Acoustic Neuroma
Medical Questions » Acoustic Neuroma
| Name: Acoustic Neuroma |
| Also known as: Acoustic Neurinoma |
| A usually benign (non-cancerous) tumor of the insulating sheath which covers the acoustic nerve (nerve which conducts the sense of hearing to the brain) which often develops at the point where the nerve passes through
a small hole in skull to enter the brain. |
Causes of Acoustic Neuroma
Not known. |
Symptoms of Acoustic Neuroma
A ringing noise, followed by deafness in the affected ear are the early symptoms. As it increases in size other symptoms may include pain, dizziness and, because of pressure on other nearby nerves that supply the eye, a lack
of tears in the eye and double vision. Headache does not occur until the tumor is very large. |
Tests for Acoustic Neuroma
A CT scan can usually show the tumor accurately. |
Treatment for Acoustic Neuroma
Surgical removal of the tumor in a very intricate operation.
|
Complications of Acoustic Neuroma of its treatment
Removing larger tumors may result in unavoidable permanent deafness and possibly other nerve damage. |
Likely Outcome of Acoustic Neuroma
The smaller the tumor at the time of surgery, the better the final result. Tumors less than 2 cm. in diameter can normally be removed without any problem. |
