ACOUSTIC NEUROMAS

What is the Condition about:

Acoustic neuromas, also known as vestibular schwannomas, are noncancerous tumors that develop on the vestibulocochlear nerve, which connects the ear to the brain. These tumors can cause hearing loss, tinnitus, vertigo, and balance problems.

How I investigate the Condition:

I will perform a physical exam and evaluate the patient's medical history. Imaging tests such as MRI or CT scans are necessary to confirm the presence of an acoustic neuroma.

What treatment options are available:

Treatment options for acoustic neuromas depend on the size and location of the tumor and the patient's overall health. Options may include observation, radiation therapy, or surgery to remove the tumor.

What is Vestibular Schwannoma?

Vestibular Schwannoma (Acoustic Neuroma) is a noncancerous and usually slow-growing tumour that develops on the main nerve that conveys hearing and balance signals from the inner ear to the brain. As it grows, it can lead to hearing loss and tinnitus in one ear, vertigo or loss of balance and facial numbness or weakness. Rarely, it can grow large enough to press on the brain, affecting vital functions.

What causes Cholesteatoma?

Vestibular Schwannoma is related to problems in a gene on chromosome 22. The cause of the fault is not understood. It can be inherited in a rare disorder, neurofibromatosis type 2, which creates the growth of tumours on the hearing and balance nerves on both sides of the head and on other nerves as well.

How is Vestibular Schwannoma treated?

The treatment of vestibular schwannoma depends on several factors including the size and rate of growth of the tumour and the patient’s age and general health. In many cases the tumour can be observed with serial MRI scans, sometimes for many years, to see if it is growing. If the tumour requires intervention, then the management options include specialised stereotactic radiotherapy to stop the tumour growing, or surgery to remove the tumour.
