Brain tumor removal surgery is a medical procedure that requires an exceptionally high level of precision and accuracy. The brain plays a vital role in regulating essential bodily functions, making even the smallest surgical error potentially lead to serious complications, long-term neurological disorders, or life-threatening conditions. Therefore, brain tumor surgery must be performed with meticulous planning and supported by high-precision medical technology.
As part of its commitment to delivering high-standard neurosurgical care, the Mandaya Brain Center at Mandaya Royal Hospital Puri has introduced Hyper-Realistic 3D Brainlab Neuronavigation technology. This advanced system plays a crucial role in enhancing the safety and accuracy of brain tumor surgery, while also enabling neurosurgeons to work in a more controlled, targeted, and optimal manner throughout each procedure.

A Closer Look at 3D Neuronavigation Technology at Mandaya Royal Hospital Puri
The neuronavigation technology used at the Mandaya Brain Center is Curve Navigation Brainlab, an advanced brain navigation system that allows neurosurgeons to visualize the patient’s brain structures in highly detailed and accurate three-dimensional (3D) images during surgery.
This system functions like a GPS for the brain, guiding surgeons precisely and safely to the tumor location or targeted area. Data obtained from the patient’s CT scan or MRI is processed into a hyper-realistic 3D brain model that can be monitored in real time throughout the surgical procedure.
With this technology, the position of surgical instruments can be directly visualized on the monitor, allowing every movement to be adjusted according to the patient’s actual brain anatomy. This approach helps minimize the risk of misdirection, protects healthy brain tissue, and enhances both safety and precision during brain tumor removal surgery.
Advantages of 3D Neuronavigation Technology at the Mandaya Brain Center
Below are some of the key advantages of the Hyper-Realistic 3D Brainlab Neuronavigation technology used at the Mandaya Brain Center:
- Higher precision in brain tumor surgery: Helps surgeons accurately determine the tumor location, allowing for more targeted and controlled removal.
- Protection of healthy brain tissue: Detailed 3D visual guidance enables surgeons to avoid critical brain areas responsible for movement, speech, and consciousness.
- Reduced risk of surgical errors: The neuronavigation system works like a brain GPS, keeping surgeons on a safe and precise pathway during the procedure.
- Real-time hyper-realistic 3D visualization: Surgical instrument positions can be monitored instantly, allowing each surgical step to be adjusted according to the patient’s current brain condition.
- Supports safer neurosurgical procedures: High accuracy helps reduce the risk of complications, bleeding, and unintended nerve injury.
- More optimal tumor removal: Enables maximum tumor resection while preserving the patient’s brain function.
