Neuroma, acoustic Treatment in Hyderabad


Acoustic neuroma usually arises from Schwann cells that line this nerve and grow slowly or not at all. In rare cases, it can grow quickly and become large enough to press against the brain and interfere with vital functions.


The signs and symptoms of acoustic neuroma are often subtle and can take several years to develop. They’re usually the result of the tumor’s effects on hearing and nerve balance. The pressure of the tumor on nearby nerves that control facial muscles and sensations (facial and trigeminal nerves), nearby blood vessels, or brain structures can also cause problems.

As the tumor grows, it may be more likely that it is causing more noticeable or serious signs and symptoms.

Common signs and symptoms of acoustic neuroma include:

The reasons

The cause of acoustic neuromas appears to be a defective gene on chromosome 22. Usually this gene produces a tumor suppressor protein that helps control the growth of Schwann cells that line nerves.

What constitutes this genetic dysfunction is unclear and in most cases of acoustic neuroma there is no identifiable cause. This defective gene is also inherited from neurofibromatosis type 2, a rare disease in which tumors usually grow on the equilibrium nerves on either side of the head (bilateral vestibular schwannomas).

Risk factors

A distinctive feature of type 2 neurofibromatosis is the development of non-cancerous tumors on the equilibrium nerves on either side of the head, as well as on other nerves.

Neurofibromatosis type 2 (NF2) is known as an autosomal dominant disorder, which means that the mutation can only be passed on from one parent (dominant gene). Every child of an affected parent has a 50:50 chance of inheriting it.


An acoustic neuroma can cause a variety of lifelong complications, including:
