Summary
Navigation technology in endonasal surgery has varied indications, from redundant to necessary. For standardized procedures like ethmoidectomy, navigation may hinder quality and offer no outcome advantage.
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Technology
Background:
- The impact of navigation technology in endonasal surgery remains debated.
- Cost-effectiveness, including investment and time, is a key consideration.
Purpose of the Study:
- To evaluate the impact of navigation technology on endonasal surgery outcomes.
- To classify indications for navigation based on risk-benefit-cost analysis.
Main Methods:
- Retrospective analysis of quality assurance data from 56 patients.
- Comparison of surgical times (preparation, setup, actual surgery) with navigation use.
- Surgeons of varying experience levels were included.
Main Results:
- A four-category classification for navigation indications was developed: redundant, reasonable, helpful, and necessary.
- Navigation is considered redundant if it offers no clear process or outcome improvement.
- Navigation is necessary when surgery cannot be justified without it or requires intraoperative imaging.
Conclusions:
- Indications for navigation in endonasal surgery depend on risk-benefit-cost analysis.
- In standardized procedures (e.g., ethmoidectomy), navigation may impede process quality and offer no outcome benefits.
