Prof. Dr. Ilhan Elmacı was born in Niğde, a city located in the heart of Anatolia. He completed his high school education in Adana and graduated from Ankara University Medical School. His career began in 1987 at the Bakırköy Neurological Sciences Hospital, under the mentorship of Dr. Zeki Oral, where he completed his Neurosurgery residency by 1993. During this time, he also undertook groundbreaking micro neurosurgery training at Zurich University under the guidance of Professor M. Gazi Yaşargil.

From 1993 to 2003, Prof. Elmacı served as a teaching assistant and later assistant professor at Professor Necmettin Pamir’s Clinic, Marmara University Faculty of Medicine. He also enhanced his expertise in neurooncology and vascular neurosurgery at Johns Hopkins University, working with Professors Donlin M. Long and Daniele Rigamonti. In 2003, he was appointed Associate Professor of Neurosurgery.

Between 2004 and 2010, Prof. Elmacı served as Chief of Clinic at Göztepe Training and Research Hospital, where he led the clinic to become the first in Turkey accredited by the European Association of Neurosurgical Societies (EANS). During this period, he completed his endoscopic skull base surgery training at the University of Pittsburgh.

In 2010, Prof. Elmacı joined Acıbadem University Faculty of Medicine as a Professor of Neurosurgery and went on to establish the Neurosurgery Department at Medipol University Faculty of Medicine in 2012. He headed the Neurosurgery Department at Memorial Health Group Istanbul Hospitals from 2014 to 2018, and then worked with his team at Maslak Hospital, Acıbadem Health Group, until September 2021.

Since October 2021, he has been working with his team at his private clinic in Fulya and Ulus Hospital of Liv Health Group. Prof. Elmacı is the founding chairman of the Skull Base Society in Turkey and a member of the Executive Committee of the European Skull Base Society (ESBS). With more than 110 published scientific papers in international journals and over 250 congress presentations, he continues to shape the field of neurosurgery.

Since November 2023, he has been working with his team at Istanbul Florence Nightingale Hospital, focusing on cutting-edge areas of research and treatment, including brain and spinal tumors, pituitary adenomas, brain vascular diseases, back and neck pain, hydrocephalus, cerebellar herniation, syringomyelia, and trigeminal neuralgia. He also specializes in microsurgery, endoscopic surgery, and advanced techniques like neuromonitorization and neuronavigation to improve patient outcomes. His work is guided by ethical principles, always aiming to preserve patients' quality of life.

I am a graduate of the Medical University of Warsaw, a specialist neurosurgeon. I gained my professional experience in the Neurosurgery Clinic of the MSWiA Hospital in Warsaw, the Neurosurgery Clinic of the 2nd Faculty of Medicine of the Medical University of Warsaw, the Institute of Experimental and Clinical Medicine of the Polish Academy of Sciences.

I perform a wide range of neurosurgical operations, including spine surgery. I am also a long-time academic lecturer, co-author of several articles and congress presentations. I have participated in numerous national and international congresses and trainings, including in the field of endoscopic spine surgery.

I am a specialist in neurosurgery, a graduate of the Faculty of Medicine at the Medical University, a certified instructor of endoscopic spine surgery. I specialize in surgical treatment of brain and spine diseases, as well as in interventional pain treatment. I completed my specialization training in neurosurgery at the Department of Neurosurgery of the Medical University of Warsaw and at the Department of Neurosurgery of the CMKP in Warsaw. I have performed over 2500 surgeries on my own. I speak Polish, German, Russian and English.

I have special experience in the surgery of brain tumors - gliomas and tumors of the base of the skull. I also treat cervical, thoracic and lumbar discopathies with the use of classical (open) approach and with the use of endoscopic spinal surgery. I also deal with instrumental stabilization of the spine, insertion of artificial discs, apical-occipital decompression in Chiari syndrome, as well as microvascular decompression in vascular and nervous conflicts (trigeminal neuralgia, hemifacial spasm), My scope of interests also includes cranial base surgeries - interdisciplinary endoscopic surgeries with laryngological syndrome, hemangiomas and aneurysms of the brain (ruptured and unruptured, classic and endovascular surgeries - experience unique among neurosurgeons), spinal hemangiomas, endoscopic treatment of hydrocephalus and spinal cysts. In addition, I deal with interventional pain treatment by performing blockades of the spine, intervertebral joints, ganglia, peripheral nerves under X-ray or ultrasound control, thermolesion as well as implantation of spinal stimulators

The doctor studied at Ege University from 1997 to 2004, followed by a specialization in interventional radiology at Tepecik Training and Research Hospital from 2005 to 2010. He has since worked in a variety of hospitals as a diagnostic and interventional radiology specialist, and is a member of the Turkish Radiology Society, the Turkish Society of Interventional Radiology, the Turkish Medical Association and the Cardiovascular and Interventional Radiological Society.

Dr. Manfred Mühlbauer is a spinal neurosurgeon who graduated from Vienna Medical University. He has experience in minimally invasive and reconstructive neurosurgery of the spine and specializes in spinal neurosurgery, microsurgery of hernias of the intervertebral discs and vertebrostenosis, operations on HWS, BWS and LWS, and stabilization operations for spinal instability. He is a visiting professor at the Medical University of Vienna.

Professor Shimon Rohkind MD is an experienced neurosurgeon and pediatric neurosurgeon with over 35 years of practice. He is an expert in neurosurgery, spinal surgery, and peripheral nerve microsurgery, and he uses modern laser and bioengineering technologies to perform the most complex operations with minimal risk of complications. He is also involved in scientific research and is a member of the Israeli Society of Laser Neurotechnologies and the World Federation of Neurosurgical Societies.

Docent Stanisław Kwiek is an eminent specialist in neurosurgery.

Doctor Stanisław Kwiek is a graduate of the Silesian Medical Academy in Katowice. In 1995, he became a first degree specialist in neurosurgery and 3 years later completed his second degree specialisation in neurosurgery and neurotraumatology. In 1997, he was awarded a doctorate in medical sciences. A few years later, he defended his postdoctoral thesis entitled: ‘Determination of predictive factors determining the long-term outcome of patients with vestibular nerve casing operated on with retro-axial access: analyses and observations made on the basis of own surgical experience during operations performed with intraoperative multimodal monitoring of the patient's neurophysiological functions’. The paper was published in 2013 by the publishing house of the Silesian Medical University.

He acquired his professional experience working, among others, as an assistant professor at the Department of Neurosurgery of the Medical University of Katowice, with which he is still associated.

Dr Stanislaw Kwiek's professional interests include issues related to neurosurgery and neurotraumatology. He diagnoses and treats diseases of the nervous system, including discopathy.
