagnosed through hearing tests and imaging tests.

Two Types of Acoustic Neuromas

Unilateral acoustic neuromas: This usually affects one ear. It’s the most prevalent type of acoustic neuroma, and can progress at any age. Acoustic neuroma may be caused by nerve damage from environmental circumstances.  

Bilateral acoustic neuromas: This affects both ears and is hereditary. Neurofibromatosis-2 (NF2) is a problem that affects the makeup of genes.
  
Causes of Acoustic Neuroma
​

• Exposure to loud noises
• Childhood exposure to low amounts of radiation to the head and neck
• A history of benign tumors located in the parathyroid glands in the neck

Symptoms of Acoustic Neuroma

A number of physical issues may arise as a result of tumors growing and pushing against brain structures or cranial nerves. Here are some symptoms: 

• Hearing loss occurring in the ear that is affected
• Inability to hear high frequency sounds
• Dizziness and balance issues
• Feelings of fullness in the ear
• Tinnitus heard in the side where the tumor is located
• Facial numbness, tingling, or paralysis of facial nerves
• Struggling to swallow
• Headaches
• Being uncoordinated
• An awkward gait 
• Mental confusion

To lower the risk factors of acoustic neuroma, be mindful of loud noise exposure. Symptoms of these tumors can be similar to issues with your middle or inner ear, which makes it difficult to diagnose. Procedures prior to a diagnosis include an exam for your ears and a hearing test.

A computerized tomography (CT) and magnetic resonance imaging (MRI) scan can aid in figuring out the location and size of the tumor. An early diagnosis can give you the best chance for a successful treatment. Be sure to wear hearing protection if you do need to get an MRI scan.
