Guwahati, Jan 16: When we think of brain surgery, many people imagine a highly risky procedure where the chances of damaging healthy brain tissue are high. While surgery for brain tumors remains one of the most delicate operations in medicine, advances in technology are making it far safer and more precise. One such breakthrough is neuro-navigation, often compared to a GPS for the brain.
Neuro-navigation is a computer-assisted technology that allows surgeons to map and guide their way through the brain during surgery. Much like the GPS in a car helps drivers follow the safest and shortest route, neuro-navigation helps neurosurgeons plan the most accurate path to reach a brain tumor.
Dr. Hrishikesh Chakrabartty, Associate Director Neurosurgery, Max Super Specialty Hospital, Vaishali said
“Using MRI or CT imaging, neuro-navigation creates a detailed three-dimensional map of the patient’s brain, which is used to guide the surgeon in real time during surgery. This technology helps accurately identify the exact location of the tumor before any incision is made, enables selection of the safest surgical pathway with minimal disturbance to healthy brain tissue, and allows continuous tracking of surgical instruments to maintain precision throughout the procedure.”
By acting as a guide, neuro-navigation minimises guesswork. The surgeon can see where the tumor begins and ends, as well as nearby blood vessels and sensitive brain areas. This reduces the risk of complications such as speech difficulties, weakness, or vision loss after surgery. It also increases the chances of removing the tumor completely, which is crucial in preventing recurrence and improving long-term survival.
Dr. Hrishikesh further added
“Neuro-navigation greatly reduces the risk of injury to healthy brain tissue, making brain tumor surgery safer and more controlled. By enhancing surgical precision, it leads to shorter operation times, reduced blood loss, quicker recovery, and better preservation of neurological function, resulting in improved overall outcomes for patients. Neuro-navigation is most useful for patients with tumors located deep within the brain or close to areas that control important functions. Not all cases require it, but for many patients, it provides a safer option and greater confidence in treatment.”
Neuro-navigation is transforming neurosurgery by acting like a GPS for the brain. It allows surgeons to plan their route, avoid critical structures, and reach the tumor with remarkable accuracy. For patients, this translates into safer surgeries and a better chance of recovery without loss of vital brain function.
