The Asianinfluenced part of the country is known as Anatolia, and the smaller, European-influenced portion is called Thrace. Evidence of neurosurgery practice in Anatolia dates back to the Neolithic Age.1 The majority of historical evidence as to surgical intervention and trepanation in Turkey, however, dates back to the Iron and Bronze ages1 (Figure 1). The civilizations of Anatolia were followers of each other, with each civilization connected to its predecessor. These civilizations include the Hittites (2500-1200 BC); Ionians (1050-300 BC); Urartus (900-600 BC); Phrygians, Lydians, Carians, and Lycians (750-300 BC); Hellenistic and Roman civilizations (333 BC-AD 395); Byzantines (AD 3301453); Seljuks (AD 1071-1300); Ottomans (AD 1299-1923); and contemporary Turkish Republic.2 Turkey is the birthplace of many famous ancient physicians such as Galen of Pergamum (201-131 BC), Aretaeus of Cappadocia (81-138 BC), and Şerafeddin Sabuncuo glu of Amasya (1385-1468), who each had a long history of medical practice according to classic GrecoRoman and Islamic medical doctrines. Modern medical and surgical practice was ushered into Turkey during the first half of 19th century. In what follows, the development of modern neurosurgery in Turkey and the current status of neurosurgery and practice in the country are discussed. DEVELOPMENT OF MODERN MEDICAL EDUCATION IN TURKEY During the rise (1299-1453) and expansion (1453-1556) periods of the Ottoman Empire, medicine was practiced according to classic Greco-Roman and Islamic doctrines. The first university (Istanbul University) within the empire was established in the year 1453 after the conquest of Istanbul by Sultan Mehmet II the Conqueror, and Fatih the Conqueror’s Mosque Complex (1470) later became a location for medical education and patient care for .350 years. Similarly, the Süleymaniye Mosque Com- 56 | VOLUME 63 | NUMBER 1 | AUGUST 2016 plex, founded by Sultan Süleyman I (the Magnificent) in 1555, included a hospital for patient care and medical education and served people until the early 2000s.3 Other hospital complexes included Bursa (1339), Edirne (1488), and Manisa (1539).4 However, as a result of changes in the Western world such as the Renaissance, Reformation, and conquest of the new world, the Ottoman Empire was unable to keep up in terms of medical knowledge, and the empire entered a long period of stagnation from 1566 to 1827. During this period, the empire suffered a major reduction in its military, political, economic, and scientific powers. At the beginning of the 19th century, attempts were made to modernize the army to compete with the Western world. As a result, the first military schools were opened, which included medical schools and military hospitals. The first modern military medical school, Tersane Tıp Mektebi (Naval Medicine School), was established by Sultan Selim III in 1805 as part of an attempt to modernize the traditional army (Janissary System).5 However, this attempt failed; Sultan Selim III was dethroned, imprisoned, and later killed in a revolt led by the Janissaries in 1808; and the medical school was closed. Later, Sultan Mahmud II was able to establish reforms and to replace the traditional army (the Janissaries) with a modern, Westernlike army. As a result, the first medical schools Tıbhane-i Amire (the School of Medicine) and Cerrahhane-i Amire (the School of Surgeons) were founded during Mahmud II’s reign in 1827.1 These 2 schools were joined in 1839, representing the core of what is now the Istanbul Medical Faculty of Istanbul University.1 The language of education was French, with Dr Charles Ambrois Bernard holding the first position of dean of the Medical Faculty.6 The faculty had a medical journal titled Vakayı I_ lmiye, and first graduates of the school exited in 1843.6 The Gülhane Military Medical Academy was founded in 1898 and included Drs Robert Rieder and Georg Dycke, chairmen from www.neurosurgery-online.com Copyright © Congress of Neurological Surgeons.

In 1908, these 2 medical schools were united as a part of the university Darülfünun-ı Osmani.”6 During the 1909-1910 academic year, a Turkish surgeon, Cemil Paşa (Topuzlu), became the chairman of the educational board of the faculty (Figure 2). The medical faculty had undertaken an Anglo-Saxon–type education similar to its Western counterparts, which consisted of 5 years of theoretical, practical, and clinical education and a 1-year internship (Figure 3).6 With the foundation of the modern Turkish Republic by Mustafa Kemal Atatürk in October of 1923, the country entered a whole new era. Following Atatürk’s mantra that “the most real guidance in the life is science,” the principles of education in the country were completely transformed. Although centers of Western-type education, as explained above, were available for citizens during the Ottoman Reign, public education throughout the majority of the country remained traditional. However, with the reforms of the Turkish Republic, all levels of public education were made to include methodologies that were more modern. For FIGURE 2. Cemil Topuzlu was a very important figure in the history of both surgery and neurosurgery in Turkey. He is most likely the first Turkish physician to present a case at an international conference (International Congress of French Neurosurgical Society, Lyon, 1894) in the field of neurosciences.

