The information provided here is designed to be a brief introduction to the causes, symptoms and management of acoustic neuromas (vestibular schwannomas) and other skull base tumours. We are recommending a number of UK sources of detailed and up to date information on skull base tumours such as acoustic neuroma. However, please always speak to your doctor about any questions you have.
Some commonly asked questions and links to further information:
What is an acoustic neuroma (Vestibular Schwannoma)?
An acoustic neuroma (vestibular schwannoma) is one of a group of tumours commonly known as skull base tumours. These tumours are usually benign so do not spread to other parts of the body, but if they grow too large, or depending on the location of the tumour, they will need treatment. Acoustic neuromas (vestibular schwannomas) develop from the Schwann cells which form the myelin sheath that wraps around the axons of nerve cells. The axons carry messages from the nerves to the brain. The tumour grows into the canal which carries the axons of three nerves, the auditory nerve, the vestibular (balance) nerve and the facial nerve, between the ear and the brain (as illustrated in the picture above). As the tumour grows it puts pressure on these nerves which can lead to symptoms which may include:
- Loss of hearing
- Problems with balance
- Facial weakness
Acoustic neuromas are not common, they account for about 5% of all brain tumours, and they usually grow very slowly. The tumour may have been present for a number of years before any symptoms are noticed. Other tumours such as meningiomas and facial nerve tumours may also arise in the skull base and may present with similar symptoms

What is a meningioma?
A meningioma is a tumour of the meninges, which is the name given to the protective lining of the brain and the spinal cord. Meningiomas are almost always benign and do not spread. They can occur in any part of the brain or spinal cord but the commonest sites are at the surface of the brain, either over the top or at the skull base. Meningiomas in the skull base may have similar symptoms to acoustic neuromas and will probably require a similar management plan.

What are the treatment options for Acoustic Neuroma (Vestibular Schwannoma) and other skull base tumours?
- There are three approaches to the management of skull base tumours.
- These are:
- ‘Watch, Wait and Rescan’ (monitoring) – this may be suggested following diagnosis if the tumour is small.
- Radiotherapy or radiosurgery
You will be involved in the decision about which treatment would be most appropriate for you.
You will find up to date information about all the treatment options on the following websites:
Preparing for your appointment
Following a diagnosis such as acoustic neuroma you will be referred to a specialist consultant. To get the most out of the appointment it is a good idea to prepare yourself well. This helps both you and the specialist you are seeing.
Here are some things you might like to think about and note down before you go:
- What do you want to tell the doctor?
- What are your symptoms?
- When did they start?
- What impact are they having on your life?
- What medication are you taking?
- What do you want to ask the doctor?
- What does the diagnosis mean?
- What treatments are available?
- What are the pros and cons of the different treatments?
- What will happen if I don’t have treatment?
- Where can I get more information?
- Is there any support available?
- Do you want to take someone with you?
- It may be important for a member of your close family or a friend to fully understand what is happening
- Another person may pick up more from the consultation or ask the questions you have not thought of.
During the appointment
- You may find it difficult to take on board all that you are told:
- so ask for written information
- the person who is with you may remember more than you do
- find out who you can contact if you have more questions
Making your decision
Once given a diagnosis and possibly a choice of management options you may then be faced with making a decision about treatment or management of your skull base tumour. The decision will be a shared decision with the clinical team who will give you information about the various choices and sometimes make recommendations. However, often it is up to you to decide the best choice for you and your family. Hopefully this guide can help you with that process.
This decision may feel very difficult especially if there is not obvious choice.
These are some things that can help with the decision making process
- Do you need more information?
- You can ask the clinical team that are looking after you for more information.
- Search for information on the internet – try to stay with reputable sources – we have provided some reliable sources on this website.
- Who can help me?
- Talk to the clinical team
- Talk to family and friends
- Talk to people who have made the decision before you – this maybe via a website like ours and we also offer the opportunity to speak with one of our members on the phone.
- However remember that everyone’s experience will be different
If you are still not sure it may be helpful to write it all down
- You can make a list of the options available to you and the reasons to choose a particular option or to avoid that option. You can then identify the ones you feel are most likely to happen and how important each of these are to you.
- for example if it is important to you that the tumour is removed then this will be a high score on the reasons to choose surgery,
- whereas if the idea of surgery frightens you, fear of the operation will score high on the reasons to avoid surgery.
- you may then be able to identify the options with the choices that matter most to you and are most likely to happen, and those that you most wish to avoid.
Your final decision will be made in conjunction with the clinical team looking after you, but it is important that you are clear about your options and what is important for you.
