Post-surgery regrowth - second surgery or radiation?
RGG:
Hello, I had retrosigmoid surgery for my initial 3x2 cm AN in 2017, and at the time the surgeon thought he removed it completely. Unfortunately, my follow-up MRI in 2020 showed a new enhancement at the end of the auditory canal, and this has grown very slowly over the last three years and now stands at around 7 mm. My surgeon said he doesn't think I should do a second surgery, and is sending me for a radiation referral.
Has anyone had follow-up surgery after regrowth from a first surgery? Are there reasons why a second surgery is more difficult? I'm a little worried about the long term effects of radiation (I'm in my early 40's), and the fact that if it fails I'll need surgery anyway. I'm thinking if I should get a second opinion to see if it can't be removed completely with translab and not have to worry about it anymore.
Thanks for any advice or personal experience,
Rumen

I have a pretty similar situation. Surgery in 2011 and now I have regrowth. Its been monitored for a while and is now ready for action to be taken. I am going the radiation route, but have similar concerns. I'm in my mid 30s. But for me, weighing all the pros and cons, I think radiation is the choice for me.
Maybe contact Dr. Link at Mayo for an opinion of your case.
Sending my best!

I had my procedure 8 months ago, so I dont have personal experience with regrowth (yet!). However, your assessment to get a 2nd opinion (and 3rd and 4th and 5th) opinion is an excellent one given the high variability in treatment overall and no standards of care ! I would suggest including UCSD (Friedman/Schwartz) if you attain other opinions. My understanding is that they treat the most patients in the country with AN. Let us know what recommendations you receive.

Hi RGG,
You asked about if there were reasons why a second surgery might be more difficult. I am certainly not a surgeon, and I have no clue when it comes to Acoustic Neuroma surgeries. But having worked in a hospital for many years, I do know that for some procedures, patients developed scar tissue which sometimes made the second surgery more difficult than the first.
Again, I do not know if this is true with acoustic neuroma surgery, and I would have no idea if the original surgeon was not able to remove all of the acoustic neuroma, if it's possible that scar tissue would have developed around the part that was left behind. And I don't know if radiation could penetrate the scar tissue and be effective?
But you are asking excellent questions, and I think you should ask them to your neurosurgeon and to other specialists you might consult. What I have learned is that if you ask a neurosurgeon about radiation, many of them will play down the effects of radiation. And if you ask someone who specializes in radiation for acoustic neuromas, some of them will play down the effects of surgery. That's why I appreciate the 'team' approach that some hospitals have where acoustic neuroma specialists in both surgery and radiation discuss your situation together. Their answers are more balanced in my opinion.
But again, you are asking the right questions.
Best wishes on your journey!
Don

I don't think any doctor will guarantee that he can completely remove an AN. Sometimes it is stuck to a nerve and they have to leave some in so as not to damage the nerve. I have heard of people on this forum who had regrowth and went for a second AN surgery. So it has been done before. Let me know if you want me to try and find that person.
