What is acoustic neurinoma?
Acoustic neurinoma is a non-cancerous tumor that may develop from an overproduction of Schwann cells that press on the hearing and balance nerves in the inner ear. Schwann cells are cells that normally wrap around and support nerve fibers. If the tumor becomes large, it can press on the facial nerve or brain structure.
What are the symptoms of acoustic neurinoma?
The following are the most common symptoms of acoustic neurinoma. However, each individual may experience symptoms differently.
When a neurinoma develops, it may cause any/all of the following:
The symptoms of acoustic neurinoma may resemble other conditions or medical problems. Always consult your physician for a diagnosis.
What are the different types of acoustic neurinomas?There are two types of acoustic neurinomas:
How are acoustic neurinomas diagnosed?
Because symptoms of acoustic neurinomas resemble other middle and inner ear conditions, they may be difficult to diagnose. Preliminary diagnostic procedures include ear examination and hearing test. Computerized tomography (CT) and magnetic resonance imaging (MRI) scans help to determine the location and size of the tumor.
Early diagnosis offers the best opportunity for successful treatment.
Treatment for acoustic neurinoma:Specific treatment for acoustic neurinoma will be determined by your physician based on:
Treatment may include surgery to remove small acoustic neurinomas. Surgery for larger tumors is complicated by the probable damage to hearing, balance, and facial nerves. Another treatment option is radiosurgery using carefully focused radiation to reduce the size or limit the growth of the tumor.
