Successful brain aneurysm surgery
In September I had surgery for a brain aneurysm — it was performed by Professor Turker Kilic. A huge thank you to him and his entire team. They showed exceptional attention to their patients. I have now fully recovered. This is a reliable clinic that I will recommend to everyone.

High professionalism and humanity of the team
As a representative of a patient from Ukraine 🇺🇦, on my own behalf and on behalf of the patient, I would like to sincerely thank the Bahçeşehir Üniversite Hastanesi Medical Park Göztepe clinic (Istanbul) 🇹🇷 for the high level of professionalism and the incredible organization of work. We turned to this clinic after another clinic in Warsaw (Poland) had been unable to make a final decision on the diagnosis and treatment for a month. As a result, complex surgery was proposed, carrying a serious risk to the patient's life. The clinic's team impressed us with their coordination and efficiency: as early as the next day after our request we received a preliminary treatment offer, and two days later an examination date was scheduled. The clinic's management approached our situation with understanding — the patient was already in Europe, and returning to Ukraine in wartime was difficult and time-consuming. For that reason, the admission and all necessary examinations were arranged in the shortest possible time. From the moment we arrived in Istanbul, every step was organized impeccably: airport transfer, paperwork, doctor's examination, and the treatment itself. On 3 March, a patient diagnosed with a sixth cranial nerve schwannoma underwent the Gamma Knife procedure. We would like to express our heartfelt gratitude to the entire team of the Gamma Knife department and especially to neurosurgeon Professor Dr. Turker Kilic — for his high professionalism, care for the patient, support, and humanity. Special and very warm words of thanks go to the clinic's interpreter, Elmira Okuş. Her language skills, sincerity, willingness to help, constant support, and assistance with every issue were invaluable to us. After a long and difficult search for a solution, it was Bahçeşehir Üniversite Hastanesi Medical Park Göztepe that managed to organize everything quickly, clearly, and professionally. The patient successfully returned to Ukraine and resumed her professional activities. With great gratitude and confidence, we recommend this clinic to anyone looking for modern medicine, high professionalism, and genuine patient care. Special thanks to Professor Turker Kilic and the entire Gamma Knife department team. Thank you all for your work and attention ❤️

Appointment rescheduling and inconvenience
They called us and asked to reschedule the appointment from 11:50 to 9:30. When we explained that we were coming from out of town, they barely managed to set the appointment for 10:25. And now it is 11:20 and we are still waiting for that appointment. 🤷‍♂️ P.S.: The reason for the rescheduling was that Doctor Turker Kilic needed to leave after 11:00 — I assume because today a national holiday begins at noon. P.S. 2: When we suggested an online consultation (which would have been more convenient for them too), we were told that it would cost extra. It seems they only care about what is convenient for themselves.

A very bad treatment experience
STAY AWAY FROM THIS HOSPITAL IF YOU DO NOT WANT TO BE HUMILIATED FOR YOUR MONEY! On 12 September 2025 I had foraminal injections and radiofrequency ablation at Medical Park Göztepe. Everything was a disaster — from the moment we entered the hospital until we left. I was admitted for a day-stay and given a bed next to the toilet, in a space resembling a converted emergency department where patients were separated only by curtains. We waited in a room that smelled strongly of urine. When I was being taken to the operating room, I accidentally found out that Dr. Mehmetzeki Yıldız, who had examined me and said "I am performing the procedure," was on vacation abroad. I was not informed in advance, and I was not asked whether I would agree to a different doctor. After the procedure I was taken back to the same room with the smell of urine. They told me I had to follow a salt-free diet. The food they brought turned out to be very salty soup and a piece of bread! When I told the nurse the soup was too salty, she "brilliantly" replied: "I don't know, madam (that's how they speak to patients!), just don't add any more salt." A foreign assistant came over, whose Turkish was barely sufficient to express herself, and gave me a prescription. She was neither the doctor who performed the procedure nor the assistant who had been in the operating room — so I did not get any clear answers to my questions. I asked them to call another doctor who could give me real information, or at least someone who had been in the operating room during the procedure. They said "okay" and made us wait a whole hour, after which the same assistant returned! It looked like they were mocking us. The examination document and the surgical report listed the name of Professor Dr. Turker Kilic, who was not present either at the examination or in the operating room. The names of Dr. Mehmetzeki Yıldız, who had examined me, and Dr. Emre Ünal, who performed the procedure, were missing. In addition, I had complained of severe back pain and such severe lower-back stiffness that I could not walk, but the report stated that I had complained of pain in the left leg and that my pain, which has lasted more than fifteen years, had only started the day before. It was a medical report that had nothing to do with me — as if it were about another patient. There was no follow-up at all. We were not even called for a check-up. I contacted Mrs. Tugba, who had organized this procedure at the neurosurgery department. When I told her that the doctor had been changed without informing us, despite the professor saying "I will be operating," she lied to my face: "The professor's surgery ran long, so another professor took over." When I objected that we knew the professor was on vacation abroad, she became flustered. We paid fifty thousand liras and received treatment we would not have received even at a public hospital. To be honest, I no longer believe in the correctness of the procedures performed, nor that they were performed at all. They also did not give me any information about the pain that started in the shoulder blade after the procedure and spread to the back and leg — how the recovery process would proceed, how long it would take, or when it would begin.

