Happy Labor Day!
As a general rule, I've seen time-and-time again where Acoustic Neuroma patients who've had successful radiation treatment will tend to recommend radiation treatment, while AN patients who've had successful microsurgery will tend to recommend microsurgery. It's human nature.
Same with hospitals and physicians. If a doctor only performs microsurgery for a living, then it's only natural for him to tend to recommend microsurgery. After all, it's what he's trained to do and it's what he's comfortable doing. Likewise with radiation. It's the same situation. It's only natural that people will have a bias.
For me, I'm biased towards radiation. Dr. Sheehan successfully radiated my 1.8 cm Acoustic Neuroma without cracking my skull open. I think that's amazing. I've researched the pros-and-cons online for 8 months day-and-night before I made the decision. I think it's a crime to have microsurgery if an AN is under 1cm and is ideally located, but then again, I am not doctor and that is purely my opinion. Like everyone, I have my bias.
Dr. Michael Seidman, a prominent microsurgeon who spoke at my local ANA support group meeting last October, said he wouldn't even let his own adult son have radiation treatment unless it was clearly under 1cm. In Dr. Seidman's opinion, any Acoustic Neuroma over 1cm should be surgically removed unless you're very elderly or some other extenuating circumstance.
Keep in mind, there have been several successful radiation treatments for Acoustic Neuromas 3.5 cm and under. It all depends on who you talk to, and what statistics you follow, and how you interpret those statistics.
Many doctors who specialize in the same field will disagree strongly on the proper course of treatment. For example, my Acoustic Neuroma was fast growing. 4-out-of-5 radiation specialists highly recommended radiation for me; however, one world-renowned surgeon was strongly against radiation treatment in favor of microsurgery.
A benign Acoustic Neuroma that continues to grow is just as deadly if it's untreated. As far as age, I would consult with the radiation specialists They have treated teenagers. I've even seen little kids successfully treated with Proton Beam therapy. Get the facts from the experts and the stats. Regardless which treatment plan you select, you will likely have to monitor the results for the rest of your life in some capacity with lifelong MRI's. There are unsuccessful radiation treatments, just like there are tumors that unfortunately grow back after they "got it all" with surgery.
Keep in mind anyone can "cheerlead" or "sugarcoat" a treatment plan, but at the end of the day the very real possibility of serious lifelong complications do exist. The AN patient is the one that has to live with the consequences. There are no "do overs."
Supporting people with facts and statistics has its place; however, I can't stress enough how important it is to find the most highly qualified team of doctors who specifically treat Acoustic Neuromas and who work at the highest volume "centers-of-excellence" for Acoustic Neuromas who offer the highest success rates. I believe I paraphrased the ANA motto, which says a lot.
The Lasik surgery was a great example, as well as the selecting a qualified auto mechanic example that was featured in the ANA Notes newsletter. Highest volume. Highest success rates. Highest qualifications (specifically regarding Acoustic Neuromas).
Faith and positive thinking are hot topics. If someone is an atheist, do they have a less successful outcome? I think it's fantastic to question your team of doctors until they can't take it anymore. I wouldn't want to blindly put my trust and faith in my doctor. For example, look at Dr. Hrayr Shahinian who just recently had his license revoked. It's good to question authority.
There are no crystal balls. Even the very best surgeon in the world will likely tell you that he too will cut future facial nerves. It's inevitable. Even if the stats/risk are in your favor and under 5% , it's 100% if it happens to you.
The decision-making process is one of the hardest times to go through. Best wishes and good luck in your search.
Warm regards.