Hospital buildings used for medicine faculties in the late Ottoman period were derived from buildings designed for other purposes. The building of the Faculty of Medicine, then called Mekteb-i Tıbbiye-i Şahane, was built in 1903 and designed by Alexandre Vallaury and Raimondo D’Aronco, famous contemporary architects of the period, as an 80 000-m2 hospital complex. Today, it serves as the campus of Marmara University. example, the first female students graduated from medical school in 1927. The modern concept of a university in Turkey was established in August 1933, along with the countrywide drive for university reform.6 With the help of Jewish-German scientists such as Drs Erich Frank and Rudolph Nissen, who fled their homeland because of the rise of Nazism, the Medical Faculty of Istanbul University grew to become an important educational center. To this day, the center maintains its reputation via the contributions of many Turkish scientists, who are motivated by the philosophy of the republic. Aziz Sancar, who won a Nobel Prize in 2015 for chemistry, graduated from Istanbul University’s Medical Faculty in 1969. Today, there are .84 faculties of medicine in the Turkish Republic, making the country one of the most important in the world in terms of research productivity in this area.7 HISTORY OF NEUROSURGERY IN TURKEY In the second half of the 19th century, many Turkish physicians were sent abroad for medical and surgical training. Among them, Cemil Paşa (Topuzlu), who completed his surgical training in France, became a pioneer in the field of surgery.1,8,9 In addition to being considered the founder of modern surgery in Turkey, Topuzlu also played an important role in the development of neurosurgery in the country, performing various neurosurgical procedures for cranial traumas, peripheral nerve injuries, Pott disease, spinal injuries, and cerebral infections,1,9 Indeed, he is most likely the first Turkish physician to present a case at an international conference (the International Congress of French Neurosurgical Society, Lyon, 1894) in the field of neuroscience.9 Topuzlu’s case concerned a patient who presented with jacksonian epilepsy caused by an open compression fracture on 58 | VOLUME 63 | NUMBER 1 | AUGUST 2016 the motor cortex complicated by a brain abscess. The abscess was successfully treated via drainage.10 The case is notable in that it was presented only a few years after McEwen’s first report of brain abscess drainage. Neurosurgery has a relatively short history compared with other medical and surgical disciplines in Turkey. During the late Ottoman Period, much like Cemil Topuzlu, many general or ear-nose-throat surgeons performed neurosurgery. Such surgeons included Drs Alexander Kamburoglu (?-1913), Garabe Yahoub (1865-1936), Julius Wieting (1868-1922), Kerim Sebat (18701942), Orhan Abdi (1878-1948), Mim Kemal Öke (18841955), and Murat Cankat (1886-1963).1 Among these, Dr Öke, who was chief of the Gulhane Military Medical Academy and was later known as Atatürk’s personal doctor, wrote the first Turkish neurosurgical textbook, Dimag ve Cümcüme Afetleri ve Tedavileri (Disorders of the Brain and the Skull and Their Treatment), in 1924.11 Dr Mazhar Osman Uzman (1884-1955), who finished his training in Germany with Dr Emil Kraepelin, is considered the founder of modern psychiatry in Turkey. Between 1916 and 1918, Uzman published the first Turkish neuroscience journal, Emraz Akliye ve Asabiye Müsamereleri.12 Furthermore, he was a mentor to many young medical students and surgeons, encouraging them to train in the field of neurosurgery. Indeed, he played a crucial role in the establishment of neurosurgery as an independent discipline in Turkey.13 Under