Neuronavigation systems offer high mechanical accuracy in complex brain and spinal surgeries. This frameless technology has proven reliable in over 120 operations, aiding localization and surgical planning.

Area of Science:

  • Neurosurgery
  • Medical Technology
  • Image-Guided Surgery

Background:

  • Neuronavigation systems are increasingly utilized in complex surgical procedures.
  • Accurate localization and planning are critical for neurosurgical interventions.
  • Previous systems may have limitations in accuracy or application scope.

Purpose of the Study:

  • To evaluate the efficacy and reliability of a neuronavigation system in a large cohort of neurosurgical operations.
  • To assess the system's accuracy in localizing deep-seated lesions and guiding instrumentation.
  • To determine the system's utility in surgical planning for various neurosurgical conditions.

Main Methods:

  • A neuronavigation system was employed in over 120 neurosurgical operations over two years.

  • Image guidance utilized computed tomography (CT) or magnetic resonance imaging (MRI) with 2-3 mm slice thickness.
  • Patient demographics included ages from 12 months to 75 years, with equal sex distribution.

    • Main Results:

    • The system demonstrated high mechanical accuracy in surgical localization for deep-seated masses and epileptic foci.
    • Successful application in surgical planning for brain tumors and arteriovenous malformations.
    • Effective guidance of instrumentation in spinal surgery cases.
    • No mechanical failures were reported during the study period.
    • The system was used in 50 deep-seated mass cases, 50 tumor/vascular mass excision cases, and 20 spinal instrumentation cases.

    Conclusions:

    • Neuronavigation is a valuable technology for frameless brain and spinal surgeries.
    • The system provides reliable and accurate guidance, enhancing surgical precision.
    • Its application spans diverse neurosurgical interventions, from tumor resection to spinal procedures.
