Introduction

   The Neurosurgery Department is where diseases in the central and peripheral nervous systems, including the brain and spinal cord, are diagnosed and treated surgically. The nervous system is a very important organ that regulates the functions of the human body. As even minor damage to this system can cause fatal sequelae and permanent dysfunction due to its complex structure, various clinical experience, a high level of knowledge, and delicate skills are required for the accurate diagnosis and treatment of such diseases. Our department is divided into divisions in accordance with the type of disease and treatment method such as brain tumor, cerebrovascular diseases, spine, trauma, and stereotactic function to provide more precise medical care for neurological diseases.

   Apart from the clinic in each field, our department has special treatment centers such as the Gamma Knife Center, Epilepsy intensive Center, and Movement Disorder Center are in operation and strives to provide comprehensive treatments by closely working with the Neurology Department under the “Cerebral Nerve Center.” 
 In addition to our clinical services, we have independent basic laboratories for brain tumors, cerebrovascular diseases, spine, and stereotactic functions to investigate the pathophysiology of diseases and develop better treatment methods as a research-centered hospital. We publish more than 100 papers per year in international academic journals, playing a role also in clinical research.