his influence, Dr Abdülkadir Cahit Tuner (1892-1980), originally a neuropsychiatrist, became the first physician in Turkey with a Neurosurgical Fellowship Certificate after working with Dr Otfrid Förster in Breslau, Germany, for a year.1,8,9 On his return, Tuner established the first neurosurgery department in Turkey at the Zeynep Kamil Hospital, where he performed craniotomies for brain tumors, laminectomies for spinal tumors, and percutaneous treatment for trigeminal neuralgia from 1923 to 1927.1,8 After 4 www.neurosurgery-online.com Copyright © Congress of Neurological Surgeons. Unauthorized reproduction of this article is prohibited HISTORY OF NEUROSURGERY IN TURKEY years of efficient work, however, he retired from his job as a result of a conflict with his mentor, Dr Uzman, which resulted in the delay of the development of neurosurgery in Turkey. Dr Hami Dilek (1892-1980), also originally a general surgeon, went to France in the late 1930s for neurosurgical training under Dr Uzman. He worked with Drs Clovis Vincent and Thierry de Martel, returning to Turkey after finishing his education in 1936.1,14 After his return, he opened an independent clinic as a division of the General Surgery Department at Bakırköy Hospital for Mental and Nervous System Disorders in 1947, which was the first neurosurgery clinic in Turkey.14 However, Dilek sought a neurosurgical center for both patient referrals and neurosurgical training. In 1949, he was able to achieve his goal in founding an independent clinic with 20 beds in Haydarpaşa Numune Hospital. The Ministry of Health soon accepted neurosurgery as an independent specialization, and Dilek’s clinic at Haydarpaşa Numune Hospital became the first neurosurgery department with a neurosurgical resident training program, for which he was appointed chairman.14 Along with Dr Dilek, Drs Cemil Şerif Baydur, Mustafa Sakarya, and Cafer Tayyar Kankat went abroad for neurosurgical training in the 1930s. Much as Dr Dilek did, Drs Baydur and Kankat went to France and worked with Drs Vincent and de Martel. Dr Baydur published a Turkish neurosurgical textbook called Nöroşirürji Bahisleri,15 and although Dr Kankat privately practiced neurosurgery instead of working in a university or government hospital, his contribution to Turkish neurosurgery came in the establishment of one of the earliest international neurosurgery journals, Modern Cerrahi ve Nöroşirürji Mecmuası (Journal of Modern Surgery and Neurosurgery), which ran from 1936 to 1947 (Figure 4).16 Dr Sakarya went to the United States and became a fellow of the legendary Dr Walter E. Dandy.17 The development of neurosurgery in Turkey as an independent specialization in the universities began in the 1950s. Dr Bülent Tarcan (1914-1991), originally a general surgeon, traveled to the United Kingdom in 1950 to train in the field of neurosurgery and to work with Dr Northfield.1,14 A versatile and sophisticated personality, Dr Tarcan was also very well known as a pioneer in the field of Western classical music in Turkey.18 Tarcan established the first neurosurgery clinic in a university hospital as a division of the General Surgery Department of Istanbul University, Istanbul Medical Faculty in 1952 on his return from the United Kingdom. This clinic would go on to become an independent department in 1968.19 Along with his neurosurgical achievements, he was a composer of various Western works of classical music, including piano suites, concertantes, chamber FIGURE 4. Dr Cafer Tayyar Kankat’s contribution to Turkish neurosurgery was to publish one of the first international neurosurgery journals, Modern Cerrahi ve Nöroşirürji Mecmuası (Journal of Modern Surgery and Neurosurgery), from 1936 to 1947.

