What is Acoustic Schwannoma?

Acoustic schwannoma, also known as Vestibular schwannoma, is an uncommon cancerous tumour in the nerve connecting the inner ear with the brain. Acoustic schwannoma can lead to hearing loss and unbearable pain in the ear. It can be treated by surgical removal, radiation and regular monitoring by the neurosurgeon specialist.



People with Acoustic Schwannoma often experience the following symptoms or signs:

  • Losing hearing ability
  • Numbness in the face
  • Unsteadiness
  • Vertigo
  • Tinnitus in the ear



The cause of acoustic schwannoma is a malfunction of Chromosome 22(Gene). Chromosome 22 produces a protein that controls the development of Schwann cell.


The main risk factor of acoustic schwannoma is having a parent with the uncommon hereditary issue; neurofibromatosis type 2.


Acoustic schwannoma cannot be prevented. 

How is it diagnosed?

Acoustic schwannoma develops slowly so it may be difficult to detect the tumour at an early stage. Your doctor may conduct the following tests:

  • Hearing test
  • Imaging tests
