Acoustic Neuroma Gamma Knife Surgery: Risks & Benefits

Whether you already have your acoustic neuroma Gamma Knife surgery scheduled or are still exploring your treatment options, it is important to understand the risks and benefits of the procedure. Educating yourself is a great way to develop confidence in your upcoming treatment, leading to more in-depth conversations with your personal doctor and peace of mind throughout the process.

As you learn more about the risks and benefits of Gamma Knife radiosurgery, it is important to keep in mind that your personal doctor takes all of these factors into consideration before making any treatment recommendations. He or she will be the best person to discuss the details related to your unique case. However, learning more at a broad level can help you better understand these risks and benefits as they apply to you personally.

What is an Acoustic Neuroma?

Before discussing acoustic neuroma Gamma Knife surgery, it helps to have a general understanding of your condition. An acoustic neuroma is a type of benign brain tumor that develops from the vestibulocochlear nerve, the cranial nerve responsible for hearing and balance. Most patients only develop an acoustic neuroma on one side, although bilateral acoustic neuroma is possible, especially in patients with a rare genetic disease called Neurofibromatosis Type 2.

Though your acoustic neuroma is benign, it may still grow large enough to affect nearby structures, requiring treatment to prevent further damage and/or progression of symptoms. The treatment a doctor recommends might include monitoring, surgery or Gamma Knife radiosurgery, depending on the characteristics of the tumor and a patient’s personal health factors.

What is Gamma Knife Radiosurgery?

Though it sounds like a surgical procedure, Gamma Knife radiosurgery is actually a minimally invasive treatment that uses radiation to shrink your tumor. During the procedure, your doctor will use nearly 200 individual beams of low-dose radiation that treat your tumor at the same time, targeting an area as precise as a single human hair. This allows your doctor to treat only tumor cells, sparing healthy surrounding tissue.

Gamma Knife radiosurgery is an outpatient treatment. This means you do not have to stay overnight in the hospital. The procedure itself takes 15-75 minutes, depending on the size and location of your tumor. Many patients can be treated in just one session, though you may require up to five, again depending on the characteristics of your individual tumor.

Risks of Acoustic Neuroma Gamma Knife Surgery

You may be familiar with other forms of radiation therapy and the side effects patients may experience following treatment. However, because Gamma Knife radiosurgery is so precise, there is less damage to healthy cells than with other radiation treatment and fewer side effects. However, some patients will experience a headache and nausea immediately following treatment. These effects tend to be mild and can be managed by medication if required. Other side effects immediately following treatment can include:

  • Fatigue
  • Itching or swelling where the headframe attaches to the scalp
  • Redness or discomfort at the treatment site
  • Rarely, hair loss at the treatment site