After his retirement from the Istanbul University as a neurosurgery professor, he served as a professor of classical music composition at the State Conservatory of Mimar Sinan Fine Arts University (Figure 5).18 His versatile personality helped to shape and influence the professional and personal lives of his fellows, residents, and students and continues to influence the spirit of his department to this day. Dr Feyyaz Berkay (1915-1993), yet another Turkish general surgeon, completed his neurosurgical training with Dr Roland M. Klemme in the United States at St. Louis University between 1946 and 1951.1 He was the first Turkish neurosurgeon certified by the American Board of Neurosurgery,20 as well as the founder and first chairman of the Neurosurgery Department of the Cerrahpaşa Medical Faculty. Dr Berkay also played an important role in the establishment of the Turkish Neurosurgical Society (TNS) and the organization of the first national congress in 1971. Dr Hüsamettin Gökay, an American board– certified neurosurgeon, finished his residency under the supervision of Dr Paul C. Bucy in Chicago in 1954. He FIGURE 5. Dr Bülent Tarcan is the founder of the neurosurgery clinic at Istanbul University, which is the first neurosurgery clinic in a university hospital in Turkey. He is also one of Turkey’s famous classical music composers. His biography, written by Evin I_ lyasog lu, discusses his passion for both neurosurgery and classical music. 60 | VOLUME 63 | NUMBER 1 | AUGUST 2016 worked as an attending neurosurgeon in Chicago for another year before coming back to Turkey in 1955 to work in the Neurosurgery Department of Bakırköy Hospital for Mental and Nervous System Disorders and later in the Neurosurgery Department of Istanbul University’s medical faculty. Along with Dr Hamit Ziya Gökalp, Gökay is one of the oldest active members of the TNS, representing an excellent role model for young neurosurgeons in terms of professional discipline and dedication. Lastly, Dr Aysima Altınok finished her residency in the Neurosurgery Department of Haydarpaşa Numune Hospital under the supervision of Dr Dilek14 and became the first female neurosurgeon in Turkey in 1959. She is one of the earliest female neurosurgeons worldwide. Later in her career, she became chief of the Department of Neurosurgery at Bakırköy Hospital for Mental and Nervous System Disorders in 1968. She is still an active member of the TNS. After these developments in Istanbul, new neurosurgery departments started to develop in the relatively young universities of Turkey, beginning in Ankara, the capital and second biggest city, in the late 1950s. The Gulhane Military Medical Academy was the first center to have an independent neurosurgery clinic in Ankara. After finishing his residency abroad, Dr Zinnur Rollas became the chairman of the clinic in 1957,21 and in 1959, Dr Hamit Ziya Gökalp became the first resident of the clinic. However, because of the lack of a certain residency program, Dr Gökalp was sent to the United States for residency, and on his return, practical residency training began.22 Dr Vahdettin Türkmen, who finished his residency under the guidance of Dr Francis Grant at the Philadelphia Medical Center at the University of Pennsylvania, established the Neurosurgery Department of Hacettepe University’s Medical Faculty. However, just a year later, he left Turkey.1 Nurhan Avman (1928-1988), a former resident of Dr James Poppen at the Lahey Clinic in Boston and Dr Ernest Sachs, Jr at Dartmouth College School of Medicine, became the chairman of this department (Figure 6).1 In 1965, he left Hacettepe University and established the neurosurgery department of Ankara University. Neurosurgery departments were founded in Izmir at Ege University by Dr Erdem Tunçbay (1930-2010) in 1967 and in Adana at Çukurova University in 1972, which were then followed by the establishment of other departments countrywide.1 Dr Gazi Yaşargil also deserves mention as a figure who offered microneurosurgical training to many Turkish neurosurgeons from various clinics in his department in Zurich, which helped to develop Turkish neurosurgery in relation to the latest advances and technical standards. Including state and private universities, government training, and research hospitals, there are 83 neurosurgery training programs in Turkey today, with approximately 150 residents in training nationwide. There are currently .1500 neurosurgeons in Turkey. At present, a neurosurgical education lasts 5 years in Turkey, including 7 months of rotations. In terms of neurosurgical technologies and surgical techniques, Turkey is up to date with the developed countries of the world, and concerning research productivity, the country’s contribution to neurosurgical www.neurosurgery-online.com Copyright © Congress of Neurological Surgeons.