Thanks to the team for their care and professionalism
Hello! About 20 days ago, at Medical Park Göztepe Hospital, I had complex surgery to remove a fibroid and an ovarian cyst — performed by gynecological surgeon Ahmet Mehmet Cambaz. Before the surgery I was also under medical supervision and was taking medication. Over the course of two months, I felt the meticulous, calm, and unfailing attention of our doctor. Not a single question or concern of mine was left unanswered. A huge thank-you to him. Also endless gratitude to his assistant, Mrs. Semiha, for her solution-oriented and very positive approach, to all the operating-room staff, and to the floor nurses. Special thanks to Mrs. Hatice from the radiology department — she has always been there to help me and my family. I would also like to wholeheartedly thank Mrs. Tuba — assistant to Professor Dr. Turker Kilic — for the warm attention and help she gave me. How wonderful it is that you exist! 🙏

Clinical experience: over 29 years

Turker Kilic — a Turkish neurosurgeon and one of the pioneers of Gamma Knife radiosurgery in Turkey. He was the first to apply this method for brain tumor treatment in the country — in 1997, after training at the Karolinska Institute in Sweden.

His main clinical focus areas are brain tumors and cerebrovascular diseases.

He works in two modalities: open microsurgery and Gamma Knife. The combination of these two methods makes it possible to choose the optimal approach for each individual patient, and sometimes to use them sequentially.

Kilic is the founder and the first dean of the Faculty of Medicine at Bahçeşehir University (BAU); he currently serves as dean of the Faculty of Medicine at Istinye University.

He is also the founder of the Turkey Brain Foundation and the Istanbul Institute of Neurological Sciences (2020).

He was elected to the European Academy of Sciences and Arts (2014) and to the World Academy of Art and Science (2021).

He has more than 200 scientific publications, more than 6,000 citations, and an h-index of 40. He has been invited to lecture at Harvard Medical School, Yale University, Johns Hopkins University, and Politecnico di Milano.

According to patient reviews from open sources, Kilic’s practice is traditionally in demand for diagnoses such as arteriovenous malformation, brain metastases, acoustic neuroma, meningioma, trigeminal neuralgia, pituitary adenoma, and cavernoma.

For a patient with a brain tumor or a cerebrovascular anomaly, this is a clear and strong choice: a doctor with proven experience in Gamma Knife radiosurgery and brain microsurgery since 1997, with a strong academic background and international recognition.

Turkey, Istanbul

Medical Park Göztepe Hospital Complex (BAU Medical Faculty Medical Park Göztepe), Istanbul.

The key advantage of this center is the combination of Gamma Knife radiosurgery and open microsurgery within a single team.

In radiosurgery centers around the world, Gamma Knife procedures are often performed only by radiation oncologists with no open-surgery practice; here, however, Gamma Knife procedures are performed by practicing neurosurgeons, which makes it possible to evaluate the tumor and make decisions from a surgical standpoint.

Gamma Knife Icon is one of the most modern radiosurgery devices, with positioning accuracy of about one-eighth of a millimeter. This is important for tumors located near vital brain structures.

The center treats international patients: it provides online consultations, accepts MRI scans before arrival, treatment usually takes a single session, and the patient may be discharged on the same day.

Used for brain tumors, pituitary adenomas, meningiomas, cavernomas, trigeminal neuralgia, metastases, arteriovenous malformations, and acoustic neuromas.
