Area of Science:

  • Otolaryngology
  • Medical Technology
  • Pediatric Surgery

Background:

  • Computer-assisted navigation (CAS) systems offer potential benefits in surgical precision.
  • Adaptation of existing CAS technology for pediatric endoscopic sinusonasal surgery presents unique challenges.

Purpose of the Study:

  • To introduce and evaluate a modified computer-assisted navigation system for pediatric sinusonasal surgery.
  • To assess the system's feasibility, accuracy, and indications in a pediatric population.

Main Methods:

  • A commercially available wireless passive marker CAS was adapted for pediatric use.
  • The system was employed during various pediatric endoscopic sinusonasal surgical procedures.
  • Modifications included a laser device for improved computed tomographic (CT) scan correlation.

Main Results:

  • Initial challenges with headset acceptance were overcome.
  • Setup time decreased significantly from 20 minutes to 3 minutes.
  • Average recording accuracy was 1.1 mm, with increasing advantages noted in complex cases.

Conclusions:

  • The computer-assisted navigation system proved effective as both a control and surgical guide in pediatric sinusonasal surgery.
  • Indications for its use expanded with increasing surgeon experience.
  • The system, combined with endoscopic and CT views, enhances pediatric intranasal surgical procedures.
