Neurosurgeon

What it is

A neurosurgeon is a surgeon who specializes in operating on the brain and nervous system. For gliomas, the neurosurgeon performs procedures such as biopsies and tumor removal (resection), using advanced techniques to remove as much tumor as safely possible while preserving function.

Understanding Neurosurgeon

The neurosurgeon is central to the surgical aspects of glioma care. Their responsibilities include obtaining tissue for diagnosis (through biopsy or resection), removing the tumor when feasible (maximal safe resection), and managing surgery-related aspects (such as relieving fluid buildup with a shunt). To operate safely — especially near critical areas — neurosurgeons use tools such as neuronavigation, intraoperative mapping and monitoring, fluorescence guidance, and sometimes awake surgery or intraoperative MRI. The neurosurgeon assesses whether and how a tumor can be operated on, performs the operation, and manages the immediate postoperative period, working closely with the rest of the team. Some neurosurgeons subspecialize in brain tumors (neuro-oncological or "tumor" neurosurgery), bringing particular expertise. The neurosurgeon's skill and judgment significantly influence both the diagnosis and the extent of safe tumor removal. Understanding the neurosurgeon's role clarifies the specialist who performs glioma surgery.

Why it matters

Understanding the neurosurgeon's role helps patients and families know who performs glioma surgery — a specialist in brain operations who obtains the diagnosis and removes tumor safely, using advanced tools to preserve function.
