The term acoustic neuroma has been replaced by the more accurate term vestibular schwannoma, but both remain in use. Vestibular schwannomas are very slow-growing and may even stop growing spontaneously and remain very small, causing no symptoms whatsoever. As they are slow-growing tumours, the symptoms often also develop slowly over time and may not be obvious at first. Symptoms caused by vestibular schwannomas are common to many other illnesses and conditions. The symptoms that a vestibular schwannoma can cause are very common in the general population. Remember that vestibular schwannomas are very rare.

An acoustic neuroma is a tumor that grows from the nerves responsible for balance and hearing. These tumors grow from the sheath covering the vestibulocochlear nerve. Acoustic neuromas are benign not cancer and usually grow slowly. Over time the tumor can cause gradual hearing loss, ringing in the ear, and dizziness. Because of their slow growth, not all acoustic neuromas need to be treated. Treatment options include observation, surgery, and radiosurgery. The ear is our organ of hearing and balance.
Acoustic neuroma is the most common type of brain tumor. It is non-cancerous and grows on a tiny nerve that is located near facial nerves between the inner ear and brainstem. An acoustic neuroma occurs on the eighth cranial nerve. It consists of three nerves that link the eardrum to the brain, including the cochlear nerve carries hearing information and left and right nerves carry balance signals from the inner ear to the brain. Schwann cells neurilemma cells protect these nerves.
An acoustic neuroma, also known as a vestibular schwannoma, is a rare benign non-cancerous growth that develops on the eighth cranial nerve. This nerve runs from the inner ear to the brain and is responsible for hearing and balance equilibrium. Although there is no standard or typical pattern of symptom development, hearing loss in one ear unilateral is the initial symptom in approximately 90 percent of affected individuals. Additional common findings include ringing in the ears tinnitus and dizziness or imbalance.
