Computer-assisted surgery (CAS) systems enhance safety in ENT procedures by precisely tracking instruments near vital structures. These navigation tools help prevent inadvertent injuries during complex surgeries.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation

Background:

  • Endonasal endoscopic procedures carry risks due to proximity to critical anatomical structures.
  • Minimizing surgical trauma to the orbit, skull base, and carotid artery is paramount.

Purpose of the Study:

  • To evaluate two computer-assisted navigation systems for endonasal endoscopic surgery.
  • To assess the efficacy of these systems in reducing the risk of iatrogenic injury.

Main Methods:

  • Comparison of the ARTMA Virtual Patient (magnetic field tracking) and ISG-system (mechanical arm localization).
  • Assessment of instrument position correlation with CT/MR images in submillimeter range.

Main Results:

Related Experiment Videos

  • Computer-Assisted-Surgery (CAS) did not significantly increase surgical time.
  • CAS systems were found to prevent inadvertent surgical injuries.
  • Previous studies confirm CAS minimizes complications in frontobasis surgeries.

Conclusions:

  • CAS systems are valuable tools for experienced surgeons in endonasal procedures.
  • These navigation systems aid in preventing inadvertent injury to vital structures.
  • CAS complements, but does not replace, surgeon expertise.
