Neurosurgery is the specialty concerned with the surgical treatment of diseases of the nervous system composed of the brain, spinal cord and spinal column, as well as the nerves that travel through all parts of the body. Modern day neurosurgery, however, is very different from what has been seen earlier.
Among medical specialties, neurosurgery is, by far one of the most technically advanced. There is virtually no area of the brain where lesions cannot be approached with a high degree of safety and accuracy with modern techniques like image-guided surgery. The advent of techniques of minimally invasive surgery have contributed to a much shorter hospital stay and heightened patient comfort, while maximizing the efficacy of the procedure.
