What Is Acoustic Neuroma?

Acoustic neuromas are slow-growing, noncancerous tumors that develop along the branches of the eighth cranial nerves, also called vestibulocochlear nerves. These nerves extend from the brain into the inner ear and are crucial for both hearing and balance. Acoustic neuromas arise from schwann cells, which wrap around and support nerve fibers, hence their other name, vestibular schwannoma.
