Trigeminal Neuralgia Treatment: CyberKnife vs. Gamma Knife

Trigeminal neuralgia is a painfully debilitating neuropathic disorder. Commonly referred to as TN, the condition is a disorder of the trigeminal, or fifth cranial, nerve that controls sensation in the face. TN patients experience episodes of intense, electroshock-like pain on either side of the face, in the forehead or along the jaw. TN is usually diagnosed based on a patient’s description of symptoms.

On demand Gamma-knife strategy can be safely combined with BRAF-inhibitors for the treatment of melanoma brain metastases

Annals of Oncology,   Clinical Article

Gaudy–Marqueste C, et al. – Both Gamma–Knife radiosurgery (GKRS) and BRAF–inhibitors (BRAF–I) have been shown to be useful in melanoma patients with brain metastases (BM), thus suggesting that it could be interesting to combine their respective advantages. Interrupting BRAF–I for stereotactic radiosurgery of BM seems useless, although it is still advised for other radiation therapies. The potential benefit of combining stereotactic radiosurgery and BRAF–I can be safely tested.

Gamma Knife Perfexion

Brain tumors treatment with GAMMA KNIFE PERFEXION 
Contrary to some other techniques used in radio surgery, Gama Knife is better because:
Its precision is unmatchable
Superb tech characteristics provide 0.3 mm precision
Great efficiency
Huge number of scientifically related articles about Gama Knife has been published.
Many centers use it.

Optimization of Gamma Knife Radiosurgery

  • Abstract.
  •  The Gamma Knife is a highly specialized treatment unit that pro-
  • vides an advanced stereotactic approach to the treatment of tumorsvascular
  • malformations, and pain disorders within the head. Inside a shielded treatment
  • unit, beams from 201 radioactive sources are focused so that they intersect at
  • the same location in space, resulting in a spherical region of high dose referred
  • to as a shot of radiationThe location and width of the shots can be ad-
  •  justed using focussing helmets. By properly combining a set of shots, larger
  • treatment volumes can be successfully treatewith the Gamma Knife.
  • The goal of this project is to automate the treatment planning process.
  • For each patient, an optimization seeks to produce a dose distribution that
  • conforms closely to the treatment volume. The variables in the optimization
  • can include the number of shots of radiation along with the size, the location,
  • and the weight assigned to each. Formulation of such problems using a variety
  • of mathematical programming models is described, and the solution of several
  • test and real-patient examples is demonstrated

Gamma knife radiosurgery for Cushing's disease and Nelson's syndrome


Marek J, et al. – Researchers from the Czech Republic present their 18–year experience in treating adrenocorticotropic hormone (ACTH) secreting adenomas (Cushing’s disease and Nelson’s syndrome) using the Leksell gamma knife (LGK) irradiation. They concluded that LGK radiation represents an effective and well–tolerated option for the treatment of patients with Cushing’s disease after unsuccessful surgery and may be a vialbe primary treatment in patients not suitable for, or who refuse surgery. In almost all patients with Nelson’s syndrome, this approach may impede tumorous growth and control the size of the adenoma.

I feel great though.One year ago and a few weeks previous i was in tremendous unbearable level 10+ pain.I believe God eased it off enough that i could leave the house and ride to Dallas to undergo a GK procedure.It took 6 to 8 weeks for the pain to go away... 

Edema and neurological deficit two years after Gamma knife

Dear all,

My mother had GK on one brain meta in April 2012. Everything was fine, and she had no problem at all. Than in November MRI showed slight signal enhancing. TH GK surgeon said it is normal and just to keep monitoring. In the mean time she developed severe headaches, high blood pressure and left arm and leg weakness. Everything culminated 10 days ago when she had complete paralysis of left arm and leg. She has strength but she cannot lean on them. They put her on steroids and it tokk them 6 days to start working. In the meantime she had one severe crisis with low pressure (64 44) which was terrible.

Can a Gamma Wave or beam, from the Gamma Knife be made as small as 0.1mm or smaller.?

If you made a pipe with a hole in the center around 0.1mm small enough for a Gamma wave, or beam to pass through it. 
The Cobalt source would be at the end of the pipe. 
Could a Gamma Knife wave, or beam pass through a hole this small. 
Thank you for your help with this question

Gamma Knife Procedure – Update and Pictures

Sorry this one has taken me so long to post.   I just get swept up in every day activities and never have time to sit down and write the blog as often as I would like.
I had hubby take a pic of me with my sexy Gamma Knife contraption on my head.  Warning, if you look closely enough you can see where they SCREWED the front piece to my skull!  Now many have been shocked to see that I was smiling in the picture.  They do give you an anti-anxiety  medication and then an injection of some other drug to make you a little loopy.  My advice.  Demand they give it to you more than 2 minutes BEFORE your procedure.  I should have had mine at least 30 minutes before but they didn’t have time.  So I was fully aware of what they were doing to my head because the meds didn’t kick in until after they finished.  And I could HEAR them screwing it through my flesh.  So I did what any girl would do….I cried like a baby and started to hyperventilate and then when the nurse told me to slow my breathing so I didn’t pass out, I held it in without even knowing I was doing that and she had to count with me to make sure I was breathing.

A New Study Reveals Longer Survival Outcomes For Patients With Malignant Brain Tumors

("Leading Edge" Gamma Knife Treatment, led by Christopher Duma, M.D., FACS and his team of researchers, offers hope to patients with Glioblastoma Multiforme)

NEWPORT BEACH, Calif.July 8, 2014 /PRNewswire/ -- A study on the effects of an aggressive and strategic treatment called "Leading Edge" radiosurgery offers hope to patients diagnosed with life-threatening brain cancer. The study identifies the pathways of invasion of malignant glioma cells and provides a map in which a treatment plan can be developed to prevent the spread of one of the most deadly forms of malignant tumor, Glioblastoma Multiforme (GBM). GBM currently has a median survival rate of about 16 months.

Cost savings will impact on treatment of cancer patients

I am relieved to say that following my latest series of scans, and after surviving some 34 brain tumours, it appears that no further treatment is presently necessary thanks to the Gamma Knife team in Sheffield. NHS England please note – Gamma Knife works.

Stereotactic radiosurgery for trigeminal neuralgia using the gamma knife

2.1 Indications

2.1.1Stereotactic radiosurgery with the gamma knife is used to treat trigeminal neuralgia. This is a condition characterised by sudden bursts (paroxysms) of facial pain. These bursts may be triggered by touch, talking, eating or brushing teeth. The pain occurs in the areas supplied by the trigeminal nerve: the cheeks, jaw, teeth, gums, lips and, less often, around the eyes or forehead. Trigeminal neuralgia is rare; the annual incidence is 4 per 100,000 population.
2.1.2Some people with mild symptoms recover without treatment. For most people, the paroxysmal bursts of severe pain continue indefinitely.
2.1.3The first-line treatment for trigeminal neuralgia is medication. Surgery is considered for people who experience severe pain despite medication, or who have adverse effects from medication.

    Gamma Knife Radiosurgery for Mesial Temporal Lobe Epilepsy.

    Many patients with mesial temporal lobe epilepsy continue to have seizures despite medical therapy. For these patients, one recourse is surgical resection of the mesial temporal lobe, with its attendant risks. Noninvasive treatment with Gamma Knife radiosurgery is under active investigation as a possible alternative to open surgery. Accumulated evidence from multiple studies shows radiosurgery to be comparable in outcomes to surgical resection. A definitive randomized, controlled ...
