Acoustic Neuroma

  • Overview Symptoms Causes Diagnosis Treatment
Overview

An acoustic neuroma is a tumor of the nerve which connects the ear to the brain and is usually a
benign tumor, which means it does not spread to other parts of the body.

Symptoms

The symptoms of acoustic neuroma usually develop from the tumor that presses the adjacent
nerves, nearby blood vessels, or brain structures. As a result of which the most common symptoms
include:

  • Hearing loss (Gradual)
  • Ringing (tinnitus) in the affected ear
  • Unsteadiness, loss of balance
  • Dizziness (vertigo)
  • Facial numbness and weakness
Causes

Acoustic neuromas are usually caused as a result of a malfunctioning gene and another possible risk
factor may be childhood exposure to low-dose radiation of the head and neck.

Diagnosis

Diagnosis is determined by a PET CT or MRI scan of the head which provides images that can confirm
the presence of an Acoustic Neuroma and helps in designing a treatment plan that is best for you.

Treatment

Treatment may vary depending on the size and growth of the acoustic neuroma. If the scans show
the tumor is growing or if the tumor causes progressive symptoms, a non-invasive treatment modality like CyberKnife is suggested.


CyberKnife uses radiation with pin-point accuracy to remove the tumors and stop them from
growing while preserving facial nerve function and possibly preserve hearing. The pinpoint accuracy
of CyberKnife eliminates damage to surrounding healthy tissue.
