Why Is Image Guided Surgery Performed?

IGS or neuronavigation, supports minimally invasive procedures, improves patient outcome and preserves neurological function. This, in return, reduces the length of hospitalization, increase patient flow and reduces the risk of revision surgeries. These are all factors where neuronavigation contributes to the reduction of overall hospital cost.

Image-guided surgery (IGS) is used to plan and perform surgery minimally invasive, such as a brain tumor removal or a brain biopsy. During a neuronavigation procedure, instrument movement inside the brain can be tracked on the monitor with millimeter accuracy, helping to avoid surrounding healthy tissue and critical areas as much as possible. Countless surgeons have commented and research shows many benefits to IGS:

  • Supports minimally invasive approach1
  • Pre-operative planning can help increase surgical confidence1
  • May improve patient outcomes, especially for certain tumors like gliomas1
  • Improves visualization of the operative field to help avoid critical brain structures1 
  • Pre-operative planning may help preserve important brain function1
  • Has been shown to improve surgical outcomes for complex surgeries1
  • May decrease the risk of surgical errors
  • May reduce operating, hospitalization and recovery time

The real-time display of instrument location, orientation and relationship to nearby structures in the brain has been demonstrated to enhance the confidence of surgeons and their perception of safety.

Image guided surgery is designed to help surgeons target the brain tumor with pinpoint accuracy. Accurately locating and removing the brain tumor is important and helps surgeons to preserve the patient’s brain functions after surgery. Studies have shown that functional neuronavigation can improve surgical outcomes for complex surgeries.

It has been demonstrated that functional neuronavigation improves surgical outcomes, particularly for complex surgeries.3,4,5