In 1985, the TNS was founded in Ankara by 9 neurosurgeons, with Dr Nurhan Avman selected as its first president. Subsequent presidents included Drs Aykut Erbengi, Özdemir Gürçay, Tunçalp Özgen, Yücel Kanpolat, Osman Ekin Özcan, Ertekin Arasıl, Yamaç Taşkın, M. Nur Altınörs, M. Kemali Baykaner, Kaya Aksoy, M. CLINICAL NEUROSURGERY Necmettin Pamir, Nurcan Özdemir, Ö. Selçuk Palaoglu, Mehmet Zileli, Ethem Beşkonaklı, Murat Bavbek, Ugur Türe, and Zeki Şekerci. There were 1400 members of the TNS as of 2015. The society mainly provides support to young neurosurgeons in terms of research and clinical education abroad, funds scientific projects, informs the public of and raises social awareness about issues of public health related to neurosurgery, and defends the professional rights of its members. In 2015, the TNS gave a total of 15 scholarships, each related to neurosurgical education abroad. The TNS also offers prizes for scientific research. In the current year, the prizewinners are as follows: Hamit Ziya Gökalp, Young Neurosurgeon Prize; Nurcan Özdamar, Best Scientific Research Prize; Erdem Tunçbay, Neurosurgery Board Examination Success Prize; Aysima Altınok, Best Neurosurgery Thesis Prize and TNS Best Scientific Research Prize; and Mahir Tevruz, Scientific Research Prize. The TNS has organized its annual congress in April at the time of the Neurosurgery Nursing Congress for the past 11 years. In 2016, both the 30th Annual Congress and 12th Neurosurgery Nursing Congress will be held. These congresses create environments for the scientific and social interaction of our members and residents in training. In addition to the annual meeting, there are monthly symposia organized by the TNS in major cities throughout Turkey such as Istanbul, Izmir, Ankara, Malatya, and Konya. Six different subspecialization groups exist for the training and education of TNS members, including Stereotactic and Functional Neurosurgery, Pediatric Neurosurgery, Neurovascular Surgery, Neuro-oncological Surgery, Spinal and Peripheral Nerves, and Surgical Neuroanatomy work groups, each of which organizes at least 1 annual symposium in addition to many local meetings and courses. Besides its scientific organizations, the TNS has established various committees and boards related to public relations, professional issues, social responsibility projects, and the provision of consultancy for different governmental agencies. The TNS has 2 scientific peer-review journals, both of which have been in continuous publication since 1989: a Turkish Journal called Türk Nöroşirürji Dergisi and the international journal Turkish Neurosurgery, which is currently indexed in Science Citation Index Expanded, Index Medicus, Medline, PubMed, and Scopus. The journal has an impact factor of 0.576, with a 5year impact factor of 0.702 according to the ISI Web of Knowledge, Journal Citation Report in 2014 (Figure 7). The first editor of this bimonthly journal was Dr Tunçalp Özgen, and its first editorial board included Drs Yücel Kanpolat, M. Nur Altınörs, M. Nuri Arda, and Kemali Baykaner. Dr Hakan Caner’s name should be mentioned also because of his enormous efforts and those of his editorial board during the registration of the journal in the Science Citation Index Expanded in 2008. Thanks to these efforts, the journal became more internationally known each year, with only 115 of 254 of the ahead-of-print articles now coming from Turkey. Submissions to the journal are of a great variety from all around the world, from the United States to Iran, Germany to Pakistan, VOLUME 63 | NUMBER 1 | AUGUST 2016 | 61 Copyright © Congress of Neurological Surgeons. Unauthorized reproduction of this article is prohibited KıRıs‚ AND AKÇAKAYA and South Korea to the Ivory Coast. From 2007 to 2013, 714 articles were published and 1154 articles were rejected. An online system has been used for submissions since 2006. Besides scientific journals, the TNS publishes a bulletin each year to inform members of various activities and events, with a printed edition of the bulletin also sent to members. In addition to the journals, the TNS has published several textbooks on different aspects of neurosurgery. The TNS has organized Basic Neurosurgery Courses since 2000 to provide a standard knowledge of neurosurgery for residents and young neurosurgeons. The education program and its duration are very similar to those of the European Association of Neurosurgical Societies (EANS) training courses. A cycle can be finished in 4 years, with 3- to 4-day courses taking place on different aspects of neurosurgery. In 2011, the TNS decided to organize an International Basic Neurosurgery Course based on other national courses. International Basic Neurosurgery Courses aim to function similarly to the EANS training courses and provide a standardized education program for neurosurgeons of different countries, with a particular focus on developing countries. Today, the course is a true success story for the TNS, with an increasing number of participants each year and with participants from .70 countries in 2016. The TNS is a member of EANS and the World Federation of Neurosurgical Societies. The TNS organizes not only courses and national congresses but also international meetings such as the Ninth International Cerebral Vasospasm Meeting, the Sixth Black Sea Neurosurgical Congress, the First Middle East Neurosurgical Symposia, the Asian-Anatolian Friendship Meeting, the Ninth Asian Congress of Neurological Surgeons, and joint meetings with other neurosurgical societies such as the First Korean-Turkish Neurosurgeons Joint Meeting in 2008 and the First GermanTurkish Neurosurgical Societies Joint Meeting in 2014. The TNS also signed an agreement with Congress of Neurological Surgeons, with the first joint meeting in April 2015 in Turkey, followed by another in September of the same year in New Orleans. Istanbul was chosen as the site of the 16th World Congress of Neurosurgery, and the World Federation of Neurosurgical Societies 2017 Congress in Istanbul will represent one of the most prestigious and important gatherings held by the TNS. Here, we have offered a brief summary of the history and current status of neurosurgery in Turkey, with a special emphasis on the TNS.
