What is neuronavigation? How is it treated?

The neuronavigation system, which is one of the most advanced techniques offered by medical technology in the field of surgery, is an application that helps to clearly determine the boundaries of the masses during operations and thus significantly increases the success of the surgery. Neuronavigation is not a stand-alone type of surgery, but an additional system to surgery that provides safety and comfort in brain surgeries and increases success. This system allows the location of the target to be determined and to reach this target with the least damage and the shortest way, just like the navigation applications used in mobile phones and automobiles. The system, which is only available in health institutions that carry out high-tech medical applications, is applied by surgical specialists trained in this technique. The use of neuronavigation technique in vitally important brain surgeries, where millimetric inaccuracies can cause great negativities, provides great convenience and success in medical terms.


What is neuronavigation and how is it done?

In operations performed using neuronavigation systems, all borders of the tumor and its relationship with sensitive tissues are clearly determined and the incision made to reach the mass is made from the right place. The margin of error is very low and USG (ultrasonography) can be used simultaneously with the surgical area. During the use of neuronavigation, the patient is taken with a millimeter thick MRI (magnetic resonance). Before the operation, the existing brain tomography and MR images of the patient are uploaded to the computer of the system. These images are fused with each other. The patient’s own brain mapping is done. Then, the device is introduced to the markers on the skin by means of an apparatus located close to the patient’s head and laser readers on the operating table. After these procedures, the location of the brain, the exact location of the lesion, the distance to important areas and the amount of tumor removal can be monitored on a screen with a special instrument held by the surgeon. The system works in coordination with the microscope and images are obtained simultaneously with the USG. The use of neuronavigation systems in surgical operations that require precision reduces the margin of error and increases the safety of the operation.


What are the benefits and risks of neuronavigation?

Brain surgeries are very risky and exact location of the tumor is very important. The use of neuronavigation in these surgeries allows both the prevention of damage to the healthy tissues while the brain tumor is removed, and the surgery to be performed through a smaller skin incision and the tumor to be accessed more quickly. The use of neuronavigation systems in surgical operations ensures that the margin of error during operations is minimized. However, whichever technique is used, there is always a small margin of error. Since the structure of the brain tissues and the functional map of the brain are different in every person, this ratio may differ from person to person. For this reason, it should be known that there is no certain guarantee for a surgery performed with a neuronavigation system, although the possible risks are much lower than other operations. In addition, as the tumor is removed during surgery, there is a minimal change in coordinates. In this case, the team, the surgeon’s knowledge of anatomy and the experience of working with the operating microscope come to the fore. Therefore, this technique should be applied by specialist surgeons who have received detailed training on the neuronavigation system and the use of the devices used in this system.

Brain surgeries are very serious operations that need to be well thought out and should be applied by expert hands while minimizing risks. If you also need to undergo neurosurgery, you can be examined in detail by applying to a healthcare facility where neuronavigation technique is used. As a result of the examinations and diagnostic tests to be performed by specialist physicians, you can reserve your day for the operation if you are eligible to be operated with this system.
