Since its foundation on September 1, 1957, the Department of Neurosurgery has concentrated on the education, research and clinical works on neurosurgical disease. There are 28 medical doctors including 10 faculty members, 4 fellows, and 14 residents. The formal training curriculum consists of a 1year internship and 4year residency, and it focuses on promoting residents to independent specialists. In order to experience various fields, the fellows rotate in four fields: oncology, vascular neurosurgery, spinal and functional neurosurgery, and pediatric neurosurgery. A neurosurgery course for 3 credits is available for graduate students. At the neurovascular, brain tumor, epilepsy, and congenital malformation laboratories, multifarious basic and clinical research is performed. Image processing for stereotactic neurosurgery, dynamics of cerebrospinal fluid, and spinal cord injuries are also current research subjects of the Department. Available clinical fields are brain tumor, skull base lesions, neurovascular disease, interventional neurosurgery, vertebral and spinal cord disease, peripheral nerve disease, pediatric neurosurgical disease, stereotactic and functional disease, epilepsy, pain, rigidity, and spasticity. Recently, minimal invasive procedures such as gamma knife radiosurgery, endoscopic diagnosis and surgery, have been positively performed.
