Dear mrgrta,

I was newly diagnosed on November 26, had my neurosurgeon appointment on Dec 17, and Gamma Knife on Jan 8.  I personally decided on quick action and could not travel (because I have an echo of sounds in my affected ear and it makes travel super loud and hard--it will take me time to rehabilitate from that symptom, but I am hopeful).  The best option in my area was Gamma Knife--with a world-renowned oncologist and 5-star neurosurgeon.  The medical care team was superb.  They said I could resume normal activities the day after the treatment, but that wasn't the case for me.  I am petite and even the fasting required for the procedure was a challenge to recover from.  I did experience vertigo and fatigue for nine days afterwards; I also may have more hearing loss, but I am back to normal energy levels and the vertigo is gone.  I will have a follow-up MRI in 3 months. Everyone's story is different, and I trust you will make the best decision for you!

Thank you for responding!  I appreciate your effort - and your math!  haha
I posted Chat Gpt response below - just another guesstimate.  It's confusing to me that it is so hard to get actual number.  Hopefully an expert who sees this post can chime in...

FROM CHAT-GPT:  ~1,700–2,000 (estimated)

Incidence: Vestibular schwannomas (acoustic neuromas) occur in roughly 2,500–3,300 people annually in the U.S., based on incidence estimates of about 1.0–1.2 cases per 100,000 population per year and U.S. population figures.

🔪 Surgical Volume — The exact number of surgeries each year isn’t universally tracked in a single report, but large retrospective analyses provide good estimates:
A national analysis of surgical trends from 2001–2014 found that annual surgical resections for vestibular schwannoma declined from about ~2,807 procedures in 2001 to ~1,795 in 2014.

That suggests recent years likely see on the order of about ~1,700–2,000 surgical resections per year in the U.S., given stable incidence but increasing use of non-surgical treatments (e.g., radiosurgery).

Older surgical outcome studies and registries also support similar annual volumes in the low-thousands during earlier decades, consistent with the above trend.

📌 Key Points

Total new acoustic neuroma diagnoses per year in the U.S.: ~2,500–3,300.

Estimated surgical resections per year: ~1,700–2,000 (based on historical surgical volumes and declining trends).

Not every diagnosed patient undergoes surgery—many are managed with observation or radiotherapy, especially for small tumors.

I’ve seen folks with similar questions say they start low with CBD and keep notes on what actually helps them day to day. Quality can vary a lot, so I usually stick to places that make things easy to sort through; sites like www.smokeday.com help me compare options without digging forever. If you’re mixing CBD with other meds, I always ask my doctor first just to keep things smooth.
