Acoustic Neuroma

An acoustic neuroma is a benign tumor that grows on the nerve connecting the ear to the brain. It usually grows slowly and presses against the hearing and balance nerves. If it grows large enough, it can press against the brain and become life-threatening.

Symptoms

• Loss of hearing on one side
• Ringing in ears
• Dizziness and balance problems
• Numbness or paralysis of the face (if tumor grows large)

Causes

The exact cause is not fully understood, but if tumors affect both hearing nerves, it is often due to a genetic disorder called neurofibromatosis.

Diagnosis

Acoustic neuroma can be difficult to diagnose because symptoms are similar to middle ear problems. Ear exams, hearing tests, and scans can show if you have it.

Treatment

If the tumor stays small, you may only need to have it checked regularly.

Medications

• Bevacizumab (for NF2-related cases)
• Icotinib
• Lapatinib
• Everolimus
• Selumetinib
• Brigatinib

When to see a doctor

You should see a doctor if you experience hearing loss on one side, ringing in the ears, dizziness, or balance problems.
