Neurosurgery Advancements: From Technical Innovation to Patient-Centered Outcomes-A Narrative Review

Over the past decades, neurosurgery has undergone a profound transformation driven by technological innovation and a paradigm shift toward patient-centered outcomes. Historically evaluated through mortality rates and extent of resection, modern neurosurgery increasingly prioritizes preservation of neurological function, cognitive integrity, and quality of life. Innovations such as intraoperative mapping, multimodal neuromonitoring, image-guided surgery, minimally invasive techniques, and enhanced recovery protocols have reshaped surgical decision-making. However, the true value of these advancements lies in their measurable impact on clinically meaningful outcomes. This narrative review examines how technical progress translates into functional, cognitive, and quality-of-life benefits, while critically discussing current limitations of evidence and future directions toward personalized, outcome-driven neurosurgery.
