Brain tumors are serious conditions that require highly precise treatment. This is due to the complexity of the brain, which controls many vital body functions such as movement, speech, and vision. Therefore, brain tumor surgery requires advanced technology to help doctors visualize brain structures in detail, ensuring the procedure can be performed safely and accurately.
Mandaya Royal Puri Hospital Jakarta is now equipped with 3D real-time neuronavigation technology, often referred to as “brain GPS.” This system allows neurosurgeons to accurately locate tumors and determine the safest surgical pathway. With this technology, the chances of optimal tumor removal increase while minimizing the risk of damage to healthy brain tissue.
This neuronavigation technology is utilized by Dr. dr. Mardjono Joy Tjahjadi, Sp.BS, Subsp. N-Vas, F. N-Onk, PhD, FICS, IFAANS, also known as Dr. Joy, a neurosurgeon experienced in handling complex neurological cases. In certain cases, including hard-to-reach tumors such as trigone meningioma, this technology significantly enhances surgical precision.

The Importance of 3D Neuronavigation in Brain Tumor Surgery
In modern neurosurgery, accuracy is a critical factor. Surgeons require precise guidance to identify the tumor location and determine the safest surgical approach. Neuronavigation technology addresses this need by providing a three-dimensional map of the brain that can be viewed in real time during surgery.
Through this system, doctors can clearly understand the relationship between the tumor and surrounding brain tissues. This enables more targeted tumor removal while preserving healthy brain structures.
Key benefits of brain GPS technology include:
- Accurate mapping of tumor location based on integrated MRI or CT scan data
- Assistance in determining the safest and most effective surgical pathway
- Real-time visualization of surgical instruments within the brain map
- Reduced risk of injury to critical brain areas such as those controlling movement, speech, and vision
- Clearer tumor boundaries, allowing for more complete tumor removal
This technology is especially valuable for tumors located deep within the brain or in difficult-to-access areas. With precise navigation, surgical success rates can improve while reducing the risk of complications.
How 3D Neuronavigation Works in Brain Tumor Surgery
The neuronavigation system operates through several integrated steps:
- MRI examination: The patient undergoes a brain MRI to obtain detailed images of brain structures and tumor location
- Data integration: MRI results are uploaded into the neuronavigation system to create a digital brain map
- Surgical planning: Neurosurgeons plan the procedure and determine the best approach using the system
- Patient alignment: The system is synchronized with the patient’s head position in the operating room
- Tumor marking: The tumor location is identified and marked as a surgical guide
- Detailed visualization: The system displays the brain, tumor, and blood vessels in color-coded images
- Safe pathway guidance: The technology helps determine the safest surgical route to minimize damage to healthy tissue
With this workflow, 3D brain mapping technology enhances surgical precision while improving patient safety during the procedure.
Patient Story: Successful Brain Tumor Surgery Outcome
One successful case at Mandaya Royal Puri Hospital involved Mr. GBD, a content creator known as Elder Storyteller. He underwent surgery to remove a 4×4 cm meningioma brain tumor with Dr. Joy.
His condition began with sudden seizures while having a meal with his family. After undergoing CT scan and MRI examinations, doctors discovered a tumor on the left side of his brain that was pressing on nerves and affecting his vision. The tumor was also suspected to be the cause of previous symptoms such as visual disturbances and occasional falls.
With the support of neuronavigation technology, approximately 99% of the tumor was successfully removed based on post-operative imaging results. His recovery process was also relatively fast. He did not require ICU care and was able to sit, stand, and walk within a few days after surgery.
This case demonstrates how the combination of medical expertise and advanced technology can significantly improve surgical outcomes and accelerate patient recovery.
