What to Ask the Doctor if You Have Just Been Diagnosed With Acoustic Neuroma

by Dr. Leanne Haroun & Neil Myers

Hello everyone!  One of our most popular blog-articles on the Schwannoma Survivors & Schwannoma Fighters blog has long been the blog "What to Ask the Doctor if You Have Just Been Diagnosed With a Schwannoma."  But for those who have Acoustic Neuromas / Vestibular Schwannomas - many of the details of what a patient may need to know can differ from those who suffer from the variety of other commonly known Schwannomas.  So, we enlisted to help of our advisor to the page for AN / VS, Leanne Haroun.  Leanne has a unique perspective because she herself had an AN, and she is also a third year student in medical school.  So with her assistance, we'd  like to offer you this blog of useful questions to ask your doctor if you have just been diagnosed with an Acoustic Neuroma / Vestibular Schwannoma.  We hope it helps you in getting the answers you need, and the best possible treatment outcome!
___________________________________________________________________________

1) What is your area of specialization? How many vestibular schwannomas have you operated on?  

Why this question?  It is in your best interest to find a neurosurgeon or ENT who has extensive experience with AN/ VS.  Some neurosurgeons specialize in only nerve tumors of the head, and therefore if one can seek out surgeons who have operated extensively on nerves such as the cranial nerves where AN / VS are found, it gives you the best possible chances at a good outcome, by way of having a surgeon who is a specialist to that area of the body, performing the surgery.  

2) Which surgical approach will you be taking? What are the pros and cons of this approach? Are there other alternatives?

Why this question? There are 3 different approaches: 1) retrosigmoid/suboccipital 2) translabyrinthine and 3) middle fossa. Depending on the goals of the surgery (i.e. hearing preservation in patients who still have functional hearing on the tumor side), there are pros and cons to each approach. Because I did not have any noticeable hearing loss on my right side (where my tumor was located), my surgeon took the retrosigmoid approach, which makes hearing preservation possible. But if you are already deaf on the side of your AN/VS, your surgeon may opt for the translabyrinthine approach.

3) Will you be working with ENT (ear, nose & throat surgeon) to remove my tumor?

Why this question?  Some AN / VS specialist surgeons will work in teams - in some cases a neurosurgeon teamed with an ENT ( Ear, Nose, and Throat specialist).  In other cases an experienced AN surgeon will do the entire procedure. 

4) What are my chances of hearing preservation / facial nerve preservation?

Why this question?  It is possible to suffer some degree of loss of sensation or facial paralysis after the removal of some AN / VS tumors.  So it is in the patient's interest to try to learn just how much the nerve is expected to be affected by the surgery, and what prospects the surgeon gives the patient - given the size and location of the tumor, in the interests of keeping the maximum possible preservation of the facial nerve.  (Leann has written a postscript with further details on this question.   Scroll to the end of the article to read )

5)  How long will the surgery be? How much of the tumor do you expect to remove?

Why this question?  In order to preserve maximum nerve function after the surgery, a significant number of AN / VS 's will be partially removed.  It may be helpful to the patient to know this in advance, and to better understand the surgery, the duration of the surgery, and expectations of results.  

6)  Will I be in the Neuro ICU?

Why this question?  Many Schwannoma surgeries require a short stint in the ICU, often 1 to 2 days after surgery. It is helpful to know if this is expected.

7)  What should I expect after surgery? Potential complications?

Why this question?  It is a simple matter of getting a prospectus as to what might be expected post surgery.  It is helpful to know if you need to plan for rehab, for family or loved ones to assist in your care after surgery - and as well, to know what risks of complications are present.

8)  How long will I need to recover? Do you think I may need rehab? How much assistance will I need at home and for how long?

Why this question?  As stated above, you want to make sure you have the necessary assistance in the days and weeks after surgery.  And knowing what plans the surgeon has for your rehabilitation and recovery can only better assist you in planning and making sure you fully understand the post surgical time period you will experience.

9)  Do you think I could have neurofibromatosis type 2?

Why this question?  Neurofibromatosis type 2 is a genetic condition understood to be present in some patients who have Acoustic Neuromas / Vestibular Schwannomas.  (Leanne has added further notes on this in the postscript to this article.  Scroll to the end of the article to read . )


10)  Will it grow back? What would my options be at that point? 

Why this question?  It is always helpful to know how much of the tumor the neurosurgeon believes he or she can remove.  And in that same light, it is also helpful to know if the surgeon has thoughts on the risks of regrowth even if he or she believes the entire tumor to be removed.  It is certainly in the patient's interest to do their best to plan for the future - including potential means of treatment should a regrowth occur.


Postscript notes

Here are a few further details provided by Leanne Haroun, relative to several of the questions stated above.  These are details she wrote:

For number 4 - I'd like to add this: the goal of any neurosurgeon is to remove as much of the tumor while minimizing any damage to the delicate nerves in that area - mainly the vestibulocochlear nerve and facial nerve.  AN/VSs grow off of the vestibulocochlear nerve, which is responsible for balance and hearing.  Because the tumor grows directly off of this nerve, some degree of hearing loss on the side of the tumor must be anticipated. The facial nerve, which supplies the muscles responsible for smiling and eye closure, sits right above the vestibulocochlear nerve. Because of this, facial nerve damage may be unavoidable as well. In general, the larger the tumor, the higher the chances of damage to the vestibulocochlear nerve or the facial nerve. There is good news though! Today, neurosurgeons are able to directly monitor all of the nerves surrounding the tumor during surgery and because of this, avoidable damage can be minimized.

My tumor was 2.3 cm (considered "moderately" sized) and my surgeon was able to preserve both my hearing and facial nerve function, although my hearing on the right side is definitely not as good as my left side. I can hear in my right ear, but understanding someone if I use my right ear to talk on the telephone is a bit harder as the words sound "fuzzier." Otherwise, it is hardly noticeable.


For number 9 -  NF2 is a very rare genetic syndrome characterized by bilateral AN/VSs as well as other types of tumors of the nervous system. Only around 5% of people with AN/VSs actually have NF2. I only include this question because I myself was worried about this prospect because I was diagnosed with my tumor at a much younger age than normal. Most people diagnosed with AN/VS are between the ages of 30 - 60 and do not have NF2. When you are diagnosed at an age younger than 30 (and especially if diagnosed at 20 or younger), NF2 becomes more of a concern. Therefore, I believe it is prudent to ask about NF2, especially if you are in this younger age bracket.
