Area of Science:

  • Otolaryngology
  • Medical Engineering
  • Surgical Navigation

Background:

  • 3D computer-assisted navigation systems are increasingly used in ENT surgery.
  • Accessing deep or complex anatomical regions, such as paranasal sinuses, can be challenging with standard surgical tools.

Purpose of the Study:

  • To evaluate the intraoperative utility and accuracy of newly developed bent probes for 3D computer-assisted navigation in ENT surgery.
  • To assess the benefit of these probes in accessing remote sinus locations.

Main Methods:

  • Standardized calibration of bent probes for use with the ISG Viewing Wand navigation system.
  • Intraoperative application of bent probes during paranasal sinus surgery.
  • Evaluation of probe compliance with the navigation system's accuracy standards.

Main Results:

  • The bent probes were successfully integrated into the navigation system.
  • Standardized calibration ensured the probes met the navigation system's accuracy requirements.
  • The bent probes facilitated easier access to the maxillary and frontal sinuses.

Conclusions:

  • Bent probes are a valuable tool for intraoperative 3D computer-assisted navigation in ENT, particularly for paranasal sinus surgery.
  • These probes improve surgical access to challenging anatomical sites.
  • Clinical experience supports the beneficial application of bent probes in enhancing surgical navigation accuracy and efficiency.
