The neurosurgical outcome of a morbid process has been refocused from the concept of an alive individual to restoration of quality of life, in the present scenario. This has been possible due to rapid and explosive advances in all areas of neurosciences, especially Neuroradiology and more precise neurosurgical techniques and instrumentations including operating microscope.
