Acoustic Neuroma Overview

What Are The Symptoms Of Acoustic Neuroma?

The vestibular nerves transmit sound information to the brain and plays a role in balance. As it grows, acoustic neuromas can negatively impact these two functions. Initial signs of one of these tumors include one-sided hearing loss, tinnitus (ringing in the ear), and dizziness. Vertigo, which is a consistent loss of balance, can also result. If an acoustic neuroma becomes too large, it can place pressure on the brain stem, brain tissue, and other cranial nerves which can lead to neurological problems including impaired facial sensation and whole body function.

Diagnosing Acoustic Neuroma

Along with an ear exam and hearing test, a computerized tomography (CT) scan or magnetic resonance imaging (MRI) procedure are needed to diagnose acoustic neuromas. The auditory brainstem response test is another diagnostic tool that evaluates the transmission of information from the inner ear to the brain. This test can be used to diagnose an acoustic neuroma before hearing loss is observed. Since the initial signs are mild and this kind of tumor is slow-growing, it often is not diagnosed early. It is important to obtain regular ear exams as well as discuss any hearing loss with an audiologist.
