Gamma Knife Radiosurgery
by Prof. Türker Kılıç, M.D.

Gamma Knife is a radio-surgical tool based on radiation therapy and used to treat tumors, vascular malformations and other disorders in the brain.

Neurosurgery

With reduced surgical complications, it is used to precisely target invasive brain tumors and disorders with precise and concentrated radiation beams that decrease damage risk of healthy brain tissue. The method is typically performed as an outpatient treatment where the patient doesn’t need to stay in the hospital.

The device is a like a semi-sphere surrounding the skull of the patient that has 192 beam sources spread on this semi-sphere. The tumor is precisely targeted from multiple angles that converge exactly on the it. Relatively weaker beams pass through healthy brain tissue from many different angles and unites on the targeted tissue to generate sufficient power to affect tumor. This enables tolerable radiation related effect on the health issue while handling tumor tissue with exactly the required amount of radiation.

Why Gamma Knife?

It is:

  • A safer alternative to standard brain surgery.
  • No incisions in the scalp needed.
  • No opening in the skull and the fragile tissues surrounding the brain needed.
  • No dissection into brain tissue needed.

Gamma Knife radio surgery is most commonly used to treat the following conditions:

  • Brain tumor. 
  • Arteriovenous malformation (AVM)
  • Trigeminal neuralgia
  • Acoustic neuroma
  • Pituitary tumors

Risks and Complications

Despite the fact that Gamma Knife procedure doesn’t involve surgical incisions and generally has fewer risks than traditional neurosurgery, there are potential complications associated with anesthesia, bleeding and infection. Possibility of each of these adverse effects is reduced with an experienced surgeon and a well-established hospital facility.

Known as one of the best Neurosurgeons in the world Prof. Türker Kılıç, focused his practice on Tumor Surgery, Vascular Neurosurgery, Glioma Surgery, Meningioma Surgery, Aneurysm, and AVM. He operated on more than 15.000 brain tumor cases in his career.

Since 1997 when Prof. Türker Kılıç had received his special training for Gamma Knife Radiosurgery in Karolinska Institute, Sweden where the treatment is invented, he has performed over 12.000 cases. Prof. Kılıç states the fact that Gamma Knife is a “technical advancement complementary to surgery” and the most common diagnosis where he uses this device is ‘metastasis’.

‘Especially in the last 5 to 6 years, Gamma Knife became the first treatment of choice in that field’

He emphasizes that Gamma Knife is not always an independent specific treatment modality but rather a complementary technical advancement in neurosurgery. In pituitary adenoma, sometimes it is used before micro or endoscopic surgery, sometimes used after surgery as complementary. Through this way of combined technique, risks and side effects are decreased and an increased success rate of the surgery is achieved.

“A good Gamma Knife radio surgeon is the one who is good at the microsurgical treatment of this specific condition as well.”

Prof. Türker Kılıç highlights the importance of Turkey as a hub for healthcare services because of two main reasons. The first is the quality of education in the field of medicine which historically proved to produce competent physicians. The second reason is the technological advancements that Turkey has considering in the last 15 years.

As is the Founding Dean of Turkey’s biggest private university Bahçeşehir University, Prof. Türker Kılıç tackles the debate over academic titles & performance, which a frequently asked question; Does a high h-index also show the high quality of surgical skill? He states even though academic performance does not always reflect good technical skills, it’s better to look first at highly qualified academic physicians to find physicians with superior skills. He holds an h-index of 34 and at the same time performed over 15.000 tumor surgery cases, that makes him a perfect example to prove academic and surgical quality go hand in hand.
