Acoustic Neuroma

Acoustic neuroma is a non-cancerous tumor that develops on the nerve that connects the ear to the brain. The tumor usually grows slowly. As it grows, it presses against the hearing and balance nerves. At first, you may have no symptoms or mild symptoms. They can include

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

If the tumor stays small, you may only need to have it checked regularly. If you do need treatment, surgery and radiation are options. If the tumors affect both hearing nerves, it is often because of a genetic disorder called neurofibromatosis. The tumor can also eventually cause numbness or paralysis of the face. If it grows large enough, it can press against the brain, becoming life-threatening.

Acoustic Neuroma on Wikipedia

'''Acoustic neuroma''' (or '''Vestibular Schwannoma''') is a benign tumor of the acoustic nerve (more properly the vestibulocochlear nerve) just after it has left the brainstem, in the pontine angle. Associated symptoms are unilateral sensorineural hearing loss/deafness and vertigo. Larger tumors can compress local structures such as the facial nerve, and lead to local symptoms such as hydrocephalus. While most cases occur sporadically, rare cases may be attributable to neurofibromatosis (type 2).

Treatment

Indicated treatments for acoustic neuroma include surgically removal and radiotherapy. Because these neuromata grow so slowly, a physician may opt for conservative treatment beginning with an observation period. In such a case, the tumor is monitored by annual MRI to monitor growth. Records suggest that about 45% of acoustic neuromata do not grow detectably over the 3-5 years of observation. In rare cases, acoustical neuromata have been known to shrink spontaneously. Oftentimes, people with acoustic neruromata death of other causes before the neuroma becomes life-threatening. (This is especially true of old age people possessing a small neuroma. Since the growth rate of an acoustic neuroma rarely accelerates, annual observation is essential. Acoustic neuromata may cause either gradual or—less commonly—sudden hearing impairment. However, the surgical and radiotherapy treatments are even more dangerous to the hearing in the affected ear.

Surgery

The surgery is done by several approaches and is associated with high incidence of complications and quality of life issues - but it often removes the tumor without recurrence. The vestibular system nerve is usually removed on the operated side, resulting in severe imbalance, vertigo and dizziness. However, vestibular function improves rapidly due to compensation ...   [ Read More ]
