A person points to their ear, where acoustic neuromas would be located

With review and feedback from CEENTA Neurotologist Brendan O’Connell, MD (SouthPark)

Hearing loss, tinnitus, and other ear-related symptoms can stem from many conditions. One lesser-known but important cause is an acoustic neuroma, a type of noncancerous tumor that affects the inner ear.

What is an acoustic neuroma?

An acoustic neuroma, also called a vestibular schwannoma, is a slow-growing, benign tumor that forms on the nerve responsible for hearing and inner ear function.

This nerve connects the inner ear to the brainstem, carrying signals that help your brain interpret sound. Because of its location, even a small growth can impact hearing and nearby nerve structures over time.

Most acoustic neuromas affect only one side, though in rare genetic cases (such as neurofibromatosis type 2), they can occur in both ears.

What are the symptoms of an acoustic neuroma?

Symptoms often develop gradually and may be mistaken for more common ear conditions at first.

Typical signs include:

  • Hearing loss, often in one ear
  • Tinnitus (ringing or buzzing sounds)
  • A feeling of fullness or pressure in the ear

As the tumor grows, it may affect nearby nerves. Larger tumors can potentially impact facial movement or press against structures in the brain, making early evaluation important.

What causes acoustic neuromas?

Most cases occur sporadically, meaning there is no clear inherited cause.

A smaller number are linked to neurofibromatosis type 2 (NF2), a genetic condition associated with tumors affecting nerve tissue.

How are acoustic neuromas diagnosed?

Accurate diagnosis is essential for determining the right treatment plan.

Evaluation typically includes:

  • A detailed medical history and symptom review
  • Hearing tests performed by an audiologist
  • MRI imaging with contrast, which is the gold standard for confirming diagnosis

These steps help ENT specialists determine the size, location, and progression of the tumor.

How are acoustic neuromas treated?

Treatment depends on several factors, including tumor size, growth rate, symptoms, and overall health.

Options may include:

  • Observation (watchful waiting) for small, slow-growing tumors
  • Stereotactic radiation therapy to control growth
  • Surgical removal, especially for larger or symptomatic tumors

After treatment, some patients may benefit from hearing solutions such as bone-anchored devices or other assistive technology.
