Brain tumors are serious medical conditions that require a very high level of precision in treatment, especially when the tumor is located in a difficult-to-reach area of the brain. This is the case with trigone meningioma, a rare type of brain tumor that grows inside the brain’s ventricular system. By utilizing advanced navigation technology such as a “brain GPS” and nerve monitoring systems during surgery, tumor removal procedures can be performed with greater precision and safety.
At Mandaya Royal Hospital Puri, this complex procedure was successfully performed by Dr. dr. Mardjono Joy Tjahjadi, Sp.BS, Subsp. N-Vas, F. N-Onk, PhD, FICS, IFAANS, widely known as Dr. Joy. During the procedure, Dr. Joy used neuronavigation technology (brain GPS) along with NERVIOM (Intraoperative Neuro Monitoring) to help remove the rare trigone meningioma tumor while preserving the patient’s critical nerve functions.

The Role of Advanced Brain GPS and NERVIOM Technologies in Trigone Meningioma Brain Tumor Surgery
Below is an explanation of how brain GPS neuronavigation and NERVIOM technology assisted Dr. Joy in removing a trigone meningioma brain tumor from a patient at Mandaya Royal Hospital Puri.
1. Brain GPS Technology (Neuronavigation)
In modern brain tumor surgery, neurosurgeons require extremely precise guidance to determine the exact location of the tumor and the safest surgical pathway. Neuronavigation technology, often referred to as a “brain GPS,” helps doctors map the brain’s structure in real time so that surgery can be performed more accurately.
The role of brain GPS technology in tumor surgery includes:
- Precisely mapping the tumor location based on MRI or CT scan results displayed in the navigation system during surgery
- Determining the safest surgical pathway so doctors can reach the tumor without damaging healthy brain tissue
- Assisting surgeons with orientation during the operation by displaying the position of surgical instruments in real time on a digital brain map
- Reducing the risk of damage to critical brain areas, such as centers responsible for movement, speech, or vision
- Increasing the success rate of tumor removal because surgeons can clearly identify tumor boundaries
This technology is especially important for tumors located deep within the brain and difficult to access, such as trigone meningioma.
2. NERVIOM (Intraoperative Neuro Monitoring)
In addition to accurately locating the tumor, doctors must also ensure that the patient’s vital nerve functions remain intact during surgery. For this purpose, NERVIOM (Intraoperative Neuro Monitoring) is used. This system monitors nerve activity directly in real time throughout the surgical procedure.
The role of NERVIOM technology in brain tumor surgery includes:
- Monitoring nerve function in real time during the operation
- Providing early warnings to surgeons if disruption occurs in certain nerve pathways
- Protecting essential body functions such as limb movement, speech ability, and sensory function
- Helping surgeons adjust surgical strategies if the system detects potential risks to the nerves
- Reducing the risk of neurological complications after surgery, such as paralysis or speech disorders
With the combination of brain GPS neuronavigation and NERVIOM technology, brain tumor surgery can be performed with a higher level of precision and safety. This increases the chances of successful tumor removal while maintaining optimal nerve function for the patient.
