Neurosurgery as one of the surgical specialties and is inseparable from surgery in general; however, it became a special field of medical science at the turn of the 19th−20th centuries. Naturally, the general principles of modern surgery are also applied in our profession. It is clear that instruments, materials and hands should be sterile, the scalpel is sharp, and anesthesia is adequate. However, the specificity of the object, i.e., the nervous system, makes neurosurgery a very peculiar, to a certain extent, a unique surgical discipline.
The complexity of the structure of the nervous system, the high density of the location of functionally important elements, the direct proximity of the pathological focus to vital structures requires the highest precision of manipulation and enormous responsibility.
