Hello Clair - I had never heard of this until I read your post and so I can offer you no first hand knowledge of this. I expect you may have researched this on the internut or perhaps the doctor/consultant who has booked you in for this procedure has explained what it is but you seek information from someone who has had this?

I expect someone will be along soon to help you out. In the meantime I wish you success and a speedy recovery once you’ve had the procedure.

Thanks for your message.

I haven’t done a search online as I know I will get myself into it wobble

A Gamma Knife is used to treat Brain tumor by administering high-intensity gamma radiation therapy.amma Knife therapy, like all radiosurgery, uses doses of radiation to kill cancer cells and shrink tumors, delivered precisely to avoid damaging healthy brain tissue.

OK - in that case, perhaps this might help. It is based in what is on the internet (as per @BHAGYODAY message below, but with a bit more information.)

Gamma Knife surgery is a painless, computer-guided form of radiation therapy. This treatment delivers highly focused beams of energy on tumors or lesions in your brain and upper spine. It commonly treats small brain tumors, arteriovenous malformations, trigeminal neuralgia and more.
Despite its name, this procedure isn’t a surgery and doesn’t involve any knives. Gamma Knife gets its name based on the precision of gamma rays. These are high-energy photons (a particle of electromagnetic radiation). Gamma rays are as accurate as a surgical knife to specifically target an area of your brain without cutting into your body.
The goal of Gamma Knife surgery is for the radiation to stabilize, shrink or destroy a tumor or lesion. Gamma Knife surgery can treat small brain abnormalities like:
Brain tumors (cancerous and noncancerous).
Blood vessel abnormalities.
Nerve abnormalities.

For treatment, you will have lay flat on your back for 30 to 60 minutes, as it’s required for the procedure.

What happens during Gamma Knife surgery?

On the day of your procedure, the following steps prepare you for a Gamma Knife procedure:

IV: You’ll receive an IV in a vein in your arm. The IV delivers a contrast agent (a type of dye) that helps with imaging tests. The IV can also deliver a small amount of sedatives to help you relax if needed. General anesthesia might be an option for children (so they’ll be asleep).
Imaging tests: Your care team will perform imaging tests like a computed tomography (CT) and/or magnetic resonance imaging (MRI) scan. Imaging determines the exact size and location of the affected area of your brain where the procedure will be done. The scanning usually takes about 30 minutes.
Procedure planning: Your care team (a neurosurgeon, a radiation oncologist, medical physicist and other team members) plan your treatment on a computer. They’ll decide the area(s) to treat, the radiation dose and how to target the lesion for best results based on what they found on the imaging test. This can take up to an hour.

Does Gamma Knife surgery hurt?

No. You won’t feel any pain or discomfort during the procedure. The machine doesn’t produce any heat. You won’t hear any noise. A healthcare provider may give you sedatives to help you relax and stay still. Many people take a nap during the procedure.

How long does Gamma Knife surgery take?

Gamma Knife surgery itself takes between 30 minutes to two hours. It varies based on the size, shape and location of the affected area of your brain that needs treatment.

You should plan to spend several hours (up to 12) at the treatment center. Your care team will discuss the best timeframe for your situation before the date of your procedure.

What happens after Gamma Knife surgery?

After the procedure, you’ll feel a little groggy and drowsy from the relaxation medicine given when a frame is used. You should have someone drive you home from the procedure if a frame is necessary. You can go home the same day unless a healthcare provider recommends you stay overnight in the hospital for monitoring.

You should be able to get back to your regular activities like work and school the next day.

Risks / Benefits

What are the benefits of Gamma Knife surgery?

The benefits of Gamma Knife surgery include but aren’t limited to the following:

It doesn’t require incisions (cutting into your skin).
It safely reaches tumors or lesions deep within your brain that traditional surgery can’t reach.
The procedure can target multiple tumors and lesions at the same time.
It limits damage to surrounding tissue.
Recovery time is quick.

How successful is Gamma Knife surgery?

Gamma Knife surgery is a successful and effective procedure to treat small tumors and other brain lesions. One study reported that the tumor control rate was 95%. Tumor control refers to the destruction of tumor cells that affect their growth.

The success of the Gamma Knife procedure depends on the size, location, type of lesion and your general health at the time of the procedure, among other factors. Your care team will discuss their expectations and outlook for your situation before the procedure begins so you can make an informed decision about your health.

Depending on the reason for the procedure, you may or may not need additional Gamma Knife treatment or traditional surgery. You’ll have follow-up CT and/or MRI scans to check on treatment progress.

What are the risks or complications of Gamma Knife surgery?

While risks related to the procedure are typically low, risks and/or side effects of Gamma Knife surgery may include:

Nausea and vomiting.
Headache.
Feeling tired.
Bruising and skin discoloration at pin placement sites.
Numbness/tingling sensation on the scalp at the pin placement sites.
Hair loss (only if a tumor is close to the scalp).

I hope this helps.

Take care.

Well that’s a silly name then isn’t it? People have enough anxiety before operations then to worry about the name of the procedure itself. They should rename it to Gamma Caress Therapy or something like that.
