Acoustic neuroma - a benign tumor that develops from cells of developing vestibular portion of the auditory nerve. Auditory nerve consists of two parts: a branch of the snail, which, as its name implies, goes to the cochlea and transmits sound information to the brain and the vestibular nerve, which transmits to the brain information about balance.
The incidence of acoustic neuroma is one case per 100,000 population per year. This tumor is 11 - 12% of all br... Read more »

Manifestations of acoustic neuroma is to reduce the hearing that occurs as a result of compression of the tumor-cochlear nerve. In addition, the tumor can compress the brain stem. In rare cases, this compression can be life threatening in case of large tumor size, as in this part of the brain are the respiratory and vasomotor centers.
The majority of acoustic neuroma - a slowly growing tumor that can develop over several years, until it begins to appear. For... Read more »
