[New surgical techniques for brain tumors]

During the past years, the development of new technologies and techniques has been applied to brain tumor surgery, leading to decreased surgical morbidity and increased efficiency. These techniques can be used to reduce the invasiveness of the surgical approach (endoscopy, neuronavigation, robotics), to improve guidance (stereotaxy, neuronavigation), to better identify the tumor limits (neuronavigation, metabolic imaging, intra-operative MRI) or the functional areas (functional imaging, electrophysiological functional mapping) to optimize resection and to respect eloquent areas. This article reviews these techniques, focusing on their respective principles, practical utility, impact and limits.
