Acoustic Neuroma Treatment

What are the Causes of Acoustic Neuroma?

The exact cause of acoustic neuromas is not well understood. However, most cases of acoustic neuromas are caused by a genetic change in the Schwann cells. Schwann cells a type of glial cell found in the peripheral nervous system (PNS) work by providing support and insulation to the nerve fibers. Genetic mutations in these cells are thought to be a key factor in the formation of these tumors. Certain genetic conditions, such as neurofibromatosis type 2 (NF2), are associated with an increased risk of developing acoustic neuromas. NF2 is caused by mutations in the NF2 gene, which normally functions to suppress tumor growth. Some studies suggest that exposure to high levels of radiation may also increase the risk of developing acoustic neuromas.

What are the Symptoms of Acoustic Neuroma?

The symptoms of acoustic neuroma can vary based on the size and location of the tumor. Common signs and symptoms include:

• Loss of hearing: Gradual hearing loss in one ear is the most common symptom of acoustic neuroma. 
• Ringing in the ears: Most people may experience tinnitus or a sensation of ringing, buzzing, or hissing in the affected ear.
• Problem with balance: Dizziness, unsteadiness, or vertigo, which may worsen over time.
• Weakness or numbness in the face: The condition can affect the facial nerve causing weakness and numbness on one side of the face.
• Pains in the head: Acoustic neuroma can cause persistent headaches, especially on one side of the face. 
• Ear Fullness or Pressure: Some individuals with acoustic neuromas may experience sensations of fullness, pressure, or discomfort in the affected ear.
• Changes in Vision or Eye Movement: Larger tumors may compress nearby structures, such as the optic nerve or the nerves responsible for eye movement, leading to visual disturbances or double vision.

If you experience any of these symptoms, particularly if they are getting worse over time, it is important to see a healthcare provider to get the right assessment and diagnosis.
