What Is Acoustic Neuroma?

A calm introduction to vestibular schwannoma, where it develops, and why each person’s symptoms and decisions can look different.

Acoustic neuroma is another name for vestibular schwannoma.

01

A tumor of the nerve covering

A vestibular schwannoma is usually a noncancerous tumor that develops from Schwann cells, which support and insulate nerves. It most often grows along the vestibular portion of the eighth cranial nerve, involved in hearing and balance.

02

Why symptoms can vary

Tumor size is only one part of the picture. Location, growth, hearing, balance function, pressure on nearby structures, and the way each person’s nervous system adapts can influence the experience.

  • One-sided or asymmetric hearing change
  • Tinnitus
  • Dizziness, vertigo, or unsteadiness
  • Facial sensation or movement changes in some cases

How it is evaluated

Hearing assessment and MRI are central parts of evaluation. Specialists may also review balance, facial nerve function, tumor location, health history, and changes over time.
