Area of Science:

  • Neurosurgery
  • Surgical Navigation
  • Skull Base Surgery

Background:

  • Intraoperative navigation systems are integral to ENT, oral/maxillofacial, and neurosurgery.
  • Anatomical shifts during surgery can compromise navigation accuracy, especially in brain tumor resection.
  • Intraoperative imaging and navigation integration address accuracy limitations.

Purpose of the Study:

  • To evaluate the role and benefits of intraoperative navigation in skull base surgery.
  • To explore how navigation aids interdisciplinary collaboration in complex anatomical regions.
  • To assess the impact of navigation integration with other technologies on patient outcomes.

Main Methods:

  • Review of intraoperative navigation system applications in neurosurgery and ENT.
  • Analysis of navigation's utility in skull base surgery, considering anatomical stability.
  • Integration of navigation with intraoperative imaging, electrophysiological monitoring, and radiosurgery.

Main Results:

  • Navigation accuracy is less affected by shifts in skull base surgery due to bony structures.
  • Navigation facilitates interdisciplinary approaches in skull base pathologies.
  • Integration with function monitoring and radiosurgery enhances radical resection while reducing morbidity.

Conclusions:

  • Intraoperative navigation is a valuable tool in skull base surgery, improving interdisciplinary cooperation.
  • Technological integration (imaging, monitoring, radiosurgery) supports less invasive and more radical tumor resection.
  • Future systems enabling direct linking of resection data to radiotherapy planning will further enhance patient care and follow-up.
