Minimally Invasive Neurosurgery: Principles and Practice

Minimally invasive neurosurgery (MIN) represents a significant advancement in contemporary neurosurgical practice, aiming to achieve optimal clinical outcomes while minimizing physical, psychological, and economic burdens associated with conventional surgical approaches. Traditional neurosurgical techniques often require large incisions, extensive tissue manipulation, and prolonged recovery periods. In contrast, MIN emphasizes precision, tissue preservation, and reduced surgical trauma through the use of mini-incisions, targeted surgical corridors, and advanced instrumentation. The evolution of high-resolution imaging, endoscopic techniques, neuronavigation systems, robotic assistance, and intraoperative monitoring has substantially enhanced surgical accuracy and safety. Core principles of MIN include enhanced visualization, integration of advanced technologies, and interdisciplinary collaboration, all of which contribute to improved patient outcomes. A wide range of minimally invasive techniques—such as neuroendoscopic procedures, keyhole craniotomies, stereotactic interventions, and minimally invasive spinal surgery—have expanded the therapeutic options for complex cranial and spinal pathologies. Despite its advantages, MIN presents challenges including a steep learning curve, high technological costs, limited accessibility in resource-constrained settings, and the need for careful patient selection. Future directions in MIN are closely linked to innovations in artificial intelligence, augmented and virtual reality, nanotechnology, and regenerative medicine, which hold promise for further improving precision, safety, and postoperative recovery. Overall, minimally invasive neurosurgery continues to redefine neurosurgical care by aligning technological innovation with patient-centered outcomes.
